Helm chart overview: Chart.yaml, values.yaml and templates produce Kubernetes manifests; helm install creates versioned releases to deploy, configure and update containerized apps.

Blue-green deployment diagram: two identical production environments (blue and green) with load balancer switching traffic for zero-downtime releases and fast rollback on failures.

Diagram showing continuous testing in DevOps: automated unit, integration, and E2E tests in CI/CD pipeline; test environments, test data management, monitoring, and feedback loops.

Ansible configuration management workflow: set up control node, define inventory, write playbooks & roles, manage variables, secure SSH keys, run idempotent ansible-playbook tests.

GitOps workflow diagram: devs push code to Git; CI builds images; declarative manifests in repo drive automated CD to clusters; monitoring, alerts and Git-based rollback. in GitOps
