Securing Microservices using Identity Server 4

Welcome to "Securing Microservices using Identity Server 4" - second edition of Microservices Learning Series. The ultimate course for developers who want to learn how to build scalable, efficient, and robust Microservices using the .Net Core platform along with Docker, Kubernetes, Identity Server 4, Rabbit MQ, Angular 15, GRPC, Istio Service Mesh, SQL Server, MongoDB, PostGreSQL, Redis, Ocelot, Nginx, Azure, Helm Charts, and Auto Scale.

In this comprehensive course, you'll gain hands-on experience with Docker and Kubernetes to deploy and manage your Microservices. You'll learn how to integrate Identity Server 4 for secure authentication and authorization, Rabbit MQ for messaging, and GRPC for efficient communication between Microservices.

You'll also learn how to use Istio Service Mesh to manage Microservices traffic, and how to configure and optimize SQL Server, MongoDB, PostGreSQL, and Redis for your Microservices. You'll use Ocelot and Nginx to manage your Microservices API gateway and deploy your Microservices to Azure using Helm Charts.

By the end of this course, you'll have a solid understanding of how to design, develop, and deploy Microservices using the latest industry-standard tools and practices, including auto-scaling.

Welcome to the Identity Server 4 course, the second course in our Microservices series! This course builds on the foundational knowledge you gained in our first course, "Creating .Net Core Microservices using Clean Architecture", and focuses specifically on implementing secure Authentication and Authorization for your Microservices using Identity Server 4.

Identity Server 4 is a powerful and highly extensible open source framework that provides a complete solution for managing authentication and authorization in modern web applications and APIs. In this course, you will learn how to use Identity Server 4 to secure your microservices by implementing features such as:

• User Authentication using popular identity providers such as Google, Facebook, and Twitter

• User Authorization based on roles and claims

• Integration with your existing user database or user management system

• Secure token-based authentication using JSON Web Tokens (JWT)

• Secure communication between Microservices using client credentials and access tokens

Throughout this course, you will work on a practical project that will guide you through the entire process of integrating Identity Server 4 into your Microservices architecture. You will learn how to configure Identity Server 4, integrate it with your Microservices, and implement secure authentication and Authorization using the OAuth 2.0 and OpenID Connect protocols.

By the end of this course, you will have a solid understanding of how to use Identity Server 4 to implement secure Authentication and Authorization for your Microservices. You will also be able to apply these concepts to your own projects and take your Microservices architecture to the next level.

Enroll now and take the next step in your Microservices journey with the Identity Server 4 course!
