How to execute efficient communication for multiple (micro)services?

问题

Case: Software build with many microservices and internal services.

The doubt is how to manage performance issues (network latency, size of resource) getting multiple resources from many microservices at once.

I Just can not imagine making 20 HTTP requests to access all necessary resources.

In order to reduce the number of requests made you might create a facade that encapsulates incoming API calls. This enables you to get rid of expensive network roundtrips.
