Operational modernization refers to updating your deployment operations to use container orchestration and with new DevOps and GitOps best practices.
Runtime modernization refers to moving applications from traditional WebSphere Application Server to Liberty or perhaps rewriting the front end to use Node.js. There are two parts to application modernization: runtime and operations. Application Modernization Assessment and Detailed Analysis It is a choice, not a requirement, and the WebSphere migration tools help you with that move as well. If you choose to update your application to a later Java EE level, you can do so to get the latest capability. With zero migration, you can create new images or install new Liberty binary files with no surprises. Zero MigrationĪfter the initial move to Liberty, the Liberty zero-migration architecture means that you can update the product runtime files and continue to use you existing unmodified applications and configuration with no unwanted or unexpected behavior changes. WebSphere Liberty is built from Open Liberty and contains more features for Java EE 6 web profile to ease some migration scenarios where we had different underlying implementations for Java EE technologies like JPA, JAX-RS, and CDI. If you want a fast, composable, production-ready, open source Java EE application server, look no further than Open Liberty. It supports the Java EE 7 and Java EE 8 full profile programming models. Open Liberty is the open source Liberty application server that is developed fully in the open at. So what is the difference between Open Liberty and WebSphere Liberty? It has high server throughput to handle your most important workloads. Liberty has one of the fastest startup times of any Java EE application servers, and it keeps getting better. When you adopt a container strategy, Liberty images are available for both Open Liberty and WebSphere Liberty on Docker Hub and Red Hat certified images.
Liberty is a container-ready Java™ EE application server that is perfect for containerized environments.
