API Gateway is an API management tool that usually sits between the external caller (Web or Mobile) and the internal services. The API Gateway can provide multiple features like:
1. Routing
2. Request Aggregation
3. Authentication
4. Authorization
5. Rate Limiting
6. Caching
7. Load Balancing
ETC.

Ocelot is an ASP.Net Core (Supports .Net Core 3.1) API Gateway. It's a NuGet package, which can be added to any ASP.Net Core application to make it an API Gateway.
Ocelot API Gateway supports all the features that any standard API Gateway does.
I will cover the following features of Ocelot API Gateway in this video:
1. Routing (Basic routing to internal service)
2. Authentication (JWT Tokenbased authentication)
3. Response Caching (Using Ocelot.Cache.CacheManager NuGet package)
4. Rate limiting
