🚀 Ocelot API Gateway Full Course | Part 1 (.NET Microservices)
If you want to become a high-paid Microservices Developer, API Gateway is a MUST.
In this video, you will learn:
✔ What is API Gateway
✔ Why Ocelot in .NET
✔ Microservices Architecture Basics
✔ Real-world use case
🔥 This is a ₹20L+ skill in today’s market!
This video (0:04-57:51) provides a theoretical overview of implementing an API Gateway using the Ocelot framework in a .NET microservices architecture. The instructor explains the fundamental reasons for using a gateway, core features, and architectural principles.
Key Highlights
What is an API Gateway? (2:53): It acts as a single entry point for all client requests (mobile, desktop, etc.), acting as a bridge between the front end and backend services. Its main purpose is to prevent exposing direct business logic APIs (private network) to the outside world (public network).
Core Scenarios & Features (3:23):
Security (4:20): Instead of implementing JWT authentication on every microservice, it is centralized in the gateway.
Rate Limiting (6:11): Protects backend services from traffic overload by limiting concurrent requests at the gateway level.
Caching (13:56): Improves performance by caching static data (like product lists) directly at the gateway.
Ocelot as a Framework (2:12): Ocelot is specifically a .NET framework designed for API Gateways in microservices. The process involves creating a middleware pipeline (25:59) for authentication, authorization, and rate limiting.
Upstream vs. Downstream URLs (36:26): The instructor defines Upstream URLs as the public-facing URLs (API Gateway) and Downstream URLs as the private URLs pointing to individual microservices.
Configuration (39:16): Routes are defined in a JSON file (e.g., `appsettings.json`) mapping upstream paths to downstream services.
Load Balancing (55:12): Ocelot also supports load balancing, which will be covered in future parts of the series.
