I had that kid-like wonder at a recent project where I had to re-architect an Amazon-hosted website for a customer.

It took me back to that childhood experience of playing with Lego. Everything just "snaps together", and a lot of things that ought to be difficult were shockingly easy.

Mid-way through the project the customer apologised because they forgot to mention that they needed geo-redundancy for every layer, including the database.

It was a checkbox on AWS Aurora. A literal checkbox. I pressed it. There was a progress notification and then it was done. Just like that. A distributed cluster.

I know what's involved, it's not like I haven't built SQL Server clusters dozens of times before, I've even scripted the process before. But it's kind of magic to see it condensed down to a the absolutely most trivial true/false button that it could possibly be.
