Understanding cloud design patterns
Patterns are low-level specific implementation guidelines that are proven reusable solutions for recurring problems. Each of the following patterns can be implemented in Microsoft Azure to build reliable, scalable, and secure distributed applications.

The gateway aggregation pattern aggregates multiple client requests targeting multiple backend services in a single client request, dispatches the requests to various backend services, then aggregates the responses received from all backend services into one response and sends it back to the client.
Usage
