TL;DR: Slack notifications of deployments, app starting, data exports, etc.
Slack is an interesting communication tool with a lot of features and a plethora of extensions to further expand them.
In my opinion, the neater of them are the integration of third-party platforms. Take Atlassian for instance, with an extension it is possible to receive notifications whenever a JIRA ticket is updated.
Unfortunately, microservices don't get the same attention. They are left alone and developers usually have to be connected on them (using the all migthy SSH) to known what is going on. And we all know how lazy they are.
