What are Microservices?

Microservices Defined

Microservices define the latest iteration of a service-oriented architecture, under which applications are not written as a monolith but are built by joining discreet components — bits of functionality, called services — via application programming interfaces (APIs).

Among the advantages microservice architectures provide are the ability to iterate more quickly, by having teams work on these individual application components, speeding both bug fixes and the introduction of new features. These microservices are deployed via containers, which can be taken down from an application, amended, and plugged back in without causing the entire application to come down.

 

While the benefits of microservices are clear, having so many small pieces of functionality used to compile applications creates a security issue. The more services you run, the more surface area hackers can exploit. Microservices also create problems because often, organizations don’t know who created a service, or what will happen to their application if the service changes before they are aware of the change. Then there is the enormous issue of managing so many small, moving pieces.
