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 own 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).

At Web Age, we offer the best spring boot course! This Mastering Microservices with Spring Cloud and Spring Boot training course introduces Spring Boot, Spring Cloud and the Netflix OSS suite as a way of deploying highly resilient and scalable RESTful services and web applications.

What is 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”. You can read the full story at Spring’s blog.

What is 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 both simple and web-based 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 objects life cycle. In the IoC programming model, higher-level objects rather receive one or more instances of these dependencies from the calling object or external framework. This is why 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.

Can I take Spring Boot Training online?

Yes! Our Spring Boot courses are available as “onsite live training” or “remote live training”. Onsite live Spring Boot Training and Spring Framework training can be carried out locally on customer premises or in Web Age corporate training centers. Our live Spring Boot online training is carried out by way of an interactive, remote desktop.
