IBM® WebSphere® Application Server Liberty Core is a lightweight and dynamic application server based on the developer-friendly Liberty profile. Designed for web applications that do not require a full Java EE stack, but this WebSphere solution is certified to the Java EE 7 Full and Web Profile specifications. The capabilities available in the Liberty Core edition are a subset of the Liberty profile features provided in other editions of WebSphere Application Server. WebSphere Application Server Liberty Core enables less complex, rapid development and deployment of web and mobile applications using fewer resources for responding to evolving enterprise and market needs more quickly.
WebSphere Application Server Liberty Core helps you: increase developer productivity with open standards and broad programming models, including lightweight options for web deployments; deliver custom applications via extensions to the Liberty profile; and package and deploy applications and services with upmost efficiency.
WebSphere Liberty has a no-charge and no-support option for web-centric application usage in test and production environments, which is limited to a combined 2 GB of memory across all instances of application servers for the licensee. Production usage beyond a combined 2 GB of heap size requires purchase of license entitlements.
