Unexpected production errors often come from a familiar place: shared environments that fail to accurately validate real-world conditions.
Ephemeral Environments (EEs) offer a different approach. Instead of relying on fragile, long-lived shared environments, teams can validate each change in an isolated, production-like environment that includes code, infrastructure, and configuration.
In this talk, we’ll explore how EEs reduce unexpected issues in production by improving quality validation, eliminating cross-team interference, enabling safer automated testing, and accelerating deployments.
But prevention is only part of the story.
We’ll also touch on how the same environments can be used after an incident to reproduce failures, reconstruct system state, and support deeper root cause analysis and post-mortems.
This session focuses on how SRE teams can use an incremental and adaptable ephemeral strategy to connect prevention and incident response into a continuous reliability loop.
