Service-to-service authentication

Let’s get started with service-to-service authentication!

Problem

How to onboard and authenticate services for a cloud-deployed application.

Context

Apart from users, systems and services interact with cloud resources and cloud applications to deliver functionality. There is a need for a standards-based approach to be able to implement effective and efficient service access to applications in the cloud.

Traditionally, security is enforced at the edge layer for a monolithic application, and subsequent interactions are considered secure. This is like an entry check at the gate of a mansion, and then no authentication is required to enter different rooms of a building. But in cloud-based applications, there are multiple microservices, and they need to communicate with each other to deliver the function. Authentication is required at each service entry point. This is like an identity check for entering each room in the mansion. These...
