## Intent
|
|
|
|
The user makes a single call to the Aggregator, and the aggregator then calls each relevant microservice and collects
|
|
the data, apply business logic to it, and further publish is as a REST Endpoint.
|
|
More variations of the aggregator are:
|
|
- Proxy Microservice Design Pattern: A different microservice is called upon the business need.
|
|
- Chained Microservice Design Pattern: In this case each microservice is dependent/ chained to a series
|
|
of other microservices.
|
