New To Serverless

I ran into Serverless framework recently and I was wondering if customization needs to be done to use out of the box within a company AWS infrastructure? I noticed you have an Enterprise version but not sure if this is for a more advanced use case. The company I work for is beginning to build infrastructure around AWS and I am wanting to use SLS for a proof of concept project our team is working on. This POC consists of few services we want to write using serverless architecture, and I would like to explore using SLS for deploying.

Any comments or suggestions would be greatly appreciated.
