This complexity arises because a cloud native solution operates in a world where scale, demand, and availability are significant factors. Software design and cloud solutionsįinally, it’s important to understand that a modern cloud native application is more complex than traditional applications. Cloud native Java runtimes like Eclipse OpenJ9 offer substantial benefits in runtime costs while maintaining maximum throughput. Two decades worth of improvements in performance and steady evolution have made Java an excellent general-purpose programming language. The Java platform and JVM are the perfect mix of performance and innovation. Couple this need with cloud’s rapid evolution, and you are looking for a runtime with a pedigree of performance and innovation. In general, developers need runtimes that are fast to start, consume less memory, and still perform at a high level. That means that cloud native applications need to be frugal and yet still performant. In a cloud environment, the amount of compute resource is usually lower and, of course, you pay for what you use. Next, consider that a cloud environment has a significantly different profile from a traditional one that runs on a local server.

Cloud native continues to evolve, so it’s important to keep abreast of its direction and utilize the best capabilities as they’re developed in the Java community. They are exploring all the aspects of what it means to be cloud native-whether it is serverless, reactive, or even event driven. The community that created Enterprise Java and has made it the de facto business platform is also the community that is leading the evolution of cloud native thinking. The Java community is the leader in the business applications space, and Java developers have the deepest knowledge and experience for enterprise applications. The first consideration is simply the pace of innovation, and where it is taking place. The depth of the Java community’s business knowledge, the Java Virtual Machine’s (JVM) unrivaled performance with flexibility, and developer friendliness are among the reasons. In this article, we discuss the reasons why Java is an excellent programming language and platform for cloud native applications. In reality, though, there are several factors that should influence your choice of a programming language. In principle, any programming language can be used to create microservices.

This post is adapted from Developing Open Cloud Native Microservices: Your Java Code in Action, a new report from IBM on what you need to know when building new cloud-based applications.
