Securing Microservices with OAuth2 and Spring Security

An Overview of Implementing OAuth2 and Spring Security to Enhance Microservices Security

Hello folks, as Microservices architecture become more and more popular in modern application development particularly in cloud, ensuring robust security becomes a critical concern. It’s also one of the popular Microservice interview question which is often asked to experienced programmers and developers.

One common approach to securing microservices is by leveraging the OAuth2 protocol in conjunction with Spring Security, a powerful and widely used security framework for Java applications.

Security is also one of the main concern while designing Microservices as mentioned in my earlier article, 10 things to keep in mind while designing Microservices.

In the last few articles you have learned popular Microservice design patterns like Event Sourcing, SAGA, Database Per Microservices, API Gateway, Circuit-Breaker, and CQRS and also learn about the best practices to design Microservices and in this article, we will explore the concept of securing microservices using OAuth2 and Spring Security.

We will also delve into the fundamentals of OAuth2, understand how it works with Spring Security, and explore best…
