Java Microservices with Spring in 2 Weeks

Microservices have become a de facto standard architecture pattern of today’s software. Due to their nature, microservices give developers a lot of freedom in using the right tool and language to solve a given business problem. The Spring Framework—specifically Spring Boot and Spring Cloud— have revolutionized modern Java microservice development. With these frameworks you can set up your applications in no time, reusing abstractions dedicated to working in the cloud regardless of your chosen platform.In this 2 week course, we will look at how Spring Boot and Spring Cloud work with Kubernetes to create and deploy your microservices. We will also learn how you can leverage those frameworks to do HTTP and messaging based communication. This course is targeted for everyone writing Spring based microservices. You’ll learn how to make your microservices communicate in a resilient manner and how to interact with your deployed to production application.

Week 1: Introduction to Microservices with Spring Boot & Spring Cloud

We can see that more and more companies are creating microservices and are deploying them into Kubernetes. Since Spring Boot is the de facto standard for such setup it’s good to review the changes in its latest versions that offer best out-of-the-box support for Kubernetes.

In Week 1 of this course, we will look into some of the most fundamental features of Spring Cloud that abstract the underlying platform where the application got deployed to. We will also answer the question when to use and when to not use Spring Cloud Kubernetes.

Week 2: Microservice Communication with Spring Boot & Spring Cloud

Applications deployed to a cloud never remain in isolation. They need to communicate with each other - the most common means are HTTP and messaging. There are quite a few questions we should pose and answer before we start coding. Since we don’t have knowledge of the IP and port of applications deployed to a cloud, how can we actually make an HTTP call? How can we easily set up a messaging communication? What if the communication is faulty? How can we ensure that our applications do not propagate failure? What if we want to put an API gateway on the edge of our system - what’s the easiest way to write one?

In Week 2 of this course, we will tackle all of those problems by using Spring Boot and Spring Cloud. We will see how to leverage service discovery so as not to hardcode IP and ports of other applications. We will use circuit breakers to ensure that our system is stable when one of its components is misbehaving. We will build an API gateway using Spring Cloud Gateway. What about messaging? We will see what Spring Cloud Stream is and how we can decouple messaging functions from the broker to which the messages will be sent.

NOTE: With today’s registration, you’ll be signed up for all 3 sessions. Although you can attend any of the sessions individually, we recommend participating in all 2 weeks.
