Environments are how you organize your deployment targets (whether on-premises servers or cloud services) into groups that represent the different stages of your deployment pipeline, for instance, development, test, and production.
Organizing your deployment targets into environments lets you define your deployment processes (no matter how many deployment targets or steps are involved) and have Octopus deploy the right versions of your software to the right environments at the right time. The order your projects progress through your environments is controlled by the lifecycle.
You can manage your environments by navigating to Infrastructure ➜ Environments in the Octopus Web Portal:
