Deployment configurations for eXtreme Scale
WebSphere eXtreme Scale can be deployed into two types of environments: local or distributed. The configuration that is necessary depends on the type of deployment environment.
Local environments
When you deploy in a local environment, eXtreme Scale runs within a single Java™ virtual machine, and is not replicated. A local environment requires an ObjectGrid XML file or ObjectGrid APIs.
Distributed environments
When you deploy in a distributed environment, eXtreme Scale runs across a set of Java virtual machines. With this configuration, you can use data replication and partitioning. A distributed environment can be further classified as a dynamic deployment topology in which you can add servers as needed. As with a local environment, an ObjectGrid XML file, or an equivalent programmatic configuration, is needed in a distributed environment. Additionally, provide a deployment policy XML file with configuration details for the eXtreme Scale in-memory data grid.
