Rapid advancements in cloud-based software delivery and virtualization have caused many developers to question the wisdom of a “Big Server” approach to deploying web applications. Spring Boot is a technology stack that builds on the popular Spring Framework to allow Spring-based applications as stand-alone jar files that host their web servers. This approach works nicely with deployment automation and rapid scaling.
Cloud-based, highly-distributed applications face additional challenges in supporting a dynamic environment – especially around configuration, service discovery, service resilience, and monitoring.
Spring Cloud embraces and extends the popular suite of open-source cloud tools published by Netflix (Eureka, Hystrix, Ribbon, etc.).

This course “Mastering Microservices with Spring Boot and Spring Cloud Training” is designed to guide you to the latest cloud programming concepts in Spring Boot Technology stack. This training requires previous coding experience/Knowledge. We recommend you to undergo our module 1 – “Java 11” and module 2 – “Programming Java SOAP and REST Web Services – JBoss / Eclipse Training” of our “Java Professional” training program to strengthen your core Java and advanced Java coding skills. In this course we will provide you with the knowledge to mastering latest advancements in cloud-based software delivery and virtualization called the “Big Server” approach to deploying web applications, Microservices with Spring Boot and Spring Cloud Training. You will learn to create Spring Boot projects, use databases and JPA in Spring Boot, create RESTful services with Spring Boot and deploy services that use Netflix Eureka, Hystrix and Ribbon to develop resilient and scalable services.
What is the Spring Framework?
Spring Framework is an open-source application container for Java that supplies many useful features, such as Inversion of Control, Dependency Injection, abstract data access, transaction management, and more. Spring was initially introduced back in 2002 by Rod Johnson as a 30K lines of code framework accompanying his book “Expert One-on-One J2EE Design and Development”. The framework was initially known as “interface21” but was later renamed and released as an open-source project under the name “Spring”.
What is the Spring Boot?
Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”. All in all, Spring Boot is a project built on the top of the Spring framework. It provides a simpler and faster way to set up, configure, and run web-based and straightforward applications. In the Spring core framework, you need to configure all the things for yourself. Hence, you can have a lot of configuration files, such as XML descriptors. That’s one out of the main problems that Spring Boot solves for you. It smartly chooses your dependencies, auto-configures all the features you will want to use, and you can start your application with one click. Furthermore, it also simplifies the deployment process of your application.
What is Inversion of Control (IoC)?
One of Spring’s core features it the usage of the concept Inversion of Control (IoC). IoC is about inverting the flow of control that the traditional programming model used to have in terms of objects at the higher-level handling the creation and management of lower-level things life cycle. In the IoC programming model, higher-level objects prefer one or more instances of these dependencies from the calling object or external framework. IOC is also termed Dependency Injection, wherein the dependencies are injected appropriately, and, objects bother themselves solely with the program execution and not with the object creation.
Simply said Inversion of Control (IoC) and Dependency Injection (DI) patterns are all about removing dependencies from your code.
Why should I become a Java Professional?
Here are a few reasons:
1) Java is one of the most widely used programming languages. There is no denying Java’s popularity using more than nine million developers on seven billion devices worldwide. Despite being released over 20 years ago, Java has been at the top of the TIOBE index, the measure of popularity within programming languages, for the last decade. Job prospects for people with Java skills are excellent with roles available across many different sectors.
2) There is more to Java developing than coding. When you become a Java developer, your work is varied due to the many different tasks that Java developers oversee. From designing interfaces to creating and testing dynamic applications, Java developers involved in every development process stage.
3) Java development is collaborative. An advantage of being involved throughout the development process is that Java developers collaborate with other professionals, such as Web Designers, Web Developers and Software Engineers. Collaboration develops communication and other transferable skills, which help advance your career as an IT professional.
4) Java is used in real-world applications. From healthcare to financial services, Java is used across many different business sectors and popular websites such as Facebook, Amazon and eBay. So, as Java developer, it is likely that your work will benefit not just the company you work for but also many ordinary people in real-life scenarios.
What role do Java developers play in IT development?
Java developers create complex web-based applications. Some examples include animated drop-down menus, images that change as a mouse moves over them, and sounds that play when clicked. Java is used extensively on e-commerce sites to collect data and validate user information. It is the job of Java developers to use this scripting language to modify the design and functionality of websites as requested by their clients. Java developers may write programs themselves or revise existing applications. They also identify opportunities to fine-tune and optimize applications of java developed projects. Java developers will often test programs to verify that they work correctly. This responsibility includes resolving technical issues through debugging, research and investigation. Java developers will also often mentor and provide technical guidance and instruction to lower-level IT staff, assisting with specific problems requiring a broad knowledge of subject matter processing.
Technology in the IT world is constantly changing, so knowledge becomes outdated in a few years. Therefore, a love of learning is essential for Java developers. Good researching skills are also crucial because there will always be new technologies to learn about. Java developers typically work on a team, so being a team player is extremely important. Good communication skills are also a must because Java developers must communicate effectively with their team and with clients.
