Short-lived copies of your stack that exist only as long as they are needed.
Quick Definition
Ephemeral environments are temporary, on-demand environments spun up for a specific purpose, such as testing a pull request, and torn down when no longer needed. They improve development workflows while controlling cost by avoiding always-on, idle infrastructure.
An ephemeral environment is a complete, disposable copy of an application stack created on demand, often for a single pull request or test run, and destroyed automatically when its job is done. Instead of maintaining a handful of permanent staging environments that teams queue for, every change gets its own clean world.
They improve quality and cost at the same time. Quality, because each change is tested in isolation against a fresh environment. Cost, because the environment lives for hours instead of months. The discipline that makes this work is automation: environments must be defined as infrastructure as code so they can be created and torn down without human effort.
Example. A developer opens a pull request and the pipeline spins up a full preview environment with its own URL. Reviewers click through the real feature. When the request merges, the environment deletes itself within minutes.
The cost failure mode is teardown that silently breaks, leaving zombie environments running for weeks. Tag everything ephemeral and alert on age. The CI/CD best practices guide covers the pipeline side.
Usually cheaper than permanent staging. Many short-lived environments cost less than a few long-lived ones that run around the clock
Infrastructure as code, automated pipelines, seeded test data, and a reliable teardown step with an expiry safety net.
Often they replace most of it. Some teams keep one stable pre-production environment for final integration checks
