The World is Moving Towards Microservices Architecture. Yes, it’s true but why? Microservices are becoming more popular day by day. To know Why the World is Moving Towards Microservices Architecture you must refer to this article. This will give you a complete idea of why big organizations like Google, Meta, Twitter, etc. are using Microservices nowadays.
Now the questions that arise are, What’s Microservices? Why it’s so much popular nowadays? Why Spring Boot For Microservices Development? What’s the best way to learn Microservices? How to start? Where to start? What topics one should cover? etc, etc. Do you need to learn all the concepts from a book or you should go with some online tutorials or you should learn Microservices by doing some projects on it? So in this article, we will discuss the complete roadmap for becoming a Java Spring Boot Microservices developer.
What is Microservice?
Microservice is nothing but an architecture pattern through which we can build bigger and more scalable applications. Microservice provides to handle a large application and break it into efficiently small components with some selected responsibilities. Please refer to this article for a detailed explanation: What is Microservice Architecture and Why to Use Them?
Microservices could be written in various programming languages and frameworks, but the point is that why Spring Boot is one of the best frameworks for Microservices Development.
Why Spring Boot For Microservices Development?
Spring Boot is built on top of the traditional Spring Framework. And it provides all the features of Spring. It is a microservice-based framework that makes a production-ready application in a very shorter time. Below are the 7 major points to prove Spring Boot is Best for Microservices Development.
- Embedded Server
- Support Load Balancer
- Auto Configuration
- Minimal Code using Annotations
- Loose Coupling
- Dependency Management
- Open Source
We have covered a detailed explanation in this article: 7 Major Reasons to Choose Spring Boot For Microservices Development
Why Microservices? (Decide the Goal First)
Before jumping into the complete Roadmap of Java Spring Boot Microservices, you should have a clear goal in your mind that is why you want to learn Microservices. Is it for your college academic projects? Or Is it for your long-term career? So first make a clear goal. Why do you want to learn Microservices?
Roadmap For Spring Boot Microservices
Start with the Overview of Microservices. Read some Microservices-related blogs and also research some Microservices-related things. For example, read blogs on Introduction to Microservices, Why Microservices? If there is already Monolithic Architecture then why there is a need for Microservices Architecture? etc., etc., and make a complete mind makeup to start your journey on Java Spring Boot Microservices. Do it regularly and also start learning one by one new concept on Microservices. It will be better to join some workshops on Java, Spring Boot, and Microservices before you start your journey.
Before learning Microservices one should learn Java first then Spring Framework then Spring Boot then Microservices. But what to learn from these 4 things? Let’s discuss it in detail.
1. Learn Java Programming
One may consider this step as a prerequisite. Learn Java programming language in depth before you start learning Spring Boot. Along with Java, you must learn the following things before jumping to Spring Framework. You needn’t go in-depth but you should know the basic.
2. Learn Spring Framework
To master Spring Boot you need to learn the Spring framework first. So we will suggest, you must know the basics of the Spring framework at least.
- Spring Core
- Spring JDBC
- Spring REST
- Spring Data JPA
- Spring AOP
- Spring Security
- Spring JMS (Kafka, RabbitMQ)
After learning this much of thing you are ready to jump to Spring Boot.
3. Start with Spring Boot
Once you are finished with the spring framework and implementation of spring security then you need to switch to spring boot. At that time you will get the best moment of Spring Boot because whatever the configuration you are doing for the spring application will be automated in the spring boot. So you need to learn the following things in spring boot
- Importance of Spring Boot
- Auto Configuration and Adding Configuration
- Properties/YAML
- Integration with other libraries/frameworks
- REST API
We have prepared a complete Spring Boot roadmap already. Please refer to this article: Best Way to Master Spring Boot – A Complete Roadmap
Once you are complete with the above things now you can jump to Microservices.
4. What to Learn in Microservices
So once you’re good with the Spring Boot the next thing that you should switch to microservices. We know this is the trending tech right now and you as a developer should upgrade your skills and should understand the microservices architecture. You should understand how to write applications inside a microservices environment. A lot of people jump directly to the microservices because their company is forcing them to learn microservices and they just skipped the above thing and that is going to be a really challenging scenario. Think, you are developing microservices and you are using Java as a technology and you are using spring boot as a framework then you should at least understand what different modules of Spring are available like core spring, spring AOP, spring security, etc and Also you have to learn spring boot as we said that’s really important and then this microservices is just an architecture. This is nothing else you’ll not be learning something really fancy over here. You’ll be learning some design patterns.
We have prepared a complete article on Why Use Spring Cloud for Microservices Development. Please refer.
- Design Patterns
- DevOps
- Tools
And there are many tools available for Microservices development you can explore all of them. It will be very fun to work with Microservices Architecture.
Conclusion
Remember, mastering Java Spring Boot Microservices is a journey that requires practice and dedication. By following this roadmap, you’ll build a strong foundation and gradually elevate your skills. So, whether you’re crafting apps that make life easier, websites that dazzle, or systems that run the show behind the scenes, you’re now equipped with the know-how to weave the magic of microservices using Java Spring Boot. So, gear up, stay curious, and get ready to conquer the world of microservices with Java Spring Boot.
FAQs on Java SpringBoot Microservices Roadmap
1. What is Spring Boot, and why is it important for microservices?
Spring Boot is a framework that simplifies the development of Java applications, especially microservices. It provides tools and conventions to quickly create standalone, production-grade applications with minimal configuration. Its ease of use and powerful features make it a popular choice for building microservices.
2. Can I build microservices without Spring Boot?
Yes, you can, but Spring Boot significantly simplifies the process. It handles various concerns like dependency management, configuration, and deployment, allowing you to focus on building the actual functionality of your microservices.
3. How do microservices communicate with each other?
Microservices communicate through APIs (Application Programming Interfaces). They can use various protocols like HTTP, message queues, or even events. Spring Boot offers tools to facilitate inter-microservice communication.
