API Gateway using Ocelot

Hi Friends,

In this section, we are going to see how to build API gateway using Ocelot. Ocelot is one of the most popular libraries for API Gateways used in conjunction with Microservices project. In the last article, we have seen how to handle the traffic using envoy gateway. In this case, we are going to extend the same example using Ocelot and see how it works underneath. As we know already, Gateways are very useful and it helps with following features seamlessly.

  • Routing
  • Authentication
  • Authorization
  • Rate Limiting
  • Caching
  • Load Balancing
  • Circuit Breaker
  • Request Aggregation
