Cloud and Infrastructure-as-Code Interview Deep Dive: Reasoning Through Real Scenarios
The cloud and IaC scenarios that test real operational judgment -- a dangerous Terraform plan, handling secrets in a pipeline safely, designing around a region outage, and investigating a sudden cost spike.
Learning objectives
- Explain what causes Terraform to plan a destroy-and-recreate and how to verify whether that's actually safe
- Compare the common patterns for handling secrets in a CI/CD pipeline and their respective risk profiles
- Reason about the real design tradeoffs involved in surviving a region-level outage
- Build a systematic approach to investigating an unexpected cloud cost spike
