Lets take the example of a heavily used cloud based software.
When a deployment happens, let's say users are online.
- Won't the server require stop & start after deploy? How is the service continuity maintained?
- How will the ongoing user sessions / unsaved data be continued post deploy?
- How is the risk managed? (Lets say an issue comes up after deploy and you need to revert to the older version, now imagine a user has already worked on the new version and saved some data with it, which is not compatible with previous versions)
