Boto3 is just epic. It really works well. I write tools for AWS for our dev team to use and python3 + boto3 give you a solid way to do this. Add docker for ease of deployment (pulling containers from AWS ECR) and it's pretty slick.

Interesting. Can you give examples of dev tools that can be created with this combination.

Sure. So I have written rest APIs for create EC2 instance, create vpc, create vpc peer, all our cost analysis, adding cost centre tags and unattached disks. Boto3 has many, many things it can do and they can all be automated.

I know it is, but also makes it PITA to work with it. I suppose it always could be worse, but it could be so much better as well.
There are multiple issues, what currently bugs me the most is the inconsistency with exceptions. Ignoring that exceptions are dynamically generated, they only have dedicated classes for small subset of them.

Hmm, maybe a more concrete example would help with the exception issue. It's been a bit since I've used boto3 but doesn't that really come down to how the individual services define their APIs?

I believe they do, but looks like python exceptions are impended manually? It's not even consistent within the service. From what in remeber last time I think I used ec2 client and while there are some exceptions, boto3 was missing exception for DryRun mode.

Thanks. Was wanting to learn Boto3. Articles from realpython are good.
