Chapter 1. Introduction
1.1. Introduction
This document clarifies some important information related to features and support for Red Hat JBoss Data Grid, such as:
- The two JBoss Data Grid Usage Modes
- Supported JBoss Data Grid features
- JBoss Data Grid features that are limited to a technology preview.
1.2. About Usage Modes
Red Hat JBoss Data Grid offers two usage modes:
- Remote Client-Server mode
- Library mode
Remote Client-Server mode, which provides a managed, distributed and clusterable data grid server. Applications can remotely access the data grid server using Hot Rod , memcached or REST client APIs.
Library mode allows the user to build and deploy a custom runtime environment. The Library usage mode hosts a single data grid node in the applications process, with remote access to nodes hosted in other JVMs. Tested containers for JBoss Data Grid Library mode includes JBoss Enterprise Web Server and JBoss Enterprise Application Platform (see https://access.redhat.com/articles/2435931 for details about supported containers). Additionally, Library mode is supported outside the listed containers as a standalone application.
1.3. Features and Usage Modes
