It is competing with Python and JS as the most popular programming language for the Enterprise year after year. Thanks to Java’s long history, the industry has plenty of Java-based systems, services, and applications. This is due to the Java Community Process (JCP) that helps optimize Java standards for any progressive needs and its six-month release cadence. While many other technologies have emerged and disappeared during that time, this language is still moving forward. In 2020, Java celebrated its 25th anniversary. Dynamic horizontal and vertical scalability.
Such piece of software should be written with technology native to cloud computing and exhibit at least some of the following features: So, in its purest sense, cloud-native Java development is an approach to building Java and JVM-based applications geared initially toward cloud frameworks instead of being adapted ex-post. Developers and operations collaborate so that their customers get the highest-quality product.
When an organization applies DevOps, every procedure is set toward readying code for deployment at any time: I t works within a production-first mindset and a live-site culture. It is defined as the union of people, processes, and end-results to ensure automated software delivery. These practices are based on the Agile methodology and depend on automation to push updates into production in small chunks rather than in bulk.Īn acronym from “software development” and “IT operations,” DevOps is an overarching concept. Container size depends on various parameters but always on the base OS image and runtime.Ĭontinuous integration (CI) and continuous delivery (CD) make your application’s release cycle fast, frequent, and reliable. A container image is layered and includes everything an application needs to run in the cloud: its code with dependencies, framework, OS packages and the operating system itself, runtime environment, system tools, and libraries. They are often opposed to virtual machines since they leverage a separate, more lightweight type of virtualization based on OS instances. The wide adoption of microservices makes Docker containers indispensable. An alternative to monoliths, microservices are lightweight and great for building clear interfaces. Microservice architecture represents a set of loosely coupled elements that run independently, each executing its own functionality and communicating with the others via APIs. It’s a small, individual application component with a high degree of autonomy in terms of deployment and scalability.
As VMware puts it, the cloud-native methodology rests upon four pillars: microservices, containers, CI/CD, and DevOps.Ī microservice bears several characteristics. To understand the concept, first we need to look into its constituent parts.
To read the entire Refcard, please download the PDF from the link above. This is a preview of the Introduction to Cloud-Native Java Refcard. You’ll get everything that is required to make your project cloud-native: tools, an assessment of advantages and limitations, a detailed user guide, and a walkthrough example to get you started right away. In this Refcard, we go through the basic explanations of cloud-native development on Java and see the scope of capabilities brought by multiple utilities. And those that use Java, one of the most popular programming languages, are major beneficiaries of this approach thanks to containers, JVM optimizations, multi-purpose frameworks, and native image technology. Writing, deploying, and managing applications outside of local machines opens countless opportunities for businesses around the world. Ever since the first virtualized services emerged in the 90s, it was only a matter of time before the software development process in its entirety moved to the cloud. Cloud-native solutions are not a novelty thing.
