Small scale services were endured out of the need to scale rapidly while still keeping your code manageable. Netflix, Amazon, and Spotify are some of the interesting companies moving towards this type of configuration.

Microservice architecture is a process of designing software systems which distributes big software applications into many small services that can run individually. Each of the microservices has its individual team working on it, so they are fully separated from each other. This lets every service to run its own unique process and communicate independently without depending on on other services as a whole.

The idea behind microservices is that some types of applications become easier to build and maintain when they are fragmented into smaller pieces which work together like the containers. Each component is continuously developed and individually maintained, and the application is then simply the sum of its integral components. This is in contrast to a customary, “monolithic” application which is developed in one piece. A Docker is also one of the open source container software. Similarly an open-source tool like Kubernetes is used for automated deployment of containerized applications.


Microservices Architecture Characteristics

While there is no separate definition for the methods of Microservice architecture, there are some characteristics that can be comprehended the ways it is utilized.

  • Independently deployable and scalable
  • Made of smart endpoints and dumb pipes
  • Part of decentralized governance methods
  • Organized around business capabilities
  • Composed of decentralized data management
  • Autonomously developed
  • Evolutionary
  • Easily replaceable


Benefits of Microservices

Though some developers may be resistant to change, or hesitant about trying something different in their applications, the benefits of microservices balance the potential disadvantages. Microservices are exclusively beneficial for large applications, enterprise applications, and even various Internet software applications like:

  • Give developers the ability to independently deploy and develop services without waiting on results regarding the entire application
  • They can be built by a small team which has the independence to scale the services
  • The code can be written in multiple languages
  • They are structured around business capabilities
  • If one of the services fails, the others will continue to work
  • Only the essential service needs to be revised when a change is needed for the entire application

Although microservices allow you to set out changes rapidly, they require all clients of your service to be in sync with your releases. For more information email us at info@royalcyber.com or visit www.royalcyber.com.
