Benefits of the API gateway for microservices

There is no doubt that the API gateway is beneficial for microservices. With its use, you can do the following:

• Invoke services through the API gateway 
• Reduce round trips between the client and the application 
• The client has the ability to access different APIs in one place, as segregated by the gateway

It provides flexibility to clients in such a manner that they are able to interact with different services as and when they need to. This way, there is no need to expose complete/all services at all. API gateway is a component of complete API management. In our solution, we will use Azure API management, and we will explain it further in Chapter 3, Integration Techniques and Microservices.
