# Blue-green deployments in Octopus using Environments

To implement [blue/green deployments](https://octopus.com/devops/software-deployments/blue-green-deployment/) in Octopus using [Environments](/docs/infrastructure/environments), create two environments - one for blue, and one for green:

When deploying, you can then choose which environment to deploy to - either blue or green. The dashboard will show which release is in each environment.

Configuring your [lifecycle](/docs/releases/lifecycles) will need to be done accordingly. You would typically have both your blue and green environments in a shared "Production/Staging" phase.
