Mention some benefits and drawbacks of an API Gateway

There are some:

• A major benefit of using an API Gateway is that it encapsulates the internal structure of the application. Rather than having to invoke specific services, clients simply talk to the gateway.
• It is yet another highly available component that must be developed, deployed, and managed. There is also a risk that the API Gateway becomes a development bottleneck.
• Developers must update the API Gateway in order to expose each microservice’s endpoints.
