This curriculum spans the technical and operational rigor of a multi-workshop infrastructure modernization program, addressing the same private cloud and DevOps integration challenges typically tackled in enterprise advisory engagements.
Module 1: Defining Private Cloud Architecture for DevOps Integration
- Selecting hypervisor technology (e.g., VMware vSphere vs. KVM) based on existing virtualization expertise and support requirements.
- Designing network segmentation using VLANs or VXLANs to isolate development, staging, and production environments.
- Implementing centralized identity management via LDAP/Active Directory integration for consistent access control.
- Deciding between converged vs. hyper-converged infrastructure based on scalability and operational maintenance constraints.
- Allocating resource pools with reservations and limits to prevent noisy neighbor issues across teams.
- Establishing tagging standards for VMs and containers to enable cost tracking and lifecycle automation.
Module 2: Infrastructure as Code (IaC) Implementation at Scale
- Choosing between Terraform and proprietary tools (e.g., vRealize Automation) based on multi-cloud readiness and team proficiency.
- Structuring Terraform modules to support environment promotion (dev → test → prod) with minimal duplication.
- Managing state files securely using remote backends with role-based access and audit logging.
- Enforcing IaC standards through pre-commit hooks and CI pipeline validation using tools like Checkov or tflint.
- Versioning infrastructure configurations in Git with branching strategies aligned to release cycles.
- Handling drift detection and reconciliation policies when manual changes bypass IaC workflows.
Module 3: CI/CD Pipeline Integration with Private Cloud Resources
- Provisioning ephemeral build environments per pipeline run to ensure isolation and repeatability.
- Configuring Jenkins or GitLab runners on dedicated VMs with constrained resource quotas.
- Integrating artifact promotion with VM image baking using Packer in a signed and scanned workflow.
- Managing secrets for pipeline jobs using HashiCorp Vault with short-lived credentials.
- Orchestrating blue-green deployments of VM-based applications using load balancer reconfiguration scripts.
- Enabling pipeline rollback by maintaining versioned OVA templates in a private image repository.
Module 4: Container Orchestration and Hybrid Workload Management
- Deploying Kubernetes clusters on private cloud VMs using Rancher or Tanzu, including CNI and CSI plugin selection.
- Integrating container registries (e.g., Harbor) with image scanning and admission control policies.
- Configuring node autoscaling based on cluster utilization while respecting private cloud resource quotas.
- Managing persistent storage for stateful workloads using NFS-backed PVs or enterprise storage integrations.
- Enforcing network policies to restrict pod-to-pod communication across namespaces.
- Maintaining hybrid deployments where some services run in containers and others on traditional VMs.
Module 5: Security and Compliance Governance
- Implementing firewall rules at the hypervisor and guest level using distributed firewalls or NSX.
- Conducting regular VM and container image vulnerability scans integrated into patch management workflows.
- Enforcing encryption of VM disks and container registry artifacts using KMS-integrated solutions.
- Designing audit trails for administrative actions via vCenter logging and SIEM integration.
- Applying least-privilege access controls for self-service portals using RBAC tied to AD groups.
- Aligning VM provisioning workflows with compliance frameworks (e.g., SOC 2, HIPAA) through policy-as-code checks.
Module 6: Monitoring, Logging, and Performance Optimization
- Deploying centralized logging agents (e.g., Fluentd, Filebeat) across VMs and containers with log retention policies.
- Configuring Prometheus and Grafana for monitoring VM and Kubernetes cluster health with alerting thresholds.
- Correlating infrastructure metrics with application performance data using distributed tracing.
- Setting up synthetic transaction monitoring to detect degradation in private cloud-hosted services.
- Allocating monitoring resources on dedicated VMs to avoid impacting production workloads.
- Establishing baseline performance profiles for VM templates to detect configuration drift or resource bottlenecks.
Module 7: Disaster Recovery and Business Continuity Planning
- Designing VM replication schedules and RPOs between primary and secondary private cloud sites.
- Testing failover procedures for critical applications without disrupting production traffic.
- Automating backup validation through scripted restoration of database snapshots in isolated environments.
- Integrating DNS and load balancer reconfiguration into failover runbooks.
- Documenting recovery priorities and dependencies for interdependent DevOps services.
- Maintaining offline backups of encryption keys and configuration repositories for air-gapped recovery.
Module 8: Operational Governance and Cost Management
- Implementing chargeback or showback models using tagging and resource usage telemetry from vCenter.
- Setting automated shutdown policies for non-production VMs during off-hours to reduce resource consumption.
- Establishing VM lifecycle policies with automated decommissioning after inactivity thresholds.
- Conducting quarterly architecture reviews to identify underutilized VMs and over-provisioned resources.
- Managing software licensing costs for guest OS and middleware in dynamically provisioned environments.
- Developing escalation paths and SLAs for infrastructure support teams handling DevOps team requests.
