I'm not versed in videogame network infrastructures, but wouldn't be enough just having a load balancer and a couple of instances to ensure "100% uptime"? At least before all instances and the load balancer itself decide to join a suicidal pact, but more instances mean less chance of a critical event happening, no?
At a press level, sure, and the same for the average user. Legally speaking these numbers do have significance, though. Amazon Web Services (at least at one time) offer a guarantee of 99.99% uptime for their infrastructure. That 0.001% covers things like once a year outages that make the news. A 10000th of a year is actually a tangible amount of time and not even Amazon is confident enough to ignore it.
Depends on the cloud provider. AWS, as an example, have up to three “availability zones” within a single data center. If the customer needs HA, they are encouraged to run their applications in separate availability zones. It means different subnets within the VPC, redundant LBs spread across those zones, and more.
There is also probably DNS-based global load balancing across different data centers.
That’s just the hosting infrastructure. I’m sure Chujo works on the office LAN as well. He might wear the infosec hat also, which means he’s up to his eyeballs in firewall policy.
I don’t envy my brethren in software development orgs. Been there, done that, got that t-shirt long ago.
