About this page

Terraform is a single-topic module. This module covers Terraform core — HCL, resources, state, modules, workspaces, variables, backend, the plan/apply lifecycle — organized as an elevation arc within the one topic from 'what is Terraform and IaC' through to production patterns (state locking, module design, drift).

CI/CD Pipelines Interview Questions

CI/CD interviews test whether you understand the pipeline as a system, not a script. This module is an elevation arc: it opens with CI/CD fundamentals (the build-test-deploy loop, why it exists), then GitHub Actions (the most-asked modern CI tool), then deployment strategies (blue-green, canary, rolling), then rollback strategies (the thing that saves you at 2am). It closes with comparisons and scenario-based pipeline-design questions.
