This curriculum spans the design and governance of production-grade DevOps workflows at the scale of multi-team platform engineering programs, covering the technical, procedural, and coordination challenges typical in regulated or large-scale software organisations.

Module 1: Infrastructure as Code (IaC) Design and Governance

  • Select between declarative (e.g., Terraform) and imperative (e.g., Ansible) IaC tools based on team expertise and change control requirements.
  • Implement module versioning in Terraform to prevent breaking changes across environments during parallel development.
  • Enforce IaC peer review policies using mandatory pull requests and automated policy checks via Open Policy Agent (OPA).
  • Balance state file security and accessibility by choosing between remote backends (e.g., S3 with state locking) and local state with access controls.
  • Design reusable IaC modules with input validation and output standardization to support multi-team adoption.
  • Integrate drift detection into CI/CD pipelines to identify and remediate configuration deviations from source-controlled templates.

Module 2: CI/CD Pipeline Architecture and Optimization

  • Decide between monorepo and polyrepo pipeline designs based on team autonomy, release cadence, and dependency management needs.
  • Implement pipeline parallelization and selective job triggering to reduce feedback time in large codebases.
  • Configure artifact retention policies in Nexus or Artifactory to balance storage costs with audit and rollback requirements.
  • Enforce pipeline immutability by signing and versioning pipeline definitions in source control.
  • Integrate canary analysis into deployment stages using metrics from Prometheus and logs from Loki to gate progression.
  • Design pipeline rollback mechanisms that include artifact reversion, configuration reset, and database migration rollback coordination.

Module 3: Secure Software Supply Chain

  • Enforce SBOM (Software Bill of Materials) generation at build time and integrate into vulnerability scanning workflows.
  • Implement signed commits and artifact signing using Sigstore or Notary to prevent unauthorized code injection.
  • Configure dependency scanning tools (e.g., Dependabot, Snyk) with policy thresholds that align with risk tolerance and remediation capacity.
  • Isolate build environments using ephemeral runners with minimal privileges to reduce attack surface.
  • Integrate attestations into the pipeline using in-toto or Cosign to verify build provenance and integrity.
  • Define and enforce admission controls for container images in the registry using OPA or Kyverno policies.

Module 4: Observability and Telemetry Integration

  • Standardize log structure across services using structured logging formats (e.g., JSON) and enforce schema compliance.
  • Configure distributed tracing with context propagation across microservices using OpenTelemetry instrumentation.
  • Balance metric granularity and cardinality to prevent Prometheus series explosion while maintaining diagnostic utility.
  • Implement synthetic monitoring for critical user journeys to detect degradation before real-user impact.
  • Design alerting rules with actionable thresholds and clear runbook references to reduce mean time to resolution.
  • Aggregate and correlate telemetry data across logs, metrics, and traces in a centralized observability platform for root cause analysis.

Module 5: Production Deployment Strategies

  • Select deployment strategy (blue-green, canary, rolling) based on risk profile, rollback requirements, and infrastructure constraints.
  • Coordinate database schema changes with application deployments using versioned migration scripts and backward compatibility.
  • Implement feature flags with kill switches to decouple deployment from release and enable controlled rollouts.
  • Configure traffic shifting in service mesh (e.g., Istio) or API gateway to support gradual canary promotions.
  • Design health check endpoints that reflect actual service dependencies and readiness for traffic routing.
  • Validate deployment success using automated smoke tests and performance benchmarks before full cutover.

Module 6: Incident Response and Postmortem Culture

  • Define incident severity levels with clear escalation paths and communication protocols for on-call teams.
  • Integrate incident management tools (e.g., PagerDuty, Opsgenie) with monitoring systems to automate alert routing.
  • Conduct blameless postmortems with structured templates that document timeline, contributing factors, and action items.
  • Track remediation tasks from postmortems in a public backlog to ensure accountability and follow-through.
  • Implement runbook automation for common incident scenarios to reduce cognitive load during outages.
  • Rotate on-call responsibilities with training and shadowing to maintain team resilience and knowledge sharing.

Module 7: Compliance, Auditing, and Change Management

  • Map CI/CD pipeline stages to audit controls (e.g., SOC 2, ISO 27001) and generate evidence artifacts automatically.
  • Implement change advisory board (CAB) workflows for high-risk production changes using automated approval gates.
  • Log all pipeline executions and configuration changes to immutable storage for forensic analysis.
  • Enforce separation of duties by restricting production deployment permissions to designated roles and requiring dual approvals.
  • Integrate configuration management database (CMDB) updates into deployment pipelines to maintain accurate asset inventory.
  • Conduct periodic access reviews for pipeline and infrastructure permissions to enforce least privilege.

Module 8: Scaling DevOps Across Multiple Teams and Environments

  • Design platform teams to provide self-service tooling (e.g., internal developer platforms) while maintaining security and compliance guardrails.
  • Standardize environment provisioning using environment templates to reduce configuration drift.
  • Implement multi-region deployment patterns with failover testing to meet disaster recovery objectives.
  • Manage cross-team dependencies using contract testing and consumer-driven contracts in integration pipelines.
  • Balance centralization and decentralization by defining clear ownership boundaries for shared services and tooling.
  • Measure and report on DORA metrics consistently across teams to identify bottlenecks and track improvement initiatives.
