I've done my fair share of work helping out with botched cloud migrations. The reality is that it is absolutely essential to be intimately familiar with the platform you deploy with.

As long as you are in the business of deploying software, you have to know what you are deploying and how. You can call this person ops, devops, whateverops, or just the guy with most knowledge about Linux.

You are going to end up troubleshooting stuff, and the more far away you are from the hardware the more dependent you are on your tooling and the people who know how to use it. (Especially storage. Don't get me started on storage.)

Anyway, the point is that if you're going with Lambda then need someone who knows Lambda. They may be easier or harder to find than people who know Linux but don't wait until it's too late as that's going to be expensive. And conversely, invest time in learning the platform before you use it.
