Reactive is a software architecture style for managing dataflows and providing resilience and elasticity for applications at the system level. It’s based on the Reactive Manifesto and can be implemented using a variety of tools.

Reactivity is the ability of a substance to respond quickly and in the appropriate fashion to external influences, such as heat, light or other chemicals. This is important because it affects how the substance will behave in a given scenario. For example, corn starch is inert if it is left on a shelf, but once mixed with water and vaporized to form a cloud, it can readily react by releasing carbon dioxide gas and sodium acetate.

It takes energy to rise above a challenging situation and take a proactive approach. This energy is required in order to prevent the situation from spiraling out of control. For example, it takes a lot of effort to remain calm in the face of a difficult boss or when your stock goes down after you’ve invested your hard-earned cash. Developing proactive behavior helps you control what happens to you and leads to a better quality of life.

Reactive Programming is one tool that can help you build a Reactive Application, but it only addresses dataflow management through asynchronous and non-blocking execution. The real challenge is how to construct a Reactive Application at the system level, with features such as resilience, elasticity, mobility and location transparency – especially when dealing with distributed systems with a large number of services. This requires more than simply abstracting away OS-specific resources and sprinkling asynchronous APIs and Circuit Breakers across your existing software stack.
