Software developers can use several methods when creating their web projects. One of them is called microservices. This is by no means a new approach, which implies using several modules (services) to create a new service or program. The idea of this IT architecture is that it is possible to change the program code at any time without damaging the already ready and successfully functioning elements.
Active implementation of this approach in the IT-sphere began in 2012. Since then, it has been used mainly by large companies. For example, Netflix has also been using microservices on AWS architecture for several years. Microservice Application Development is relevant for different businesses: online stores, manufacturing companies, delivery services, IT, and others.
However, this development approach will not suit all services: the application must be complex enough and perform many functions to be broken down into components. Microservices allow you to create web products with easy scalability, decentralization, continuous delivery, and fault tolerance.
Features of microservices architecture:
- Isolation of individual modules during failures;
- Unlimited scalability;
- Ability to combine several complex services in a single subsystem.
Beginner developers may misinterpret this concept (MS). Each module in question is a part of a program code that can be changed or replaced at any time without damaging the integrity of scripts and so on.
Microservice technology allows you to create applications that are optimized for DevOps and CI / CD. Without microservices, any change in the program’s uniform code demands transfer in an independent mode and check after the made changes (QA). In the case of update only separate modules, it is unnecessary to stop all services or make changes in all program code. Microservice architecture, in most cases, works in the cloud environment for fast data exchange. This development of technology is continuously linked to cloud services.
This technology is convenient both for small development teams and for large companies with developed IT infrastructure. Imagine that using MS allows individual groups of developers to work on different tasks without interfering with each other and without stopping the whole service or program.
Many companies have already successfully integrated MS architecture into their activities, but it did not start right away. If you need to work with one service or application, it is more rational to start with a monolithic architecture. Then, only as the load grows, new functionality becomes available, the number of users increases and you can switch to MS, which will accelerate scalability and provide painless service even in the event of failure.
In addition to the advantages described above, we can highlight the convenience of deploying such an architecture in companies. Through API-interfaces, developers can independently choose the language of the code for writing certain functions of programs.
Please note that professionals should do development using this technology. Although this technology is elastic, scalable, and stable, it is necessary to perform testing, correctly function deployment, synchronize several services into a single whole. It is very difficult to start deploying such systems independently, so even large companies hire specialists to implement microservices in development.
