Features and benefits of Liberty Core
Liberty Core offers you the following benefits:
A lightweight edition, which contains the subset of Liberty that corresponds to the Jakarta EE Web Profile specification.
Excellent development and production runtime environments for web applications.
A smaller footprint for faster download and startup, giving more development time and faster time to deployment.
Ease of packaging applications for deployment, including configuration.
The ability to run applications that are written for Liberty Core on WebSphere Application Server traditional and Liberty.
The ability to extend the Liberty capabilities by adding custom features that use a product extension System Programming Interface (SPI).
The Liberty Core edition focuses on Web Profile capabilities such as servlet, JSP, JSF, and EJB-Lite. Liberty Core has a different programming model from other WebSphere Application Server editions. For example, Liberty Core does not include Java Message Service (JMS) or Web Services, making Liberty Core edition lightweight and focused on the capabilities that are needed to deliver Web Profile applications.
Differences between Liberty Core, WebSphere Liberty, and Open Liberty
Liberty Core provides a subset of the capabilities that are provided in WebSphere Application Server Liberty. However, the following capabilities are available and supported in Liberty Core, but not in Open Liberty:
Ability to use Java EE 6 technologies
Product installation with Installation Manager
WebSphere Liberty on IBM i operating systems
Most Liberty features and capabilities are now documented on the Open Liberty website. However, capabilities that are specific to WebSphere Liberty and some older features and capabilities are documented only in the WebSphere Liberty documentation. Features that are valid for both runtimes are documented in both WebSphere Liberty and Open Liberty, although the extent of what is documented about a feature might vary between the two websites.
