Microservices is an architectural pattern used for building large and complex apps. It breaks down the large app into various small, independent services. Each microservice is loosely coupled with others, which allows communication between them and maintains the functionality of the app.
Nowadays, the best software development companies leverage this pattern to deliver scalable and secure enterprise applications. However, to succeed, you must also have the appropriate microservices tools that help in building and managing microservices.
This article discusses the best microservices tools that you can use for your project.
1. What are Microservices Tools?
Software programs that simplify the task of developing, deploying, and maintaining applications with a microservices architecture are known as microservices tools. Developers leverage them to manage crucial tasks like handling configurations, distributing load, and discovering network applications to improve the efficiency and stability of the microservices environment.
Microservices use APIs to share features. Software components can communicate using APIs. For example, the streaming services from Netflix are handled with an API gateway.
However, not all APIs are microservices, as they imply an approach to app development. Meanwhile, other APIs such as REST APIs focus on communication and design principles.
