As the digital transformation enters the deep water area, the demand for enterprise application program construction increases rapidly and changes rapidly. The software architecture has experienced single structure, vertical architecture, SOA architecture, and developed to the current microservice architecture.
The monolithic architecture is currently widely used and easy to deploy, but the monolithic application contains all the required services, and each service function module has a strong coupling, that is, they depend on each other, making it difficult to split and expand. The maintenance efficiency is low and difficult, and a lightweight microservice architecture is urgently needed to solve the pain points of the application architecture of the enterprise's digital transformation and quickly respond to the business needs of the enterprise's digital transformation.
The so-called microservice architecture is a method of developing a single application as a set of small services, splitting an application into multiple loosely coupled services, allowing the services to cooperate with each other through a certain protocol, and completing the original single architecture functions, reduce the coupling of the system, and make product delivery easier and more flexible.
The purpose of the microservice architecture is to reduce the complexity of the system through business splitting, and to provide reusability through service sharing. These services are built around business functions and can be deployed independently through a fully automatic deployment mechanism. These services require minimal management, can be written in different programming languages and use different data storage technologies. The agility of business support is achieved through service-oriented; the barrier of data interaction is eliminated through a unified data architecture. The application of microservices is committed to loose coupling and high cohesion: using a separate business logic package, accepting requests, processing business logic, returning responses, and ultimately achieving agile development.
In order to stay ahead, business units need to maintain high-speed development, and introducing new technologies or methods often requires rewriting the entire application. Microservices split applications into small, loosely coupled services by function, which can be reused in different projects, and can be scaled horizontally, have definite module boundaries, and use multiple technologies for parallel development, requiring less Production time. As a result, developers can work faster and update applications quickly.
The functions of the application often have different expansion requirements, and the content built by different members is intertwined. It is difficult for each member to be responsible for the design, operation, and maintenance of the content built. Developers of microservice architecture can run services in the most suitable environment. By splitting applications into smaller services, small agile development teams can focus on smaller functional points, faster and at a higher Quality develops independent features.
These teams can use it with the main development methods as well as DevOps. Team members can easily and quickly maintain services and be responsible for the services they build to improve the process and meet the needs of each service's expansion and resource usage. Easy to use microservices architecture to reduce internal politics and other issues that can delay deployment, making IT teams across the enterprise more effective.
In short, microservices improve the high-performance and high-concurrency capabilities of application systems, and greatly increase system throughput. They also shorten system development cycles and improve development efficiency to a certain extent. They are a sharp tool for enterprise application and data transformation and upgrading, and are also digital transformation and an indispensable midwifery tool for operations.
