Ask HN: How do you deploy your websites?

We currently have an ansi or script tied to a database of sites & git hashes. This is then run as a task to deploy to aws auto scale or individual servers (depending on site).

We are at a position of changing our hosting and deployment methods and interested in other peoples approaches.

Ideally we would have something that can rollback, automate any composer or on-server tasks (clearing cache etc)

We might be getting our own physical hardware and then VMware if that helps.

Thanks
