Awakening the view about Java microservices

Java Microservices has been a great boon for Java developers in elevating their business strategies. These services pave the way for developers to handle more complex data. Microservice architecture is a new kind in the web development industry. It gained a lot of popularity in recent years. The features and advantages of Microservices have attracted a lot of attention from business owners and product owners.

These microservices can adapt to the latest trends and technologies. Companies can switch to the latest frameworks and tools when they deal with particular components. Microservices enable the developers to build and support smaller parts that effectively upgrade on business demands.

Microservice is a demanding platform that can be employed on multiple servers that enhance the performance of the business. Microservice is preferred over monolithic architecture because monolithic applications consist of a single codebase, while microservices are generally composed of multiple loosely coupled services. A monolithic architecture is a traditional model for software development, which is specifically built as a combined unit, self-contained, and independent from other applications. In this write-up, we will get to know about the advantages and features of microservices. We will also get to know about the Java microservice architecture and the impact it could create in the business. Let us dive deep into microservice and get a brief knowledge about the tools and frameworks.

Trailing about Microservices and it’s benefits

Before getting to know more about Java microservices, let us get a clear understanding about microservices first. Microservices is an architectural and organizational approach to software development where the software has few independent services that communicate over a well-defined Application Program Interface (API). Basically, these services will be owned by self-contained teams. In microservice, each function serves as an individual service which enables it to handle a lot of users and is also quick to update. Microservices can also store data, since they are small applications with a finite set of dependencies. This enables the developers to scale services with help of  technologies like Kubernetes and Docker without writing any specific code.

Microservices have a huge demand in the market because of their features and advantages like flexibility, scalability, faster development cycle, and easier maintenance. The independent operation of service within microservice architecture enables the developers to introduce new components without initiating any downtime. The main feature of microservice is that if any service enters into a failure or fault, it doesn’t multiply across the entire system.

Moreover, it allows a small team to completely take over development, deployment, and maintenance processes, thereby reducing the complexities for the developers. It also enables faster releases because each service is independent, thereby reducing the time and risk across the entire application. It is much more cost-effective as the efforts are targeted to specific service management.

Architectonics of Java Microservice

Java microservice is an approach of developing software applications that includes breaking large applications into small, independent services. Developers make use of these services by performing specific functions and communicate with each other through a network using protocols like message queues or HTTP. The Java microservice architecture is a sequence of different architectural patterns like:

Microservices Architecture: Microservice architecture creates a set of small, independent, and self-contained services that work together to deliver the functionality of applications. Each service will be in charge of appropriate business capability, and services often communicate with one another through protocols like SMS and HTTP.

Service Registry and Discovery: It is a centralized database that keeps track records of all the services that are available in the system, along with the network location. Unlike the microservice architecture, there is no particular push to discover each service in the service registry and discovery.

API Gateway: It is a server that needs to discover each other’s services effectively. It assists as a single entry point for the clients and also a unified interface to access multiple microservices. The gateway handles rate limiting, composition and routing of requests, and security as well.

Event-driven organization: An EDA is an integration model developed to publish, process, and capture events across distributed systems in real-time. When an event occurs in an application, the message will be sent automatically to all other applications, so they can act on it accordingly.

Circuit Breaker: The circuit breaker is a design pattern that prevents network or service failure from spreading to other services. It is a safety net that detects failures and it temporarily blocks requests to the affected service. This makes the system function properly while the bug is being fixed.

Elegancy of using Java in Microservices

Several tools, frameworks, and libraries can be implemented by the developers in microservice architecture. The main reason for preferring Java for microservices, it guides the developers to create and ship applications faster, improve scalability, and also adapt to the current business demands. Java provides a lot of frameworks that enable the developers to make the microservices work simple and fast. SpringBoot, Jersey, DropWizard, and Spark, are some of the Java Microservices used by the developers for their developing purposes. Moreover, it also has a large community of developers with a wide collection of libraries, resources, and frameworks. Java mostly relies on JVM allowing developers to create more complex applications, cloud-based applications, etc.

Java also possesses simple illustrations that are easy to read and also developer friendly. Java Enterprise Edition standards support microservice architecture like Java Persistence API (JPA) for data handling. The Java application development is organized in a way that is developed to support the creation and implementation of microservices. The main reason for preferring Java microservice is that it offers a lot of advantages like system robustness, enhanced user experience, and it boosts the performance by providing better response to the changing workloads. It also enables the developers to develop and launch services independently and it simplifies the migration and deployment plans.

Highlighting Microservices Frameworks and it’s advantages

A Java framework is the body of predefined codes used by developers to build and develop applications on the web. Classes and objects are the frameworks in Java development that help in hardware control, process input, and also communicate with the system applications. The Java microservices framework plays an important role in business growth and development. There are several key frameworks used in Java microservices such as SpringBoot, Quarkus, MicroNaut, Helidon, etc. These frameworks make the services more scalable, flexible, and also easy to maintain. Applications developed with the help of these frameworks consist of small, independently portable services that communicate with each other through services.

SpringBoot is the most popular framework used for developing Java microservices. SpringBoot simplifies the development process by generating a ready-to-use framework. It has excellent support for integrating with other technologies like supporting systems, databases, and cloud platforms. Similarly, MicroNaut is another framework used particularly for developing cloud-based and serverless applications. It is designed in a way to easily develop a service and it also has strong support for serverless functions.

Moreover, it provides Ahead-of-time (AOT) compilation that precomputes everything the application needs at compile time. This results in faster start-up times and lower memory footprint, enabling it to frequently start and stop the services. Quarkus is used to make Java a leading platform in Kubernetes and serverless environments. This offers the developers a cooperative and imperative programming model.
