Microservices


What are microservices?

Microservices represent a relatively new IT architecture pattern. A central term in relation to this is modularization: In contrast to the traditional, inseparable, and uniform monolithic architecture, microservices deals with the development of smaller, more flexible services. In order to establish complex applications, these smaller and independent processes communicate with each other via language-independent programming interfaces.

Differences between microservices and a monolithic architecture

Monolithic structures complicate handling when an application reaches a certain level of complexity. A monolithic solution is therefore often unsuitable for fast and dynamic development. The larger projects become and the more the number of people and modules involved increases, the greater the risks and disadvantages of a monolithic architecture become, because for a new release, all components have to be brought together as a single, large unit first – even those parts that have not changed at all. The flexibility of microservices is of particular benefit to companies that do not yet definitively know which end devices an application will run on when the development process is started. Due to the independence of platforms, applications developed with microservices are suitable for various delivery channels, such as the Web, Mobile, Internet of Things, or Wearables.
