Only if you have been careful from the beginning to design your system in a platform agnostic way and don't rely on AWS specific services and APIs.

I'm guessing the biggest such service is S3. Other providers offer compatible APIs.

The fastest way to convince developers to abandon or avoid services is to start price gouging.

S3 is probably one of the easiest to migrate. More problematic would be things like SQS, SNS, DynamoDB, SES, Lambda, etc. And that isn't even mentioning any control plane or infrastructure level code.
