The ability to use Python as an API backend, which is very flexible for creating new functions with ease of deployment/maintenance via GitOps tooling like CircleCI or Codeship (or even just using git). It's easy enough that I can make changes in my editor without having it pushed straight into production yet powerful enough so you don't need super-expensive Devops staff at your disposal! We've solved our problems by allowing all developers access but not giving them full control over everything - we still have some fine tuning left regarding security controls etc., however this has been one step forward towards what was previously impossible from us before Mayascale came along :).
