Authentication and authorization and error handling and fault tolerance

We will learn about how to implement a robust authentication and authorization mechanism to secure access to your microservices and build fault-tolerant microservices that can handle errors and failures gracefully.

Authentication, authorization, error handling, and fault tolerance are critical aspects of building secure and robust microservices.

Let’s explore each of these topics in more detail.

Authentication and authorization

Authentication and authorization are fundamental security concepts in any software system, including microservices architectures. They are often used together to ensure that users and services are who or what they claim to be (authentication) and that they have the appropriate permissions to access specific resources or perform certain actions (authorization):

• Authentication (AuthN): Authentication verifies the identity of users or services. Common methods include...
