Microservices architecture has been adopted by IT businesses around the world to improve turnaround time as demand for software grows. Microservices, in layman's terms, is an architectural approach to software development in which the software is made up of small, autonomous services. Each of these services can be created on its own.
Netflix, Amazon, Uber, and Etsy are all using microservices architecture to achieve new levels of scalability. Adopting microservices is also a straightforward approach. To construct a performant application, developers must choose the correct framework with all of the necessary integrated tools. In the long run, the framework chosen will affect the cost of development, ease of management, and maintenance.
There are numerous microservices frameworks with which to operate. To mention a few, there's Spring, Golang, Quarkus, Micronaut, and Ballerina. In this article, I'll explain why I think Spring is the best framework for building microservices apps.
What is spring?
Spring, sometimes known as "Spring Boot," was released in June 2003 and is one of the most popular Java microservices frameworks, with roughly 60.2k stars on GitHub. Spring Boot, which is powered by Spring Cloud, allows developers to create self-contained software components that provide your code more freedom. Because it is lightweight, Spring is regarded as a secure, low-cost, and adaptable framework that enhances coding efficiency and saves overall application development time.
Why one should use spring for microservices?
Uses Java POJOs
A POJO class is constructed to allow other Java programs to use the same objects. The main benefit of adopting a POJO class is that it eliminates the need for object creation redundancy in other Java apps. The get() and set() methods can be used to access the objects. When compared to heavyweight EJBs, the Spring framework uses Java POJOs, making it considerably easier to construct enterprise-class applications.
Dependency Injection
Instead of hard coding an object's dependencies, the Spring framework uses dependency injection to easily declare them via configuration files. Due to the fact that two classes are normally loosely connected in the Spring, this is feasible.
Aspect-Oriented Programming
Spring helps you to segregate business logic from cross-cutting issues. Concerns that cut over multiple portions of the application and influence the entire application are known as cross-cutting concerns. AOP attempts to address this issue by allowing us to express crosscutting concerns in "aspects," which are self-contained modules. For example, a security module's "aspect" can comprise "advice" that performs a security check and a "join point" that specifies when the aspect code should be executed in the accompanying application.
This can be done with either XML syntax or "AspectJ" syntax, which requires Java code.
Spring Architecture
Modular programming is a software development technique that divides a program's functionality into separate modules, each of which performs a specific task. Spring is organized in a modular fashion, allowing you to concentrate just on the components you need while ignoring the others. It is made up of approximately 20 modules. These modules include everything a developer needs to create enterprise apps.
Conclusion
The demand for excellent frameworks expanded as the industry migrated from monolithic to microservices architecture. Spring is a mature framework that has been around for a long time and continues to meet industry standards and provide capabilities that other frameworks do not. Because it was lightweight and backed by a large community, our organizations were able to use it to its full potential. Do you think another framework would be a better fit for your company's needs?
