Microservices Use Cases Design

[stevehu]

So far we just have a use case to gauge the raw throughput and the latency of each framework under load. For real microservices, service to service calls are adding latency and it is a critical test. I am thinking about to implement several microservice patterns with database access involved. Currently, I am planning to implement two typical pattens.

Aggregator: A calls B, C, D.
Chain: A calls B, B calls C, C calls D.

All inputs are welcome and let's work together to design the use cases to cover majority business scenarios. Thanks.
