Thoughts for microservices:
1. Any functionality that has a faster rate of change, newer implementations etc. can be a candidate for microservice. 
For example, inventory might not change but listing/aggregation services are scalable. So Movie Service and Movie Catalogue service 
can be different.
2. Independent scalability.
