A partition provides a runtime and administrative subdivision or slice of an application server domain. An application can be deployed to a particular partition, or otherwise associated with a particular domain partition name. The domain partition name can be used by the data grid to enable a separation of data between different partitions or between tenants associated with those partitions. In some embodiments, one or more data grid services, for example caches and clustered services, can be shared across multiple partitions. Alternatively, the data grid can provide read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other. ## Claims ### Claim 1 A system for supporting partitions in an application server environment, comprising: one or more computers, including an application server environment that provides deployment and execution of software applications, wherein the application server environment includes: a domain configuration that is used at runtime to define a domain for execution of software applications, and a plurality of partitions, wherein each partition, of the plurality of partitions, is associated with a partition identifier and a partition configuration, and provides an administrative and runtime subdivision of the domain, and wherein each partition of the plurality of partitions includes one or more resource groups, and wherein each partition is associated with a virtual target information and is accessible via a partition-specific virtual target associated with the partition at which that partition accepts incoming traffic to that partition and its resources;
