Reproducible production environments are more important than other “nice to have” features: they enable successful deployments, performance testing, and fast incident response, by minimizing uncertainty and reducing downtime when most needed.

We will explore how TPA can help with replicate your Postgres production cluster, by enabling reproducibility as a solid engineering practice leading to improved performance confidence, safer deployments and overall system resilience. We will conclude with a practical example where we reproduce a production environment and then carry out performance testing at 1:1 scale while keeping cloud costs negligible.
