Optimize deployment process for enterprise applications

If i have the previous deployment package generated using serverless package handy, is there a way only changed lambdas and new lambdas get deployed and the unchanged lambdas are skipped.

What would be correct way to go about this? What other things can I look at to optimize the deployment process for enterprise applications.

Couple of contracts ago I went into a place where it took about 45 minutes running it similarly to you (from code push, through AMI build in packer) to being live. Everything was fine, but there was a lot of pushing and pulling of images that wasn’t necessary, and we were building everything all in one go. (This was Django, Docker-compose, but no container orchestration).
