Does "Selfhosted" mean you actually have a server at home?
I'm trying to better understand hosting a Lemmy Instance. Lurking discussions it seems like some people are hosting from the Cloud or VPS. My understanding is that it's better to futureproof by running your own home server so that you have the data and the top most control of hardware, software etc. My understanding is that by hosting an instance via Cloud or VPS you are offloading the data / information to a 3rd party.
Are people actually running their own actual self-hosted servers from home? Do you have any recommended guides on running a Lemmy Instance?
Selfhosting is the act of hosting applications on "hardware you control". That could be rented or owned, its the same to us. You could go out and buy a server to host your applications but there a few issues that you might run into that could prevent you from simply standing up a server rack in your spare room. From shitty ISPs to lack of hardware knowledge there are plenty of reasons to just rent a VPS. Either way youre one of us :)
But you don't control the hardware if you run it on a VPS?
You control the hardware you are provisioned and the software you run on it, which is enough for me. Unless you're looking for a job in the server adminstration/maintenance field the physical hardware access component of it matters less IMO
You definitely don't control the hardware. Someone else at some remote server farm or something does.
Some of them offer what they call bare metal provisioning and I wonder if some even offer ILOM type access. That’s pretty much control of the hardware for me. Just that you can’t plug in a disk or a memory stick.
If your server has IPMI, there's little difference between being there in person and not.
Self hosting basically means you are running the server application yourself. It doesn't matter if it's at home, on a cloud service or anywhere else.
I wouldn't recommend hosting a social network like lemmy, because you would be legally responsible for all the content served from your servers. That means a lot of moderation work. Also, these types of applications are very demanding in terms of data storage, you end up with an ever growing dataset of posts, pictures etc.
But self hosting is very interesting and empowering. There are a lot of applications you can self host, from media servers (Plex, Jellyfin), personal cloud (like Google Drive) with NextCloud, blocking ads with pihole, sync servers for various apps like Obsidian, password manager BitWarden etc. You can even make your own website by coding it, or using a CMS platform like WordPress.
Check the Awesome Self-hosted list on GitHub, has a ton of great stuff.
And in terms of hardware, any old computer or laptop can be used, just install your favorite server OS (Linux, FreeBSD/OpenBSD, even Windows Server). You can play with virtualization too if you have enough horsepower and memory with ESXI or Proxmox, so you can run multiple severs at once on the same computer.
Me, yes. But it's still selfhosting if you do it on a VPS. And probably easier, too. I mainly do it at home, because I can have multiple large harddisks this way. And storage is kind of expensive in the cloud.
Depending on where you are, a hard drive that runs 24/7 can cost you quite a bit of money (6$/month or even more for just the hard drive). If you consider the upfront cost of a hard drive, the benefit of hosting at home gets even smaller. Nvme is where you really save money hosting at home. Personally I do both, because cloud is cheap and you can have crazy bandwiths.
I know. You pretty much need to know what you're doing. And do the maths. Know the reliability (MTBF/MTTF) and price. Don't forget to multiply it by two (as I forgot) because you want backups. And factor in cost of operation. And corresponding hardware you need to run to operate those hdds. My hdd spins down after 5 minutes. I live in Europe and really get to pay for electricity as a consumer. A data center pays way less. My main data, mail, calendar and contacts, OS, databases and everything that needs to be there 24/7 fits on a 1TB solid state disk that doesn't need much energy while idle. So the hdd is mostly spun down.
Nonetheless, I have a 10TB hdd in the basement. I think it was a bit less than 300€ back when I bought it a few years ago. But I can be mistaken. I pay about 0.34€/kWh for (green) electricity. But the server only uses less than 20W on average. That makes it about 4€ per month in electricity for me. And I think my homeserver cost me about 1000€ and I've had it since 2017. So that would be another ~15€ per month if I say I buy hardware for ~1100€ every 6 years. Let's say I pay about 20€/month for the whole thing. I'm not going to factor in the internet connection, because I need that anyways. (And I probably forgot to factor in I upgraded the SSD 2 times and bought additional RAM when it got super cheap. And I don't know the reliability of my hdds...)
I also have a cheap VPS and they'd want 76,27€/month ... 915.24€ per year if I was to buy 10TB of storage from them. (But I think there are cheaper providers out there.) That would have me protected against hard disk failures. It'll probably get cheaper with time, I can scale that effortlessly and the harddisks are spun up 24/7. The harddisks are faster ones and their internet connection is also way faster. And I can't make mistakes like with my own hardware. Maybe having a hdd fail early or buy hardware that needs excessive power. And that'd ruin my calculation.... In my case... I'm going with my ~20€/month. And I hope I did the maths correctly. Best bang for the buck is probably: Dont have the data 24/7 available and just buy an external 10TB hard drive if your concern is just pirating movies. Plug it in via USB into whatever device you're using. And make sure to have backups ;) And if you don't need vast amounts of space, and want to host a proper service for other people: just pay for a VPS somewhere.
You forgot something in your calculations, you don’t need a complete VPS for the *arrs. App hosting/seedboxes are enough for that and you can have them for very, very cheap.
Ahem, I don't need a seedbox at all. I use my VPS to host Jitsi-Meet, PeerTube and a few experiments. The *arrs are for the people over at !piracy@lemmy.dbzer0.com
That you probably need a VPS for, yes.
I'd say there are levels to selfhosting. Hosting your stuff on the cloud is selfhosting, but hosting it on your own hardware is a more "pure" way of doing it imo. Not that it's better, both have their advantages, but it's certainly a more committed to the idelal
I don't know what hosting on the VPS should be called but it is definitely not self hosting. Since you are hosting your services on someone else's servers. Didn't it used to be called colo or something like that.
I thought colo was your hardware in someone else's data center.
For me though a VPS is still self hosting because you own your applications data and have control over it.
You're less beholden to the whims of a company to change the software or cut you off. With appropriate backups you should be able to move to a new cloud provider fairly easily.
I disagree. Selfhosting is not specific to hardware location for me. My own git server is definitely selfhosted, VPN, and so on.
I agree that having your own hardware at home is a more pure way of doing it, but I'd just call that a Homelab. I personally just combine both.
Of course it's self hosting. The term "self hosting" just means being in control of the service or host yourself, as opposed to that being controlled by a third party.
It doesn't mean the hardware has to be in your house. It just so happens that that is the majority preference, because people value privacy, and are often hosting private data.
I'd like to pose the fact that VPSes and Hosted solutions are different as a rebuttle to what you're saying. It's pretty unreasonable to gate keep self hosting behind having the hardware running on a device you control.
Yup, it's more like self administration or something like that
I haven't got any piece of hardware that was sold with the firstname "Server".
But there's this self-built PC in my room that's running 24/7 without having to reboot in several years...
Well technically a "server" is a machine dedicated to "serving" something, like a service or website or whatever. A regular desktop can be a server, it's just not built as well as a "real" server.
There is though reasons to stray from certain consumer products for server equipment.
Yeah I'd stay away from Mac too... but seriously most modern laptops can disable any sleep/hibernation on lid close
My go to lately is Lenovo tiny, can pick them up super cheap with 6-12 month warranties, throw in some extra ram, a new drive, haven't had any fail on me yet
You should think before releasing dangerous information on the internet!
You can get a 2core 8GB / 240GB for 75€!!
Uh oh, I think I'll have to buy one now...
This is my little setup at the moment. Each is 8500t CPU, 32gb ram, 2tb nvme and 1tb SATA SSD all running in a proxmox cluster
Edit: also check out Dell micro or the hp... Uh I want to say it's g6 micro? You might need to search for what is actually called
Heh, this is awesome 😅
Thanks :D the frame and all parts are self designed and 3d printed... was a fun project
The whole thing runs from just 2 power cables with room for another without adding any extra power cables
Not at all overkill? :-D
Future proofing or is it really used ? I don't know proxmox, is it some docker launcher thingy?
Very cool anyways!
Proxmox is like esxi, it lets you setup virtual machines. So you can fire up a virtual Linux machine and allocate it like 2gb ram and limit it to 2 cores of the CPU or give it the whole lot depending on what you need to do
Having them in a cluster let's them move virtual machines between the physical hardware and have complete copies so if one goes down the next can just start up
It is a little overkill, I'm probably only using about 20% of its resources but it's all for a good cause. I'm currently unable to work due to kidney failure but I'm working towards a transplant. If I do get a transplant and can return to work, being able to say "well this is my home setup and the various things I know how to do" looks a lot better than "I sat on my ass for the last 4 years so I'm very rusty"
This whole setup cost me about $1000aud and uses 65-70w on average
Hey good luck man!
Good idea, just sitting around isn't good for mental health either.
So back to tech :-) is it like docker / Kubernetes but with VM right? What's the good/bad things concerning VM Vs Docker?
BTW that's not a lot of power consumption!
And yeah if it's not overkill they you are morally obliged to search for ways to make it so, right :-) ?!
Cheers
Docker/kubernetes and VMS are similar in that they are all virtualisation but the similarity kinda end there. Love them or hate them, Each has its own important role in IT infrastructure.
First off, docker itself needs a host operating system to run. Secondly, Docker are containers. Each image is built on a cut down version of the operating system generally to perform one specific task or run one specific application. The environment is preconfigured to work exactly as intended so generally speaking, you don't get the whole "but it works on my machine"
Kubernetes I'm not the most qualified to speak to, but pretty much someone said "ok docker is great but we want redundancy, scalability, etc" and made kubernetes.
A vm is a full virtual machine. You can give it virtual harddisks, virtual network cards, etc. You then install a full operating system on it, could be windows or Linux or whatever you need.
From there you can install docker if that's what you want, or can install specific apps. This is the first difference, is if you install the app compared to a docker container, you need to make sure you have all the prerequisites met, all the correct compatibility, etc. It's up to you to make sure your system is correct for the software.
Another major difference is docker containers are all seen on the network as coming from whatever the host machine's IP is.
Whereas the network views each vm as it's own device on the network, giving each it's own IP (if using dhcp) and allowing things like vlans and things.
As for my setup, I have 3 VMs with docker servers, each with between 20-30 docker containers, 3 VMs running adguard DNS, 1 vm acting as a tailscale entry point, then a few application specific VMs. It's handy just being able to fire up a blank Ubuntu instance to play with me software, and if anything goes wrong just delete the whole machine and start fresh.
Then for storage behind it all, I have a qnap ts453d with 4x 8tb drives.
Then outside my home, I have 2 X Oracle hosted VMs, one hosting about 22 websites and all the stuff they need, one acting as a tunnel into my home services since I'm behind a CGNAT, and then another physical server located in the local data centre running email for a few small businesses and myself
Thank you for the thorough explanation!
I think a VM for me would only bf a windows on inux for like Photoshop and 3dsmax :-)
Docker though seems interesting for a simple user like me.
Thanks again !
Cheers
No worries, in terms of docker, if you want to see some of the more useful docker things along with explanation of how to get them running, check out https://noted.lol and https://mariushosting.com
Noted has a lot of writeups on various projects that are nearly entirely docker based. Marius focuses more on docker projects on Synology but for many of them you can go to the project home to get the generic docker instructions and just read his one for project descriptions and intially setup guides
Doesn't that mean, tiny fans howling all day long?
Only if you've got it cranking all day. I've got a couple of Tiny (they're Micro, which is the same thing) systems that are silent when idle and nearly silent when running less than a load avg of 5. It's only if I try to spin up a heavy, CPU-bound process that their singular fan spins fast enough to be noticable.
So don't use one as a Mining rig, but if you want something that runs x64 workloads at 9-20 watts continuously, they're pretty good.
Even running at full speed mine are pretty quiet but I also have 80mm silent low rpm fans blowing air across them too which seems to help
I also recently went through with fresh thermal paste
Just set it to "do nothing" when lid is closed. That's all.
FWIW, this free app solves for that issue well; I have several clammed Macs running it right now:
https://apps.apple.com/us/app/amphetamine/id937984704?mt=12
100%, and this is why businesses don't use laptops as servers... typically 😂.
just break the screen off. call it a headless sever.
How do you install security updates etc without restarting?
Linux servers prompt you do restart after certain updates do you just not restart?
Enterprise distributuions can hot-swap kernels, making it unnecessary to reboot in order to make system updates.
Microsoft needs to get its shit together because reboots were a huge point of contention when I was setting up automated patching at my company.
Good luck with that, I have all reboot options off but yesterday it just rebooted like that. Thanks MS.
The right way (tm) is to have the application deployed with high availability. That is every component should have more than one server serving it. Then you can take them offline for a reboot sequentially so that there's always a live one serving users.
This is taken to an extreme in cloud best practices where we don't even update any servers. We update the versions of the packages we want in some source code file. From that we build a new OS image contains the updated things along with the application that the server will run and it's ready to boot. Then in some sequence we kill server VMs running the old image and create news ones running the new. Finally the old VMs are deleted.
You can just restart... with modern SSDs it takes less than a minute. No one is ging to have a problem with 1 minute downtime per month or so.
Actually I am lazy with updates on the "bare metal" debian/proxmox. It does nothing else than host several vm's. Even the hard disks belong to a vm that provides all the file shares.
Do you have any recommended resources for getting started? I do have a secondary PC...
First, you need a use-case. It's worthless to have a server just for the sake of it.
For example, you may want to replace google photos by a local save of your photos.
Or you may want to share your movies accross the home network. Or be able to access important documents from any device at home, without hosting them on any kind of cloud storage
Or run a bunch of automation at home.
TL;DR choose a service you use and would like to replace by something more private.
Get a copy of vmware (esxi) or proxmox and load it on that secondary pc.
Proxmox absolutely changed the game for me learning Linux. Spinning up LXC containers in seconds to test out applications or simply to learn different Linux OSs without worrying about the install process each time has probably saved me days of my life at this point. Plus being able to use and learn ZFS natively is really cool.
Ive been using esxi (free copy) for years. Same situation. Being able to spin up virtual machines or take a snapshot before a major change has been priceless. I started off with smaller nuc computers and have upgraded to full fledged desktops.
I don't know where to start today, honestly.
I started with books a long time ago:
https://www.amazon.com/Algorithms-Data-Structures-Niklaus-Wirth/dp/0130220051
https://www.amazon.de/-/en/Andrew-S-Tanenbaum/dp/0132126958
https://www.amazon.de/Programming-Language-Prentice-Hall-Software/dp/0131103628
The simple way is to Google 'yunohost' and install that on your spare machine, then just play around with what that offers.
If you want, you could also dive deeper by installing Linux (e.g.Ubuntu), then installing Docker, then spin up Portainer as your first container.
Years? Lol you should update that software.
Well, there are specific hardware configurations that are designed to be servers. They probably don't have graphics cards but do have multiple CPUs, and are often configured to run many active processes at the same time.
But for the most part, "server" is more related to the OS configuration. No GUI, strip out all the software you don't need, like browsers, and leave just the software you need to do the job that the server is going to do.
As to updates, this also becomes much simpler since you don't have a lot of the crap that has vulnerabilities. I helped manage comuter department with about 30 servers, many of which were running Windows (gag!). One of the jobs was to go through the huge list of Microsoft patches every few months. The vast majority of which, "require a user to browse to a certain website" in order to activate. Since we simply didn't have anyone using browsers on them, we could ignore those patches until we did a big "catch up" patch once a year or so.
Our Unix servers, HP-UX or AIX, simply didn't have the same kind of patches coming out. Some of them ran for years without a reboot.
"Self-hosted" means you are in control of the platform. That doesn't mean you have to own the platform outright, just that you hold the keys.
Using a VPS to build a Nextcloud server vs using Google Drive is like the difference between leasing a car and taking a taxi. Yes, you don't technically own the car like you would if you bought it outright, but that difference is mostly academic. The fact is you're still in the driver's seat, controlling how everything works. You get to drive where you want to, in your own time, you pick the music, you set the AC, you adjust the seats, and you can store as much stuff in the trunk as you want, for as long as you want.
As long as you're the person behind the metaphorical wheel, it's still self-hosting.
My lemmy instance is hosted in my basement
I'm sure the original spirit of selfhosting is actually owning the hardware (whether enterprise- or consumer-grade) but depending on your situation, renting a server could be more stable or cost effective. Whether you own the hardware or not, we all (more or less) have shared experiences anyway.
Where I live, there are some seasons wherein the weather could be pretty bad and internet or electricity outages can happen. I wouldn't mind hours or even days of downtime for a service whose users are only myself or a few other people (i.e. non-critical services) like a private Jellyfin server, a Discord bot, or a game server.
For a public Lemmy server, I'd rather host it on the cloud where the hardware is located in a datacenter and I pay for other people to manage whatever disasters that could happen. As long as I make regular backups, I'm free to move elsewhere if I'm not satisfied with their service.
As far as costs go, it might be cheaper to rent VMs if you don't need a whole lot of performance. If you need something like a dedicated GPU, then renting becomes much more expensive. Also consider your own electricity costs and internet bills and whether you're under NAT or not. You might need to use Cloudflare tunnels or rent a VPS as a proxy to expose your homeserver to the rest of the world.
If the concern is just data privacy and security, then honestly, I have no idea. I know it's common practice to encrypt your backups but I don't know if the Lemmy database is encrypted itself or something. I'm a total idiot when it comes to these so hopefully someone can chime in and explain to us :D
For Lemmy hosting guides, I wrote one which you can find here but it's pretty outdated by now. I've moved to rootless Docker for example. The Lemmy docs were awful at the time so I made some modifications based on past experiences with selfhosting. If you're struggling with their recommended way of installing it, you can use my guide as reference or just ask around in this community. There's a lot of friendly people who can help!
Yep, big ol' case under my desk with some 20TB of storage space.
Most of what I host is piracy related 👀
how much of the 20tb is used?
Free space is wasted space
~19.5 tb of hardcore midget porn
~500 gigs of whale sounds to help me sleep
Whoops that was backwards, my bad
~19.5 tb of hardcore whale porn
~500 gigs of midget sounds to help me sleep
Whale sounds! Oh man, I'm gonna add that to ELF space radio and rain recordings!
There's about 3.5 TB to go out of an actual 18 in the server.
I have another 2TB to install but it's not in yet.
I'm also transcoding a lot of my media library to x265 to save space.
I don't download for the sake of downloading, usually, and i delete stuff if I don't see value in keeping it.
What is a good transcoder? I haven't ran my media through one. Is the space saving significant? Did you lose video quality?
In order:
FFMPEG, yes, no.
I refer you to this comment for more info.
I have seen a saving of 60-80% per file on lower resolutions like 720 or 1080, which makes the server time well worth it.
A folder of 26 files totaling 61GB went down to 10.5, for example.
Some stuff is just better hosted in a proper data center. Like mail, DNS or a search engine. Some stuff, like sensitive data, is better hosted on your own hardware in your home.
There are definitely benefits on running a server at home but you could say the same of a VPS. As long as you control it, it is self hosted in my book.
Isn't control limited on 3rd party hosts for security purposes?
Not really, you're ideally paying for a server that you have complete control of. The differences are mostly just fundamental limitations.
Example: if you're hosting off site, you will always be connecting remotely, so your access depends on a network connection. If you're hosting at home then your stuff is still accessible when your internet goes down
It is, if you can host at home and use a cheap vps as proxy is better in my opinion. Like it or not when you host something you will put sensitive info in your vps and ofc you should trust them. Exactly like the vpn providers, they will fight for your rights paying 5 dolars/months? For sure no.
Or your Internet provider, they will also not fight for your rights paying $30 a month.
My services are not accessible from my wan, i forward all my services to a cheap vps,using a proxy and trafic is encrypted. So i am not worried about my isp also my real ip is hiden. I use something like cloudflare zero trust.. but is open source.
I'm less worried aobut sensitive info and more worried about owning the data. I'm looking to avoid a sitaution where I offload all the data to a 3rd party and lose access or pricing get expensive (like a Reddit situation). I'm more worried by offloading the data to a 3rd party I can't verify that they're not reselling it. etc.
@ProtecyaTec@lemmy.world not sure what that means but I guess you can do certain thing in your home server not allowed on a VPS. OTOH, an email server at home for example is much more difficult to achieve because your ISP most likely won’t allow you to open port 25
I was just reading through
Lemmy-AnsibleGithub docs and wasn't sure if a 3rd party server or a home server was going to be better to run. The documentation doesn't feel super user-friendly or maybe I'm just not as tech-savvy as I thought.@ProtecyaTec@lemmy.world idk about ansible but if you are starting I would recommend starting small, in your personal computer. Docker is a good way to start
This may be way of scope for this thread but I'm not sure a better place yet to ask and learn more about how all this works. Say I run my Docker Container from a home PC, how do I make my Lemmy Instance accessible to the public? I'm familiar with web hosting but only from hosting on a simple 3rd party, where you buy a domain.
Agree with the VPS in this case. For sure you can create public-facing services in a home server or home lab, but to do so you need:
If you're new to these things, Id start with something more mature for personal or family home use first. Like NextCloud, HomeAssistant or Jellyfin media server. Lots of YouTubers have covered how these can be set up as a reference.
Lemmy is still alpha, full of bugs and security vulnerabilities and needs regular hotfixes and babysitting. Permitting Joe Public into your home services is ripe for disaster unless you have the time and expertise.
Operating internet-facing services in the home, in my opinion, requires a layer-3 managed switch so that internet traffic is 100% separated from home traffic, w/attendant DMZ to bridge home<-> internet-facing services safely.
L3 managed is the simplest method to contain a penetration to just the internet-facing devices (which is still pretty bad). Cloud hosting is more manageable, but you must watch the spend.
The biggest issue is a DDoS attack on the home network, which could impact internet-facing services and home clients (streaming TV, gaming, email, etc.).
Agree. Best to have that dedicated hardware, and a degree in network engineering first! Hah :)
::: spoiler tech waffle... You might achieve network isolation without dedicated managed switches by: using prosumer routers or OpenWRT, with a Hypervisor like Proxmox, which support VLAN tagging. But this wouldn't save your home connection from a DDoS. To help with that, running public services behind CloudFlare seems to be one of the better choices, even our Lemmy hosts are using. :::
If you're starting out, best keep internet facing home services private through a VPN, maybe ZeroTier or TailScale. Don't advertise them publically at all.
@ProtecyaTec@lemmy.world yeah if you want to host something like Lenny you may be able to do it on a home server but in terms of ports blocked, security, etc I guess it is easier to run it in a VPS
Most people who "self host" things are still doing it on a server somewhere outside their home. Could be a VPS, a cloud instance, colocated bare metal, ...
Certain cloud providers are as secure, if not more secure, than a home lab. Amazon, Google, Microsoft, et al. are responding to 0-day vulnerabilities on the reg. In a home lab, that is on you.
To me, self-hosted means you deploy, operate, and maintain your services.
Why? Varied...the most crucial reason is 1) it is fun because 2) they work.
Listing Microsoft cloud after their recent certificate mess is an interesting choice.
Also, the "cloud responds to vulnerability" only works if you're paying them to host the services for you - which definitely no longer is self hosting. If you bring up your own services the patching is on you, no matter where they are.
If you care about stuff like "have some stuff encrypted with the keys in a hardware module" own hardware is your only option. If you don't care about that you still need to be aware that "cloud" or "VPS" still means that you're sharing hardware with third parties - which comes with potential security issues.
Well with bare metal yes, but when your architecture is virtual, configuration rises in importance as the first line of defense. So it’s not just “yum —update” and reboot to remediate a vulnerability, there is more to it; the odds of a home lab admin keeping up with that seem remote to me.
Encryption is interesting, there really is no practical difference between cloud vs self hosted encryption offerings other than an emotional response.
Regarding security issues, it will depend on the provider but one wonders if those are real or imagined issues?
You'll have all the virtualization management functions in a separate, properly secured management VLAN with limited access. So the exposed attack surface (unless you're selling VM containers) is pretty much the same as on bare metal: Somebody would need to exploit application or OS issues, and then in a second stage break out of the virtualization. This has the potential to cause more damage than small applications on bare metal - and if you don't have fail over the impact of rebooting the underlying system after applying patches is more severe.
On the other hand, already for many years - and way before container stuff was mature - hardware was too powerful for just running a single application, so it was common to have lots of unrelated stuff there, which is a maintenance nightmare. Just having that split up into lots of containers probably brings more security enhancements than the risk of having to patch your container runtime.
Most of the encryption features advertised for cloud are marketing bullshit.
"Homomorphic encryption" as a concept just screams "side channel attacks" - and indeed as soon as a team properly looked at it they published a side channel paper.
For pretty much all the technologies advertised from both AMD and intel to solve the various problems of trying to make people trust untrustworthy infrastructure with their private keys sidechannel attacks or other vulnerabilities exist.
As soon as you upload a private key into a cloud system you lost control over it, no matter what their marketing department will tell you. Self hosted you can properly secure your keys in audited hardware storage, preventing key extraction.
Just look at the Microsoft certificate issue I've mentioned - data was compromised because of that, they tried to deny the claim, and it was only possible to show that the problem exists because some US agencies paid extra for receiving error logs. Microsofts solution to keep you calm? "Just pay extra as well so you can also audit our logs to see if we lose another key"
The azure breach is interesting in that it is vs MSFT SaaS. We’re talking produce, ready to eat meals are in the deli section!
The encryption tech in many cloud providers is typically superior to what you run at home to the point I don’t believe it is a common attack vector.
Overall, hardened containers are more secure vs bare metal as the attack vectors are radically diff.
A container should refuse to execute processes that have nothing to do with container function. For ex, there is no reason to have a super user in a container, and the underlying container host should never be accessible from the devices connecting to the containers that it hosts.
Bare metal is an emotional illusion of control esp with consumer devices between ISP gateway and bare metal.
It’s not that self hosted can’t run the same level of detect & reject cfg, it’s just that I would be surprised if it was. Securing self hosted internet facing home labs could almost be its own community and is definitely worth a discussion.
My point is that it is simpler imo to button up a virtual env and that includes a virtual network env (by defn, cloud hosting).
They rely on hardware functionality in Epyc or Xeon CPUs for their stuff - I have the same hardware at home, and don't use that functionality as it has massive problems. What I do have at home is smartcard based key storage for all my private keys - keys can't be extracted from there, and the only outside copy is a passphrase encrypted based64 printout on paper in a sealed envelope in a safe place. Cloud operators will tell you they can also do the equivalent - but they're lying about that.
And the homomorphic encryption thing they're trying to sell is just stupid.
Assuming you put the same single application on bare metal the attack vectors are pretty much the same - but anybody sensible stopped doing that over a decade ago as hardware became just too powerful to justify that. So I assume nowadays anything hosted at home involves some form of container runtime or virtualization (or if not whoever is running it should reconsider their life choices).
Just like the container thing above, pretty much any deployment nowadays (even just simple low powered systems coming close to the old bare metal days) will contain at least some level of virtual networking. Traditionally we were binding everything to either localhost or world, and then going from there - but nowadays even for a simple setup it's way more sensible to have only something like a nginx container with a public IP, and all services isolated in separate containers with various host only network bridges.
I like how you have a home smartcard. I can’t believe many do.
Why do you think cloud operators are lying?
Pretty much anyone should do. There's no excuse to at least keep your personal PGP keys in some USB dongle. I personally wouldn't recommend yubikey for various reasons, but there are a lot more options nowadays. Most of those vendors also now have HSM options which are reasonably priced and scale well enough for small hosting purposes.
I started a long time ago with empty smartcards and a custom card applet - back then it was quite complicated to find empty smartcards as a private customer. By now I've also switched to readily available modules.
One of the key concepts of the cloud is that your VMs are not tied to physical hardware. Which in turn means the key storage also isn't - which means extraction of keys is possible. Now they'll tell you some nonsense how they utilize cryptography to make it secure - but you can't beat "key extraction is not possible at all".
For the other bits I've mentioned a few times side channel attacks. Then there's AMDs encrypted memory (SEV) claiming to fully isolate VMs from each other, with multiple published attacks. And we have AMDs PSP and intels ME, both with multiple published attacks. I think there also was a published attack against the key storage I described above, but I don't remember the name.
I agree that our stuff is unlikely to be victim of an targeted attack in the cloud - but could be impacted by a targeted attack on something sharing bare metal with you. Or somebody just managed to perfect one of the currently possible attacks to run them larger scale for data collection - in all cases you're unlikely to be properly informed about the data loss.
I mean, as long as you patch regularly and keep backups, you should be good enough. That's most of what responding to a zero day is, anyway, patching.
My "server" is just my old gaming PC that I slapped Ubuntu on.
My "Server" is a small 32bit ARM Orangepi.
Server is a description oft function, formfactor. You are OK.
I have a salvaged HP 3500 Pro with an HTPC case and 8.5 TB storage. Started mainly for Jellyfin and now have half a dozen docker containers on it. Great test bed for getting used to linux before I slowly creep towards having it as my main OS on my PC.
I'm starting to realize that jellyfin is a gateway drug to self-hosting. And I'm here for it.
That's how it started with me. Now I have the arr stack and a bunch of other stuff running. It's definitely been a fun learning experience. It's a lot nicer just giving the wife a jellyseerr icon on her phone instead of her giving me a long list of stuff she wants and I have to find them.
Me: I got a small plex server going to save money compared to steaming....
Narrator: He did not.
No that's a homelab. Selfhosted applies to the software that you install and administrate yourself so you have full control over it. If it was about running hardware at home we'd see more posts about hardware.
I would say that a homelab is more about learning, developing, breaking things.
Running esoteric protocols, strange radio/GPS setups, setting up and tearing down CI/CD pipelines, autoscalers, over-complicated networks and storage arrays.
Whereas (self)hosting is about maintaining functionality and uptime.
You could self-host with hardware at home, or on cloud infra. Ultimately it's running services yourself instead of paying someone else to do it.
I guess self-hosting is a small step away from earning money (or does earn money). Reliable uptime, regular maintenance etc.
Homelabbing is just a money sink for fun, learning and experience. Perhaps your homelab turns into self-hosting. Or perhaps part of your self-hosting infra is dedicated to a lab environment.
Homelab is as much about software as it is about hardware. Trying new filesystems, new OSs, new deployment pipelines, whatever
It's not strictly defined like that. Some people do, others don't.
Do you think that the majority host from a 3rd party services or hosts from a home server?
I started at home and then moved into a vps for my lemmy instance. I decided I don't want all that public traffic hitting my home ip.
Which VPS do you recommend?
I'm using Racknerd. They came highly recommended and I've been happy so far.
Check out lowendbox.com for vps reviews and deals.
My website/blog is in the cloud but anything that needs local storage or internet access (everything else) is virtualized in a container on proxmox.
It's easier and quicker to start with a VPS and most people do that. On the low end it is usually also cheaper (unless you already have or can get second hand hardware almost for free).
However, if you are starting to get higher storage and compute needs, currently especially also GPU compute, hosting from home can be very interesting as it is much cheaper in the longer term and the hardware side is interesting to learn as well.
I do both. I have a custom built NAS based on a Ryzen 3600 and ZFS across 4 drives which runs about 20 self hosted applications and stores the majority of my files but its only accessible from within the home. I also rent a small VPS for personal webspace and hosting self hosted apps I want out of the house.
In the past I have also hosted raw servers from Hetzner or bigger VPS from Amazon for the purpose of hosting a game server. Alongside those I often had community applications like website, forums, wikis and custom chat and voice comms services.
Its all self hosting to me since I run it. The various options are all about the trade offs of security, accessibility, cost and performance. The cheaper cloud options when you add it up can be cheap compared to buying and running your own hardware when you take into account electrical costs and the likely hardware replacement needs within 5 years. The big cloud providers aren't price competitive but Contabo/Hetzner really surprisingly are especially if you pay a lot for electricity. But then if you need a game server it can be quite hard to find good fast CPUs on the cloud and its not going to be 24/7 for communities, so the trade off flips back to having your own.
Since I got 1 gbit/s fibre internet my need for internal NAS has definitely reduced as the internet is nearly as fast as the local network so I could now have my NAS needs remote.

For me it does. I'm sure some other people use a VPS or something and self host using a cloud provider of some kind.
I pay Dreamhost for a beef pc VPS, that's what "selfhosted" means to me. I host all kinds of shit on it.
What kinda beef are we talking here?
500 GB SSD / 16 GB RAM / 8 vCPUs you won't go hungry
I do not think that self-hosting necessarily means that you have to host it at home. As others have pointed out, its more about hosting it on hardware you control.
I do think there is certainly a trust factor involved if you host stuff on hardware that you don't own, but at the end of the day only you can deem whom you can trust. For example, I rent a couple of dedicated servers from a provider, but I also have a pretty good personal connection with the owner of that provider - so I have no concerns about the safety of my data. In general, I tend to just be pretty conscientious about what data is going to any server, and anything that I wouldn't want falling into the wrong hands doesn't leave my house unless I can guarantee its safety (with the likes of encryption and such).
I do also keep in mind that with the various providers out there, reputation is paramount to them (or at least, the good ones) so it is generally in their best interest to say, let someone walk into their datacenter and just start ripping the drives from your systems.
Hey, I love this thread, and I am intrigued by the term "futureproof"ing. can someone direct me to a thread where local networks are self-hosted and the human element of organizing the network is discussed? Thank you. If I don't come back, it's because I'm new to Lemmyworld and got lost.
Running on a synology, but it's not cheap. I like having direct access to my stuff if I can. Next step is cloud backup of my local , i think borg or something is very popular.
I'm going to say that self hosting becomes a fun hobby once you get your core services running. Core in this case means the services that are bringing you into selfhosting.
at least i do have 2 servers. one main and one backup
I ran one for a few months until I woke up one morning and it wasn't working. As I was the only person using it, I didn't bother to troubleshoot and just signed up for an account at lemmy.world.
If you want to run your own I recommend you check out the ansible install route. It's really simple and straightforward once you wrap your head around ansible.
I consider selfhosting to be both. VPS or homelab. The latter has more 'cred' but is also a much bigger investment and not everyone can do it. Granted I'm living in a difficult environment but as somebody using Linux since 1994 it took me 3 years to recently get a homelab to where I could credibly serve the wider internet from it, and I still use a VPS as reverse proxy anyway! Meanwhile, offloading your physical plant to a mom-n-pop platform-as-a-service provider isn't the worst thing in the world. Some operators started out selfhosting and grew their little VPS provider from that, those guys need business too!
I don't know about the history of selfhosted, I use a vps at hetzner which serves as playground and I use a mini desktop (hp elitedesk) as my home automation lab.
This community is an inspiration on spotting new techniques and software to discover!
I have servers at home but I don't host services
I do the same. I have probably 20 VMs on my home lan. Then I have about 4 servers with various providers.
For me, since you can get kicked off a platform eg hetzner vps, it's not self hosted, they're hosting you.
