Description

This curriculum spans the design and operationalisation of deployment automation systems across multi-environment enterprise landscapes, comparable in scope to a multi-workshop internal capability program for standardising DevOps practices across cloud platforms, security frameworks, and compliance regimes.

Module 1: Evaluating and Selecting Deployment Automation Tools

Compare agent-based versus agentless architectures when assessing tools like Ansible, Puppet, and SaltStack for network and security constraints.
Assess vendor lock-in risks when choosing cloud-native deployment tools versus open-source, cross-platform solutions.
Determine tool compatibility with existing CI/CD pipelines by evaluating API maturity and plugin ecosystems.
Balance learning curve and team expertise when selecting declarative (e.g., Terraform) versus imperative (e.g., Shell/Python scripts) approaches.
Validate support for immutable infrastructure patterns in candidate tools for stateless application deployments.
Conduct proof-of-concept testing across multiple environments (dev, staging, prod) to evaluate idempotency and drift detection capabilities.

Module 2: Infrastructure as Code (IaC) Design and Implementation

Structure Terraform modules to enforce reusability and environment isolation using workspaces or backend configurations.
Implement dynamic block constructs in Terraform to manage conditional resource configurations without duplication.
Enforce naming conventions and tagging standards in IaC templates to support cost allocation and compliance audits.
Manage state file security by configuring remote backends with encryption and access controls, avoiding local state in team environments.
Resolve state drift by defining reconciliation policies and determining whether to automate correction or require manual approval.
Version control IaC configurations with semantic versioning and integrate with pull request workflows to prevent unreviewed changes.

Module 3: Secure Deployment Pipeline Design

Integrate secret scanning tools into CI pipelines to detect and block hardcoded credentials in deployment scripts.
Rotate and inject secrets at runtime using tools like HashiCorp Vault or AWS Secrets Manager instead of storing them in configuration files.
Enforce role-based access control (RBAC) on deployment tools to limit production environment access to authorized personnel only.
Sign and verify deployment artifacts using GPG or cosign to ensure integrity from build to deployment.
Implement pipeline gating with automated security policy checks using Open Policy Agent (OPA) or Sentinel.
Audit all deployment actions by forwarding tool logs to a centralized SIEM system with immutable storage.

Module 4: Blue-Green and Canary Deployment Strategies

Configure load balancer routing rules to shift traffic incrementally between blue and green environments during cutover.
Automate health check validation before promoting a canary release to 100% traffic.
Design rollback procedures that revert configuration changes and traffic routing within defined SLA timeframes.
Instrument application metrics to detect performance degradation in canary instances using Prometheus and Alertmanager.
Coordinate database schema changes with deployment strategy to avoid incompatibility during blue-green transitions.
Simulate production traffic on staging environments to validate routing and scaling behavior before live deployment.

Module 5: Managing State and Configuration Drift

Configure periodic reconciliation jobs in Puppet or Chef to detect and report configuration deviations from desired state.
Define remediation policies for drift: auto-correct non-critical settings, alert on critical system file changes.
Use drift detection tools like AWS Config or Terraformer to audit cloud resource configurations against IaC baselines.
Implement immutable server patterns to reduce drift by replacing instances instead of modifying them in-place.
Document approved configuration exceptions and exempt specific resources from automated enforcement.
Integrate drift reports into incident management systems to trigger investigation workflows for unauthorized changes.

Module 6: Scaling and Orchestrating Deployments Across Environments

Parameterize deployment templates to support environment-specific configurations without code duplication.
Use deployment orchestration tools like Spinnaker to manage complex workflows across multiple regions and cloud providers.
Implement parallel deployment strategies for microservices to reduce overall release time while managing dependency order.
Throttle deployment concurrency to avoid overwhelming shared resources like databases or message queues.
Coordinate cross-team deployments using dependency mapping and scheduling tools to prevent conflicts.
Validate environment parity by comparing configuration and topology between staging and production using automated checks.

Module 7: Monitoring, Feedback Loops, and Post-Deployment Validation

Integrate deployment markers into monitoring dashboards to correlate performance changes with release events.
Automate post-deployment smoke tests that validate core functionality before marking a release as successful.
Configure alerts on error rate spikes or latency increases immediately following a deployment.
Collect and analyze deployment failure root causes to refine rollback thresholds and pre-deployment checks.
Feed deployment success/failure metrics into team retrospectives to improve process reliability.
Expose deployment health metrics to business stakeholders via SLI dashboards to align technical outcomes with service goals.

Module 8: Governance, Compliance, and Change Management

Enforce change advisory board (CAB) approvals for production deployments using pipeline gating and ticketing system integration.
Map deployment activities to ITIL change records to satisfy audit and compliance requirements.
Implement automated compliance checks for regulatory standards (e.g., HIPAA, PCI-DSS) within deployment pipelines.
Archive deployment manifests and logs for retention periods required by internal policy or legal jurisdiction.
Standardize deployment procedures across teams to reduce variability and increase auditability.
Conduct periodic access reviews for deployment tool credentials and permissions to enforce least privilege.
