I've built a startup on AWS, and same. Since we started about a year ago, I've gotten two "action required" messages from AWS.
One involved migrating our Go-based lambdas from the "Go 1.x Runtime" to a more generic one that AWS wants to use for compiled binaries across languages. They provided a very helpful guide, including the Cloudformation template changes. I implemented them, and they worked perfectly just as promised.
The other message I got was rather urgent and telling me I need to upgrade the SSL cert on my RDS. The due date on that action is August 22, 2024.
There are a few areas of AWS I've found to be pretty abandoned. (Don't try to send push notifications using the AWS Platform Application + SNS approach, woof.) But overall, I've been very happy with AWS as a developer.
Seems like a fair assessment. Maybe they should start by getting rid of the people who put that structure in place?
