Microservices Demo | Building Microservices with .NET Core C# | Ocelot API Gateway | Sukhraj

Microservices is a new software architecture. It is based on the Web Services (Web APIs). Microservices are the architectural approach to build applications from small to large scale applications.

An API gateway is an API management tool that sits between a client and a collection of backend services.

Ocelot is a lightweight, open-source, scalable, and fast API Gateway based on . NET Core and specially designed for microservices architecture. Basically, it is a set of middleware designed to work with ASP.NET Core.
It has several features such as routing, caching, security, rate limiting, etc.

Thanks for sharing, Your video is more helpful to me. Could you please make one more video handling large project with ocelot and different-2 environment like dev, UAT and QA how manage?.

[personalaristobulo]

Great video! Do you happen to have information on deploying to IIS? I'm currently running some tests, and I can't seem to get it to work

[harshkadam]

Hey hey please please tell me how did you add microservices to this solutions

[backendb.]

The httpDelete method cannot be accessed through a URL, Accessing through URL makes it the HttpGet method, otherwise it is informative

[siddharth]

What if I need to pass json body to post request?

[salmangetify]

Awesome brother.. can i get source for this to understand better

[thejass]

You have used httpdelete not httpget for productversion endpoint 😅
