Curious to know how many people do zero-downtime deployment of backend code and how many people regularly take their service down, even if very briefly, to roll out new code.
Zero-downtime deployment is valuable in some applications and a complete waste of effort in others, of course, but that doesn’t mean people do it when they should and skip it when it’s not useful.
For our batch workflows, we do have downtime on deploys. It’s by design because 0 downtime doesn’t add any value. Downtime is usually 5 to 10 minutes. For our services, we rely on lambdas or kubernetes rolling deployments so no downtime.
