This interactive mind map shows how 19 DevOps tools — Docker, Kubernetes, Terraform, Jenkins, Prometheus, ArgoCD, AWS, and more — connect in real-world production workflows. Understanding these connections is what separates strong DevOps and SRE candidates in technical interviews. Click any node to explore its use cases, key commands, architecture patterns, and real interview questions.
In a modern engineering organisation, these tools form an end-to-end automated pipeline. A developer pushes code to Git. GitHub Actions or Jenkins automatically builds the application, runs unit tests, performs static code analysis with SonarQube, checks for vulnerable dependencies with OWASP Dependency-Check, builds a Docker image, and scans it with Trivy for known CVEs. The validated image is pushed to JFrog Artifactory with full build traceability metadata.
ArgoCD then detects the new image tag committed to the GitOps repository and syncs the updated configuration to the Kubernetes cluster. Kubernetes orchestrates the rolling deployment across nodes, using liveness and readiness probes to ensure only healthy pods receive traffic. HashiCorp Vault injects secrets into pods at runtime — no credentials are stored in images or repositories.
Once deployed, Prometheus scrapes metrics every 15 seconds and Grafana visualises them in dashboards. Alertmanager fires notifications when SLO burn rates exceed thresholds — for example, when error rate is consuming the monthly error budget at 14x the sustainable rate. Splunk aggregates logs for compliance, forensics, and security correlation. Terraform manages all underlying AWS and Azure infrastructure as versioned, reviewable code.
