What’s the Best Way to Deploy AWS Lambda Functions Quickly?

I've had good experiences with AWS SAM for smaller projects. It definitely helps simplify things like IAM permissions and overall management.

I started using Terraform but found it to be a bit slower compared to SAM or CDK for Lambda functions. However, if you're working with larger services, it can still be a good choice depending on your needs.

I've been using the AWS CDK lately, and I think it's a solid choice. It can be a bit cumbersome at first, but it gets easier over time. Pairing it with projen also helps keep your code organized, so it's definitely worth considering.

For an alternative approach, I've been using ECS with Fargate combined with Go, which works really well. If you need to stick with Lambda, using CDK or Terraform with Go gives you a scalable setup.

When I'm developing, I run my code directly from the IDE, and honestly, it's the fastest way to test things out without having to redeploy.
