Ask HN: Any resources on how to move existing premise applications to cloud?

When tasked with moving an in-premise application to cloud based one, what are the things to be taken considered?

Some of the things I can think of

* re-architect the existing app probably to micro service architecture (debatable)

* how to setup CI/CD process

* processes and tools

* how to auto scale with not only on AWS/Azure but own data centre

* monitoring and logs

Of course, I might be missing a lot of things from the list above.

I would like your suggestions on going about this. Any pointers to any resources (books, videos, articles, etc ...) highly appreciated.
