Service-oriented development is older than most people realize. Yes, the notion of microservices is a relatively new trend; however, developers have used services for years to build applications and orchestrations out of existing services that you don’t develop or net-new services that you do develop.
It doesn’t matter if you call a service a microservice, a fine-grained service, a utility service (such as cloud storage APIs or services), or a common application API to access behavior and/or data. Leveraging services typically means that you use a service-oriented architecture that focuses on building applications out of new or preexisting components.
