Java Heap Sizing in a Container: Quickly and Easily

In the previous blog, We have seen that Java has made improvements to identify the memory based on a running environment i.e. either a physical machine or a Container (docker). The initial problem with java was that It wasn't able to figure out that it was running in a container and It used to capture the memory for whole hardware where the container was running. (Please see - ttps://blogs.oracle.com/java/java-on-container-like-a-pro) Now a Java Program running in a container...

JVM in containers Modern day software systems are moving towards containers. But there are a few important factors to understand before we move our Java/JVM based applications to containers. These factors raise questions about Java's suitability for containers. Imagine an environment in which 10 instances of an application have been deployed into a container. Suddenly the application starts throttling and falling short of the normal performance. What has happened? In order to...

The second annual Oracle Code One conference will soon be here.  Again, it will showcase a wide and deep variety of developer technology initiatives Oracle is investing and participating in…from machine learning to artificial intelligence, autonomous database to microservices, and of course the Cloud. Yet, the primary conference focus continues to shine a bright spotlight on Java technology.  That’s because Java remains an important area for Oracle in terms of stewardship,...

By Java Magazine Editor Andrew Binstock In our previous issue, we explored the use of lightweight frameworks— Javalin, Micronaut, and Helidon—to create microservices, which typically are deployed in the cloud. In that issue’s article on Helidon, we also showed how to package a service into a Docker container for deployment. In this issue, we continue the theme by examining how to build apps with containers in mind and how to deploy containers. For straight Java apps, the...

By Java Magazine Editor Andrew Binstock  Running Fast and Light Without All the Baggage The emergence of microservices as the new architecture for applications has led to a fundamental change in the way we use frameworks. Previously, frameworks offered an omnibus scaffolding that handled most needs of monolithic applications. But as microservices have gained traction, applications now consist of orchestrated containers, each performing a single service. As such, those...

There is a lot happening in Java, and in this issue we do our best to make the state of Java as clear as possible. We begin with a survey (page 15) of Java developers. The survey covers JDK, tools in use, processes, and finally a profile of Java developers. We follow that up with a look at Java 11 (page 39), which was released in September: what’s in this release that you need to know about—such as changes to lambda syntax, a new HTTP client, and the updated WebSocket...

The Java Platform Module System (JPMS) main goal is to make it easier to construct and maintain Java libraries and large applications. You will also experience improved application performance by scaling down the Java SE platform and JDK. In a series of five tutorials, Deepak Vohra explains how to use the module system in your applications. He walks you through setting up your environment, creating classes within modules, configuring VM Args for your module path and running...
