It’s as if an entire generation of tech workers are utterly unaware that these have been solved problems for decades.
You put two machines behind HAProxy with keepalived. If you want to do a new deployment, you can spin up new machines in the same manner, and cut them over (or any of the many other ways to accomplish this).
AWS isn’t inventing any of the HA stuff they offer; they’re taking existing technologies and packaging them.
- valenterry 2y agoSo how do you do all of that with "a raspberry pi or mini PC"? You would need at least 4 of them.
- sgarland 2y agoI was replying to your comment, not the other. But sure, get 4 RPis if you want. You could also be using containers on them, and not need to swap whole computers. Or run each app in its own chroot jail. Or run VMs. There are many, many ways to accomplish this goal.
