Running Java Microservices in Kubernetes

Microservices tied together with RabbitMQ and Couchbase

In my previous article Java Configuration for Docker, I took a set of microservices, made Docker images from them, and tested it all out using Docker Compose. Now I will take it one step closer to production-ready by migrating all of that to Kubernetes. Kubernetes will give me the orchestration aspects to scale my system up and down as needed, plus the possibility of industrial-strength monitoring.

But first I should make some decisions. The services are reliant on RabbitMQ and Couchbase. Should these components run inside of Kubernetes or outside? There are pros and cons of each that I could write a whole article on, but I’m going to make the decision to run them inside Kubernetes, making this article more about running things in Kubernetes, than the intricacy and infinite possibilities of running them stand-alone. If I was implementing this in a production environment, I would strongly consider running them stand-alone.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.

Microservices in Java | Making Java easy to learn

This tutorial talks about “Microservices In JAVA” in detail.

It’s not just the Microservices developed using the Java language. There are still many things behind the scene that need our attention. When it comes to developing Microservices, an essential question is which language to choose. JVM is a notable platform in Java that offers developers  a great opportunity to use a different language abroad. The strength of the Java-based Microservice architecture is that it makes easier for developers to analyze with other languages or frameworks also without having a very heavy risk.

Moreover, particularly frameworks such as Spring Boot are well recognized and provide great help in building Microservices. Spring Boot provides you embedded servers such as Tomcat, Jetty, Undertow. It helps you to build .jar files very easily with an embedded web server and you can run it anywhere straight away. You don’t need to set up any server separately to run the application. No matter, if you are developing application for configuration, security, REST API, Batch Processing, mobile or even Big Data, there is a Spring Boot Project for you to make development easier & faster. Get More detail on it.
