Application Environments

An environment is a user-defined collection of resources that hosts an application. An environment is the application's mechanism for bringing together components with the agent that actually deploys them. Environments are typically modeled on some stage of the software project life cycle, such as development, QA, or production. A resource is a deployment target, such as a database or J2EE container. Resources are usually found on the same host where the agent that manages them is located. A host can be a physical machine, virtual machine, or be cloud-based.

Environments can have different topologies—for example: an environment can consist of a single machine; be spread over several machines; or spread over clusters of machines. Environments are application scoped. Although multi-tenant machines can be the target of multiple applications, experience has shown that most IT organizations use application-specific environments. Additionally, approvals are generally scoped to environments.

Serena Release Automation maintains an inventory of every artifact deployed to each environment and tracks the differences between them.
