As a person from both devops and SWE worlds, it all comes down to "do you already know how." If you know how already, it's the way to go for sure. If you don't, the extra money to outsource it will enable you to focus on adding value elsewhere.

Now that said there's definitely a cultural belief in startups that you should outsource everything you can. It works for some people, but I've seen it kill others because they were sending all of their revenue to their vendors. The outsource model always suffers as you scale up.
