Microservices in Spring Boot, a Screencast

In software development, the term microservices refers to many independent services communicating with each other over an API. In a microservice architecture, these services must exchange information in order to perform complex tasks, and each communication is a point of vulnerability, and potential latency.

This Spring Boot tutorial screencast demonstrates many of the critical functions how microservices communicate with each other, including how microservice architectures use tokens:

Creation of private/public key pair

Registration of public key from one service to another service

Creation of JWTs signed with private key

Verification of JWTs using public key

Example of Account Resolution Service using signed JWTs
