Datadog is good for metrics, but I'm more curious about the deployment side of things. For example, let's say I just made an update to a service's API that requires deploying new versions of 3 microservices. I want to (1) be able to locally deploy and test the 3 new versions, and (2) deploy all 3 versions at the same time. This ends up being super tedious because I have to do a lot of manual work just to push a (potentially minor) update.
