Hands-On Microservices with Spring Boot and Spring Cloud: Build and deploy Java microservices using Spring Cloud, Istio, and Kubernetes

by Magnus Larsson

Faster development, enabling continuous deployments Easier to scale, manually or automatically

A microservice is essentially an autonomous software component that is independently upgradeable and scalable.

It must conform to a shared-nothing architecture; that is, microservices don't share data in databases with each other!

It must be deployed as separate runtime processes. Each instance of a microservice runs in a separate runtime process, for example, a Docker container.

Microservice instances are stateless so that incoming requests to a microservice can be handled by any of its instances.
