In today's IT landscape, if an application is being built from scratch, it is easy to embark on a journey to explore a host of tempting shining technologies. There are countless frameworks that are used to build modern applications leading you to believe that if your infrastructure does not match them, your company is doomed to a legacy limbo. Because of this misconception, modernizing your application is a subject that often is surrounded by myths and not discussed in a broader form.
Applications are just one of many parts of a complex system. They coexist with networks, hardware, other software, software engines, and data repositories used to process and store data and information. Switching applications for a more "modern" one is a complex task because it is not just a simple swap. It is necessary to reconsider your infrastructure, user training, and how your business will be affected by the change. A daunting task no doubt.
The State of Developer Ecosystem 2020 report shows Java is still the primary programming language among developers. Used on websites, web back-end, mobile development, and many other areas, Java applications continue to represent a big portion of the enterprise applications market and can rely on an abundance of experienced professionals and a solid community. Modern Java frameworks enable you to build microservices or stand-alone applications. Java provides a one-stop-shop for any challenge.
Most Java applications are insulated from the bottom part of the server stack (hardware and OS). This means that the top part of the stack (JVM, application server, and custom applications) can be moved to a different platform (i.e. RISC/Unix to x86_64/Linux or x86_64/Windows). That is Java portability: build once and run anywhere.
Oracle continues to bring value to Java to address the evolving needs of modern application developers. Oracle includes the free use of GraalVM Enterprise with the Java SE Subscription or when running on OCI. GraalVM Enterprise helps create executables that are ideal for microservice deployment because they startup almost instantly with reduced memory and compute footprint.
Moving to the application servers, the applications, and their components can be decoupled into different contexts. Contexts can be grouped or spread on multiple individual servers, clusters, or containers. At this point, nothing has changed but your application is ready to take advantage of the new infrastructure and its perks, or if necessary, take a leap forward and re-design using microservices architecture for example.
In your journey to modernize your application, Oracle Cloud becomes an excellent option as it allows, but is not limited to:
One unique benefit to migrating workloads to OCI is access to GraalVM Enterprise's patented optimizations that accelerate Java application performance or compile native executables with near-instantaneous startup ideal for microservice deployment.
Modernizing your infrastructure doesn't require a complete overhaul. It can be gradual, tailored, and smooth. Take a peek at our growing collection of reference architectures to help you speed up your journey. Here are a few reference architectures that demonstrate how your Java application can be deployed on OCI:
