Microservices

What are microservices?

Microservices describes an architectural concept in the field of application development. Although they form a software framework, they are loosely coupled with each other so that the development and deployment of each service or function can be implemented independently. Changes or disruptions of one service do not affect the rest and, accordingly, do not cause the entire application to stop working. And this is also the difference between microservices and traditional monolithic software architecture approaches.

What are the benefits of microservices?

Agility

The independent architecture allows the formation of small development teams, each focusing on one service and working within a clearly defined context. This enables projects to be realized independently and quickly, and shortens development cycles.

Flexible scaling

Each service is independently from other services scalable. So it is not only possible to sustain each service when there is an increase in demand, but teams can also accurately measure the costs of a function and adjust infrastructure requirements.

Easy deployment

Microservices make it possible to continuously integrate new services or provide new applications. This makes it easy to try out and discard new concepts or ideas. Since the costs of failure are low, microservices favor these experiments, facilitate code updates, and shorten the time-to-market for new concepts.

Technological flexibility

The microservice approach allows users to freely select and assemble the software modules that are necessary for the best solution of a specific task. In this way, the most suitable software module (tool) on the market can be selected for each specific problem and the best possible result can be achieved.

Reusable code

Through microservices software is divided into small, separate modules with their own functions. However, the code that was written for a particular function can be reused as a building block for other functions. This allows developers to use a building block without the need to write code from scratch.

Resilience

In conventional monolithic software architectures, the failure of one component usually leads to the failure of the entire application. Microservices, however, have service independence and thus avoid a complete failure, since only the respective function is affected, but not the entire application.
