How would you do that on AWS? They can shut down your VM due to hardware failures on the host. The probability is low, but the impact may be large.

(1) They will usually notify a few minutes (or hours) in advance, and (2) it would take a few minutes to spin up and set up a new VM to replace the old, without leaving your terminal.

If budget allowed, I’d even spin up another region with DB failover setup too.

All the same architecture applies, the only difference is it’s done with K8S yaml instead of the CDK
