The Need for writing the microservice applications in Java

For excellent reasons, Java is a common linguistic option. The language is strong, with years of experience working with critical apps for missions and evolving with the emergence of fresh planning models. The near-omnipresent use of Java in company apps has developed an extensive pool of Java-based software developers. Even when fresh apps are created, it is useful to use current abilities.

The intensive learning curves are provided by microservices with the addition of a language to the mix which may increase the danger. It presents yet more unidentified information about the creation, deployment, and administration of a manufacturing microservice implementation.

To revolutionize your organization, it’s always positive to keep an eye on the upcoming technologies, frameworks, languages. If in your monolithic framework you are still cemented in your cube messing around with code, then you probably live in the past, where you have a small application and some employees to handle it.

JavaScript is usually used for the application front end (particularly for web-based applications). Java for battle-tested data management is also common in the background. While there is still a lot of space for spectral variations, Java is great for writing micro-services.

Nowadays, things have been changing. You have to go a step forward and walk with the revolutionary technologies where microservices are among the leaders. Are you looking for the best reasons to invest time in learning microservices with a view to becoming an architect and developing applications using them?

This article will help you in learning various advantages of microservices architecture and various reasons so as to why learn microservices.

  • Various Tools can be used flexibly as and when required

The architecture of microservices encourages the use of the most suitable technology for the service’s specific needs. Each service is free to use its own language, framework or auxiliary services. The services still communicate easily with the other services in the application even with the use of such diverse frameworks.

 

  • High-Quality code is provided

The entire framework is modularized into discrete components following the microservices architecture. This helps the application development team concentrate on one specific job at a time. In turn, this simplifies the overall process of coding and testing.

 

  • Various Applications can be easily Built and Maintained

The team of developers divides into the following activities as and when the products built by developers become stable and are available for customers.

  • Implementing various new features
  • Bug fixing
  • Modifications in the existing features

If the product is based on a monolithic framework, each change to the codebase must pass through all stages of construction, maintenance, and deployment. Microservices are a savior in these situations!

 

  • The Technology Stack

The technology stack is difficult enough to decide for a monolithic application, but for every microservice, this decision must now be taken. What seems theoretically attractive can become difficult in practice if your services are too heterogeneous. Standardization is becoming a problem and cowboy behavior is possible. It’s also more difficult when every team has a totally different stack for people to move between teams.

It is always recommended to have a balanced approach where the application has a preferred technology stack. If any team wishes to override this default stack, it should justify the fact that it is better suited for microservice with advantages and disadvantages. Your stack of technologies should include the language of programming, test, and logging, cloud providers, facilities, storage, monitoring, etc.

 

  • Improvements in the Scalability

The main aspect of microservices is scalability. Since each service is a separate part, a single function or service can be expanded without the application being scale-up in full. Business services for increased availability and performance on multiple servers can be used without affecting the efficiency of other services.

 

  • Faster Market Time

Due to the fact queuing up of microservices, you don’t need to rewrite all the codebase for a feature to be included or modified. Only a specific service will be changed. You can quickly market your application and services by the development of applications in smaller increments that can be independently tested and deployed.

 

  • The Complex Operations

The complexity of operations is much increased by microservices as operations must be revised from a fundamental point of view. The following aspects must be considered:

 

Infrastructure

The definition of microservice infrastructure requirements and subsequently the provision and maintenance of infra for each microservice creates a level of complexity which most monolithic Ops engineers are not used to. Furthermore, as these services are expanded and reduced, the infrastructure must be automatically provided and reduced, thus requiring a very advanced level of automation.

 

Load balancing and scaling

It is likely you will need a much more complex, scaling strategy than with monolithic, ever-scale(x-axis) applications. If you need to scale all the services or just a subset when there’s a high demand, you’ll need to figure out with Microservices. The y-axis scaling is essential for the operations team, as the microservices approach and z-Axis scaling are consistent to obtain x and y.

 

Service detection

Dynamically, due to scaling and upgrades, the set of service instances of a world with microservices. Services also have dynamic network locations, so you need a way to discover new services. For this, it is always recommended to go for a registry service such as Consul because it works very well.

 

Monitoring

This must be configured and maintained on every microservice to make the operations team engineers more complex. In addition, the surveillance solution must manage situations for increasing and downloading a subset of facilities.

 

  • Delivery is Continuous

In contrast to monolithic apps where devoted teams operate for each individual function like database manipulation, server logic retention, microservices utilizes the continuous delivery model to manage the entire application lifecycle.

The developers, the test teams and the operations team work together on the construction, testing and debugging of a single service.

 

  • Risk Reducer

Every service in the microservices framework is a distinct entity, which enables localization, increased confidence in quality, and end-to-end regression scenarios. Even if one service or application element is down, the entire application will not decrease. Rather, the designers only need to rebuild that specific service or element. This decreases the danger of your company application being completely dropped!!

 

  • Delivery is Continuous

In contrast to monolithic applications in which dedicated teams are working on discreet functions such as UI, database, server logic and technology, microservices employ cross-functional teams to operate on a continuous delivery model for the entire life cycle of an application. Testing and deployment become simple and instantaneous when developers, activities and test teams operate on one service concurrently. Code is constantly being created, tested and implemented through this strategy of incremental development, and instead of reinventing the wheel; you can use code from current libraries.

7 tips to become a better JAVA developer

How to become a JAVA Developer 

A lot of people know Java the programming language. What these people don’t know is that merely knowing this programming language is not going to be enough for you in the long run. You need to be very proficient in Java programming and coding if you aspire to create a functional and feasible application. Sitting around with the same level of knowledge is not going to help your case one bit. You can try to polish yourself more in Java programming if you wish to be the best Java programmer.

Java is simply the most popular programming language. A lot of Java developers are already there who have a good knowledge of the recent trends in technology with the willingness to learn the latest developments of Java, which include Java 8, JVM and also JDK 10.

If you want to get hired in a Java development company, you will have to present a considerable amount of difference when it comes to efficiency and skills from your end. 

Read on to know the 7 best tips that can help you become a better Java developer:

java developer tips

1) Learn JAVA 8

There are a lot of Java developers who are backed up with an experience of about 6 or 8 years, but still, they have not got to terms with using features of Java 8 like Lambda Expressions, different default methods and the Java Stream API.

If you can get a good grip on these features of Java 8, you already are ahead of the competition.

2) Good knowledge of Java API and libraries

Being one of the most solid programming languages out there, Java has the second biggest Stack Overflow community, which outlines a crucial role in the development of the entire Java ecosystem. Java APIs and Libraries constitute a big part of the ecosystem. Knowledge related to vital APIs and libraries, third-party libraries, and Java Development Kit is considered as an essential attribute for a good Java developer.

While the knowledge of every single API and all elements in the library is not expected from a Java developer, the refinements regarding crucial APIs and libraries should be there for sure.

 

3) Learn Spring Framework (Spring Boot)

Now, this is a platform that is essential for you as a Java developer without a doubt. The Spring framework allows a developer to create applications from some pretty old Java objects and is also very useful in Java SE programming as well. Most Java development companies take the help of Spring framework like Spring MVC, Spring Cloud, and Spring Boot to develop a web application and REST APIs.

A good Java developer is also aware of the advantages that the Spring framework offers such as making local Java methods a remote process and also make Java methods execute within a database transaction.

 

4) Refine your Unit Testing skills

Advanced unit testing skills are to be found in every conditioned Java programmer. This is an essential factor that separates great Java developers from ordinary ones. As a professional Java developer, you should always write unit tests for your code because it helps in the validation of the code at the time of behavior testing or state testing.

Most companies today make sure that as a Java Developer, you have an understanding of the different tools used for automation testing, unit testing, integration testing, and performance testing. 

 

5) Focus on JVM Internals

Even as a beginner in Java, you are expected to know Java Virtual Machine (JVM), a critical factor of JRE (Java Runtime Environment). Understanding JVM means a much better understanding of Java as a programming language. JVM will assist you in solving complicated issues during the programming process.

As a Java developer, you should also be aware of the JVM restrictions on a stack and the standard errors that a lot of Java developers make.

 

6) Enhance your knowledge of working around design patterns

The importance of design patterns in software development is surely not hidden from you if you are an object-oriented software developer with some experience. Design pattern helps to depict the relations between the object and classes. If the naming of objects and classes gets done systematically, the recurring issue in these object-oriented systems gets addressed.

Be it a regular employee or even a freelancer, a deep understanding of design patterns is always going to be a big plus.

 

7) Get acquainted with JVM languages

While learning new languages is always great for you personally and professionally, developing a habit to learn new programming languages apart from Java will help you with the development in Java applications. For instance, Kotlin is a static programming language which operates on Java virtual machines and can be used further for compilation into JavaScript code or LLVM compiler too.

Taking up and learning new languages of programming helps you in making a comparison between the advantages and drawbacks that will, in turn, help you in creating better codes. Help in Android development through it is another plus.

 

Final Take Away…

If you want to become a pro Java developer and learn new coding and Java programming skills, exploring and showing due diligence to the above tips are bound to take you a long way into the game. Of course, you cannot learn everything all in a single go. Select a particular tip and then proceed towards enhancing it. Be mindful of learning Java 8 as a healthy working experience in Java 8 is essential for developing any application.
