If your team is still sharing a handful of long‑lived “dev”, “staging”, and “QA” environments, you’re leaving a lot of speed and reliability on the table. Modern teams are quietly switching to ephemeral environments—short‑lived, on‑demand environments spun up per feature, per branch, or even per pull request. They disappear when you’re done, but the impact on quality, collaboration, and delivery speed is very real.
