my strategy for zero-downtime deployments involves a few key things, and honestly it's all about planning.

hey everyone, i'm trying to figure out the best way to deploy new versions of our services without interrupting users. we've looked at blue-green deployments and rolling updates, but each seems to have its own set of challenges, especially when dealing with stateful services or complex dependencies. what approaches have you found most effective in practice, and what are the key gotchas to watch out for?
