Introducing how Kubernetes will be used

Later on in the chapter, we will see in detail how various Kubernetes objects are used to deploy the microservices and the resource managers they depend on, like databases and queue managers. Before delving into all the details, let’s get an overview of the Kubernetes objects that will be used:

• For each microservice, database, and queue manager that will be deployed in Kubernetes, one Deployment object and one Service object will be created.
