Java Microservices with JHipster, Istio, and Kubernetes

Istio service mesh is one of the coolest kids on the block. It moves the responsibility of service discovery, load balancing, circuit breaking, monitoring, and so on from the application to the platform (Kubernetes), enabling developers to focus on the business code. But setting it up can be a daunting task for beginners and pros alike. This is where JHipster steps in and makes everything a cakewalk. JHipster is a widely used OSS application development platform for creating web applications and microservices in minutes. In this session, you’ll learn how to create a production-grade Java microservice architecture with Spring Boot, Istio, Docker, Kubernetes, and JHipster and deploy it to the cloud in under 30 minutes. As a bonus, you’ll learn how Istio works in the process.
