Hello guys, if you want to learn Microservice architecture and look for free Microservice resources like free online courses, you have come to the right place.
Earlier, I have shared the best Microservice courses to build Microservice using Java and the Spring framework, and today, I will share some free courses to learn Microservice in Java using Spring Boot and the Spring Cloud framework.
If you don't know, Microservices is a modern architecture that goes along nicely with cloud computing and makes deployment, scaling, and even development easier.
It provides a new way to deploy your Java application where a monolithic Java application is broken down into multiple, small, independent Java applications which can be developed, deployed, and tested independently.
There are several benefits of following Microservice architecture like, multiple developers can work on multiple processes simultaneously. The build and release process becomes easier as you are only deploying things that you are changing.
Another great thing about Microservice is that it goes hand-in-hand with the cloud. They are easier to scale and often deployed using containers like Docker, which makes the deployment easier which can also be automated using Kubernetes for further scaling.
With an increased push to move towards Cloud-based Architecture, Microservice is getting a lot of traction and becoming popular every passing day. It has now become an essential skill for Java developers.
When developing Microservice-based applications in Java, the Spring framework offers the best solution to create, maintain, and deploy enterprise-scale Microservices. Microservices allow extensive systems to be built up, from several small collaborating components.
If you look closely, it follows the Spring model of component-based development. Microservice is built using a small process that collaborates to do what you indent do. Spring also does the same where the application is made of small, collaborating components, Java classes, or Spring beans. This loosely coupled design offers many benefits which powered modern software development.
By the way, If you are keen on Microservice development using Spring Boot and Spring Cloud, then I highly recommend Master Microservices with Spring Boot and Spring Cloud course on Udemy. It's not free but quite affordable, and you can buy it for just $10 on Udemy sales.
