This curriculum spans the technical and procedural rigor of a multi-workshop infrastructure modernization program, covering the same depth of operational discipline applied in enterprise-scale cloud migrations and internal platform engineering initiatives.

Module 1: Infrastructure Planning and Environment Segregation

• Selecting appropriate server instance types based on application load profiles and cost-performance trade-offs across development, staging, and production environments.
• Designing network segmentation to isolate environments while enabling controlled data flow for testing and monitoring.
• Implementing consistent naming conventions and tagging strategies for cloud resources to support billing, automation, and audit compliance.
• Deciding between containerized versus bare-metal deployments for latency-sensitive or compliance-bound applications.
• Establishing quotas and limits on non-production environments to prevent resource sprawl and cost overruns.
• Integrating environment provisioning into CI/CD pipelines while maintaining manual approval gates for production deployment.
• Documenting hardware and software dependencies for legacy integrations that constrain infrastructure choices.
• Planning for regional failover by replicating critical environments in geographically distributed zones.

Module 2: Configuration Management and Infrastructure as Code

• Choosing between declarative (e.g., Terraform) and imperative (e.g., Ansible) tools based on team expertise and rollback requirements.
• Versioning configuration templates and aligning them with application release cycles to prevent drift.
• Managing secrets in IaC pipelines using dedicated vault integrations instead of environment variables or config files.
• Enforcing peer review of infrastructure changes through pull request workflows in version control.
• Handling state file management for Terraform in team environments using remote backends with locking mechanisms.
• Automating drift detection and reconciliation for production servers that may have been modified outside of IaC.
• Standardizing OS images using Packer to reduce configuration variance across server fleets.
• Defining reusable modules for common components like load balancers or database proxies to ensure consistency.

Module 3: Patch Management and System Updates

• Scheduling maintenance windows for patching that minimize disruption to user-facing services and third-party integrations.
• Testing security patches in a mirrored staging environment before rollout to production.
• Implementing automated patch compliance reporting to meet internal audit and regulatory requirements.
• Choosing between rolling updates and blue-green replacement for minimizing downtime during kernel or library upgrades.
• Managing dependencies when updating system libraries that may break application compatibility.
• Configuring unattended-upgrades selectively to apply only security patches on critical systems.
• Documenting rollback procedures for failed updates, including snapshot restoration and configuration reversion.
• Coordinating with development teams to avoid patching during active deployment cycles.

Module 4: Monitoring, Logging, and Alerting

• Defining baseline performance metrics (CPU, memory, disk I/O) for each service to detect anomalies.
• Configuring log retention policies that balance storage costs with forensic investigation needs.
• Filtering and parsing application logs to extract structured error events for alerting systems.
• Setting threshold-based alerts with hysteresis to reduce false positives from transient spikes.
• Integrating APM tools with custom instrumentation to trace latency across microservices.
• Centralizing logs using secure transport (e.g., TLS) from distributed servers to a SIEM platform.
• Creating service-level dashboards that reflect business KPIs rather than just technical metrics.
• Validating alert delivery paths (SMS, email, PagerDuty) through periodic test incidents.

Module 5: Backup, Recovery, and Disaster Planning

• Classifying data by recovery point and recovery time objectives to determine backup frequency and method.
• Encrypting backup data at rest and in transit, with access restricted to authorized personnel only.
• Testing full-system recovery from backups in an isolated environment at least quarterly.
• Storing backups in geographically separate regions to mitigate data center outages.
• Automating backup validation by checksum verification and file integrity checks.
• Documenting recovery runbooks with step-by-step procedures for different failure scenarios.
• Coordinating backup schedules to avoid resource contention during peak application usage.
• Managing retention periods for backups in accordance with data privacy regulations (e.g., GDPR, HIPAA).

Module 6: Security Hardening and Access Control

• Disabling root SSH access and enforcing key-based authentication with multi-factor for administrative access.
• Implementing role-based access control (RBAC) for server management tools based on job function.
• Applying the principle of least privilege when granting sudo permissions to developers and operators.
• Configuring host-based firewalls to restrict inbound and outbound traffic to required ports only.
• Rotating SSH keys and service account credentials on a scheduled basis or after personnel changes.
• Conducting regular vulnerability scans and remediating findings based on severity and exploitability.
• Enabling audit logging for privileged commands and monitoring for anomalous behavior.
• Hardening OS configurations using CIS benchmarks or internal security baselines.

Module 7: Performance Tuning and Resource Optimization

• Profiling application bottlenecks using system tools (e.g., top, iostat, netstat) to guide infrastructure adjustments.
• Adjusting kernel parameters (e.g., file descriptor limits, TCP buffer sizes) for high-throughput services.
• Right-sizing virtual machines based on actual utilization trends rather than peak theoretical loads.
• Implementing caching layers (e.g., Redis, Varnish) to reduce backend server load and response latency.
• Monitoring swap usage to detect memory pressure and prevent performance degradation.
• Optimizing database connection pooling to prevent exhaustion of server resources.
• Using autoscaling policies based on custom metrics rather than generic CPU thresholds.
• Identifying and terminating orphaned processes or zombie containers consuming system resources.

Module 8: Change Management and Operational Governance

• Requiring change tickets for all production modifications, including emergency fixes with post-incident review.
• Conducting blameless postmortems for outages to identify systemic issues and prevent recurrence.
• Maintaining an up-to-date configuration management database (CMDB) to track server ownership and purpose.
• Enforcing change freeze periods during critical business cycles (e.g., end-of-quarter, Black Friday).
• Requiring dual approval for high-risk operations such as database migrations or firewall rule changes.
• Archiving decommissioned servers only after confirming all dependencies have been removed.
• Standardizing incident response workflows with escalation paths and communication protocols.
• Conducting regular operational reviews to assess tooling effectiveness and process adherence.

Module 9: Integration with Development Workflows

• Providing developers with self-service tools to spin up isolated test environments with production-like configurations.
• Enforcing pre-deployment checks in CI pipelines for configuration compliance and security scanning.
• Instrumenting servers to expose health endpoints consumed by Kubernetes liveness and readiness probes.
• Collaborating with developers to define resource requests and limits in container manifests.
• Sharing performance and error metrics with development teams to inform optimization efforts.
• Documenting server dependencies and API contracts to prevent breaking changes during maintenance.
• Automating the cleanup of ephemeral environments to prevent resource leakage.
• Establishing feedback loops between operations and development to refine observability requirements.
