As I said, at least in the cases of your database and your storage, being cloud-agnostic is trivial. Managed postgres is easy to migrate from, S3 shouldn't be hard to migrate from either.
Certainly lambda doesn't impact this too much.
> Serverless technology is only starting out still and I'm pretty sure 5 years from now Lambda won't be the go-to platform anyway. Plus honestly we've learned so much from the first big project on Lambda that writing the next one with all of that in mind will be pretty great (and agnostic).
I realize it isn't entirely on-topic, but could you elaborate? I'm curious to hear more about your opinion on this, I'm not sure what the future of Serverless is.
Heck, consultants get paid lots of money just to do a lift and shift and migrate a bunch of VMWare images from on prem to AWS.
