Getting Started with Reactive Streams

Over the years, application architecture has evolved. Businesses increasingly need to build systems that remain responsive and can scale when required. Systems should also be maintainable and quickly releasable. In accordance with these needs, we have started to build applications as loosely coupled services. We no longer build a system as one big application. Instead, we split systems into multiple independent, autonomous services. The objective for such services is to do one thing, and do it well.

In this chapter, we will discuss concerns associated with building such services. We will also look at how to address those concerns.
