The Payara Platform 2021 Survey is underway and we’re inviting everyone to answer a few questions about your use of the Payara Platform and ecosystem components.
We want to know what you like, what you want to see improved, and we’re giving you the opportunity to vote on new features you’d like to see added to the Payara Platform.
Your survey answers help drive future development efforts for the Payara Platform.
This article covers some internals of image layering created by container image builder Jib and explore what distroless images are and their benefits.
In short, Jib is an excellent tool for Java developers who are interested in containerizing Java applications, but not so interested in creating and maintaining Dockerfile or installing Docker. A Java developer can add a plugin to Maven or Gradle, and that’s it. You don’t have to learn new technology just to containerize your Java application.
Now, let’s talk about some internals.
The MicroProfile OpenTracing specification defines behaviours and an API for accessing an OpenTracing compliant Tracer object within your JAX-RS application. The behaviours specify how incoming and outgoing requests will have OpenTracing Spans automatically created. The API defines how to explicitly disable or enable tracing for given endpoints.
Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It is used for monitoring and troubleshooting microservices-based distributed systems.
Let’s use a 20 year old JAR, once created for a Java Applet to be run in the Java 1.1 Browser Plugin… and run it on JDK 11!
It now runs outside of any Web Browser and without modifying its decades-old JAR. The Applet was once created and offered to browse through all raw color images uploaded by the Mars Pathfinder Lander which settled down on the planet on July 4th, 1997.
Kubernetes is much more than a runtime platform for Docker containers.
Through its API, you can not only create custom clients, but you can also extend Kubernetes. Those custom Controllers are called Operators and work with application-specific custom resource definitions. You can not only write those Kubernetes operators in Go, but you can do this also in Java.
In this talk, delivered by Payara’s Rudy De Busscher at JCON 2020, you will be guided through setting up and your first explorations of the Kubernetes API within a plain Java program.
Developing applications with Kubernetes is not such an easy task and that’s where Skaffold comes into play.
It eases the development and deployment of your applications running on Kubernetes.
It manages the entire workflow and you get instant feedback while developing and deploying your application locally or on a remote Kubernetes cluster.
All companies are software companies, and businesses will always experience the challenge of keeping integrations between users and applications scalable, productive, fast, and of high quality.
To combat this, cloud, microservices, and other modern solutions come up more and more in architectural decisions.
Here is the question: Is Java prepared to deal with these diverse concepts in a corporate environment?
In this post, we will learn about how to create Docker or OCI compliant images, without installing any Docker client and without using a Dockerfile, for a Spring Boot application.
Other benefits of using Jib for your Java applications include that it’s super easy to integrate with Java applications, producing faster builds, reproducible builds, community support, etc.
To celebrate the world of Java and predict our highlights for 2021, several key Foojay participants will share their thoughts and hopes during the coming days on Foojay, starting with Frank Delporte, Foojay Community Manager for the Raspberry Pi, and now continuing with Jadon Ortlepp, Foojay Community Manager for Microservices, who here provides the predictions of his Payara colleagues on Jakarta EE in 2021.
“Jakarta EE will start driving improvements in APIs and Project Loom will drive new releases of many frameworks.”
Docker is the most widely used way to containerize your application. With Docker Hub, it is easy to create and pull pre-created images. This is very convenient as you can use these images from Docker Hub to quickly build an image for your Java application.
However, the naive way of creating custom Docker images for your Java applications comes with many security concerns. So, how do we make security an essential part of Docker images for Java?
The two main advantages of Java AOT natively compiled microservice frameworks are rapid boot times and reduced JVM memory usage. While technically impressive, the reality is that neither of these advantages delivers a significant economic or technical advantage when deploying to public clouds.
Many Jakarta EE runtimes (like Payara Micro) are small and fast. They can run Jakarta EE applications as either monoliths or microservices in the cloud now, with no need to adapt or rewrite your applications to proprietary frameworks.
