Microservice is a buzzword in the software industry. All around the world, businesses are migrating their systems from monolithic to microservice architecture. But, what are microservices? How do they work? This detailed guide will walk you through everything you need to know about microservices.
What are Microservices?
Microservices Represent a design approach to build a single application as a suite of small services, each running in its process and communicating with each other using lightweight mechanisms. These services are independent and deployable by fully automated deployment machinery.
Key Features and Components of Microservices
1. Decoupling
Project teams can make decisions independently of one another due to decoupling.
2. Componentization
Microservices can be created and deployed independently from one another.
3. Business Capabilities
This is your business domain, which outlines the capabilities of your organization.
4. Team Autonomy
Each team gets the freedom to pick their own tools and technologies.
5. Continuous Delivery
The constant pipeline of development to production.
6. Responsibility
Each microservice has a specific job and it is responsible for that.
7. Decentralized Governance
It is a system in which decisions are made from the ground up.
8. Agility
Flexible and easy to manage.
Benefits and Drawbacks of Microservices
Microservices have several benefits such as self-containment, independent deployment, improved performance, easy testing, scalability, simplicity in debugging & maintenance among others.
However, it is worth noting that microservices also have several drawbacks like complexity in testing and monitoring, lack of the proper corporate culture, high costs, security implications, and the difficulty in maintaining the network.
Real-Life Applications of Microservices
Microservices architectures replaced monolithic architectures for most large-scale websites like Twitter, Netflix, and Amazon.
Tools Commonly Used In Microservices
Some of the popular tools used in microservices include Wiremock, Docker, and Hystrix.
Spring Cloud and Spring Boot
Spring Cloud provides a suite of tools for developers to quickly build some of the common patterns in distributed systems while Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”.
Other Key Concepts
In addition to the general knowledge about microservices, it is also vital for developers to have knowledge about other related concepts such as OAuth, Domain Driven Design (DDD), Reactive Extensions, Docker, etc. A clear understanding of these concepts not only enhances the development exploration but also helps to deal with microservices effectively.
The Role of Docker in Microservices
Docker is a platform that developers use to automate the deployment, scaling, and management of applications. Docker epitomizes the saying, “Build once run anywhere.”
In conclusion, microservices offer a new way of building applications for businesses looking for scalable, agile, and robust systems. The migration to a microservices architecture might be challenging but the benefits are worth it.
