my go to strategy for zero downtime deployments is prob a blue green approach, tho its not always the easiest to pull

Hey everyone, I'm looking to start a discussion about the best ways to achieve zero-downtime deployments. We've all been there, facing the dreaded maintenance window. What are your favorite techniques or patterns for rolling out updates without any service interruption? Blue/green deployments, canary releases, rolling updates - what works best in practice for different scenarios? Curious to hear your war stories and preferred tools.
