Overview
What is IBM WebSphere Liberty?
IBM® WebSphere® Liberty is a Java EE application server with a low-overhead Java runtime environment for cloud-native apps and microservices. WebSphere Liberty was created to be highly composable, start fast, use less memory and scale easily. Using the open-sourced IBM Open Liberty (link resides outside IBM) code base provides low-cost experimentation, customization and seamless migration from open source to production.
