Introducing Ephemeral Environments

Ephemeral environments in Octopus offer a solution to the common development issue of code working only on individual machines by allowing self-hosted and cloud customers to test changes in isolated, temporary environments before integrating them into the main branch. This approach provides faster feedback by testing changes in isolation, reduces infrastructure costs by automatically removing unused resources, and supports scalability by facilitating pull request reviews and feature testing. The integration with existing Octopus projects and infrastructure automation ensures seamless implementation. Setting up involves configuring a parent environment to manage variables and permissions, defining a naming template to avoid conflicts, and using runbooks to automate the provisioning and deprovisioning of resources. Multi-project support allows sharing of ephemeral environments, ensuring consistent testing across services, with flexible deprovisioning options to manage resource usage efficiently.
