Maybe you've already heard about Eclipse MicroProfile, or maybe you don't know what benefits it offers you in your current project. Perhaps you don't see the relationship with Java EE/Jakarta EE - or how you can use it with Payara Server or Payara Micro.
In this blog, I'll give you a short overview of all of the above questions so that you can start using MicroProfile in your next project on the Payara Platform.
If you want to run and debug your application from within an IDE using Payara Micro, you need to take different steps and use a different configuration then when you run the application with Payara Server. With Payara Micro, you can start the runtime from a jar file with no previous installation step. In this blog, I'll show you the steps to use IntelliJ IDEA with Payara Micro and how you can perform a hot reload of the application.
Application updates are required as part of the normal maintenance process of your application lifecycle management. These updates should be as smooth as possible, and especially for a micro-services environment, performed with zero-downtime of your Payara Micro application. The Kubernetes Rolling Upgrades feature can help you with this.
Several Cloud Providers have the possibility to run your Payara Platform Docker Images on their infrastructure. In this blog, I will describe to you how you can run your application on Microsoft Azure using a Docker Container. All the steps required to perform this are described using the Azure Portal (web-based application) and the Azure Command line.
When using Docker images as the way to deploy your application, many organizations use Kubernetes to manage the containerized version of their application. This blog gives you a short overview of Kubernetes and how to run your Payara Micro application in a scaled fashion by either defining the scaling manually, or automatically by the Horizontal Pod scaler.
At the end of February 2019, we started with the phase-out of the Payara Platform 4. It does not mean the end of it, but a first waypoint in the lifecycle of it. You can see all phases of a Payara Platform on our Support Lifecycle page on the website (https://www.payara.fish/support/support-lifecycle/)
What is Docker?
Docker is a platform which makes it easier to create, deploy and run your applications using containers. A container bundles all the software needed to run it. By packaging the required dependencies, it makes it easy to run it on any machine, regardless of small configuration differences.
