Identity Service

An API authentication service that occurs when you access the services via the API gateway.

This service interacts with other services and authenticates, provides roles and permisssion to access the API.

Identity as a service comprises cloud-based solutions for identity and access management (IAM) functions, such as single sign-on (SSO). These methods allow all users (customers, employees, and third parties) to more securely access sensitive information both on premises and over the cloud.

Eg: A user can reach a certain service with certain roles and permissions recorded here.
