Summary
In Episode 68 of The Site Reliability Podcast, Lucas and Luna explore how SRE teams use infrastructure as code (IaC) to prevent configuration drift — the silent killer of production reliability. They break down a real incident at a mid-sized fintech company where a manual SSH change caused a partial outage, and how the team rebuilt their entire environment with Terraform and automated compliance checks. Lucas explains the technical difference between declarative and imperative IaC, and why treating infrastructure like application code — with pull requests, code reviews, and unit tests — reduces human error by over 80 percent. Luna shares a surprising stat from a 2025 Cloud Posse survey: 63 percent of SRE teams still rely on partial manual config changes. They discuss practical steps to start small, like using Terraform for a single service, and the importance of integrating IaC with incident response playbooks. If you're an SRE or platform engineer struggling with snowflake servers, this episode offers concrete strategies to enforce consistency and reduce toil.
