Microservice architecture is a way to decompose large monolithic applications into loosely coupled components, each responsible for specific, separate domain of your business.
Benefits of designing software in microservice approach:
1) Breaks down complex business logic into small, comprehensive parts, making it more accessible and understandable for the team.
2) Allows to manage (deploy, replace, update etc.) each microservice individually and independently.
3) Shortens time-to-market due to simplicity of every part, especially while reusing existing microservices in development of new products.
SIMPLE TO DESIGN
Designing system with microservice architecture divides into two simple steps – identify business domains to cover it with individual microservice, then drive them to resolve your business cases.
HANDY TO DEVELOP
Microservices use common API to collaborate, so each one can be created in different technology, enabling technological mixture and progressive evolution. In addition domains separation makes every microservice easy for project team to understand and labor new features.
QUICK TO DEPLOY
Architecture of low-weight and independent microservices enables frequent and fast deployment of new functionalities with no influence on other running applications. If needed, deployed microservice can be easily withdrawn and replaced.
GREAT TO MAINTAIN
Dedicated project teams can focus on simple microservices, which enables high understanding of business rules of specified domain, and, consequently, allows to gain ability to develop bug-free features faster, avoid accidental (non-business related) complexity.
EASY TO REPLACE
Each microservice can be replaced with any system which uses common API, and every system can be replaced by microservice.
EASY TO SCALE
It is easy to enable scalability in microservice architecture, which gives the opportunity to quickly multiply overloaded microservices, and reduce its numbers in order to cut unnecessary costs.
CREATED TO REUSE
Once created, microservices can be rearranged, modified and reused in order to shorten the time-to-market of new systems.
