Absolutely but most of the knowledge translates, it's the procedures that differ.

It's those different procedures that I'm trying to avoid. It's not that I couldn't do those things or learn to do them, it's that my time is best spent building and improving our applications, not keeping servers running, secured, and up to date.

At some point we hope to get to the scale where it makes sense to pay a human to do that, but at this point the additional cost incurred by an ECS instance over an equivalent server is negligible.
