This curriculum spans the technical breadth of a multi-workshop server operations program, addressing the same configuration, automation, and compliance challenges encountered in enterprise infrastructure modernization and hybrid cloud migration projects.
Module 1: Server Infrastructure Planning and Sizing
- Selecting physical vs. virtual server deployment based on application I/O requirements and compliance constraints.
- Determining CPU core allocation for database-backed applications under peak concurrency loads.
- Calculating memory overcommit ratios in virtualized environments while maintaining application responsiveness.
- Designing storage tiering strategies using SSD and HDD combinations for cost-performance balance.
- Planning network bandwidth requirements for inter-server communication in clustered applications.
- Documenting server naming conventions and IP address allocation to support audit and change management.
Module 2: Operating System Configuration and Hardening
- Disabling unused services and ports on Linux/Windows servers to reduce attack surface.
- Implementing role-based access control (RBAC) for administrative accounts using group policies or sudo rules.
- Configuring secure boot and UEFI settings to prevent unauthorized firmware modifications.
- Applying CIS benchmarks and validating compliance using automated scanning tools.
- Scheduling and testing OS patching windows to minimize disruption to business-critical applications.
- Managing kernel parameters (e.g., file handles, network buffers) to support high-throughput applications.
Module 3: Application Deployment and Runtime Management
- Configuring application server environments (e.g., Tomcat, IIS) with correct JVM or .NET runtime versions.
- Setting environment-specific configuration files without exposing credentials in source control.
- Managing application dependencies using isolated virtual environments or containers.
- Implementing health checks and startup probes for applications in orchestrated environments.
- Rotating application log files and defining retention policies to prevent disk exhaustion.
- Validating application startup sequence dependencies with database and message queue services.
Module 4: Monitoring, Alerting, and Performance Tuning
- Deploying agent-based monitoring tools to collect CPU, memory, and disk I/O metrics at 15-second intervals.
- Defining alert thresholds for response time degradation that differentiate between noise and incidents.
- Correlating application error logs with server resource utilization to isolate performance bottlenecks.
- Using APM tools to trace transaction latency across multiple server tiers and microservices.
- Generating monthly performance reports to justify hardware upgrades or optimization efforts.
- Configuring synthetic transactions to monitor critical user workflows proactively.
Module 5: High Availability and Disaster Recovery
- Designing active-passive vs. active-active server clusters based on RTO and RPO requirements.
- Configuring shared storage and quorum settings in Windows Failover Clustering or Pacemaker.
- Testing failover procedures for database and application servers in non-production environments.
- Replicating server configurations using configuration management tools across DR sites.
- Scheduling and validating full system backups including application state and configuration files.
- Documenting recovery runbooks with precise command sequences and escalation paths.
Module 6: Security and Compliance Enforcement
- Integrating servers into centralized identity providers (e.g., LDAP, Active Directory) for authentication.
- Enforcing encrypted communication (TLS 1.2+) between application servers and clients.
- Implementing file integrity monitoring for critical system and application binaries.
- Generating audit logs for privileged command execution and forwarding them to SIEM systems.
- Conducting quarterly access reviews to remove orphaned or excessive user permissions.
- Aligning server configurations with regulatory standards such as HIPAA, PCI-DSS, or SOX.
Module 7: Automation and Configuration Management
- Authoring Ansible playbooks or Puppet manifests to standardize web server configurations.
- Using immutable server patterns in cloud environments to eliminate configuration drift.
- Integrating configuration management with CI/CD pipelines for zero-touch deployments.
- Managing secrets using HashiCorp Vault or AWS Systems Manager Parameter Store.
- Version-controlling server configurations in Git and enforcing peer review for changes.
- Rolling out configuration updates in canary batches to detect unintended side effects.
Module 8: Cloud and Hybrid Server Operations
- Selecting appropriate cloud instance types based on application memory and compute profiles.
- Establishing secure site-to-site VPN or Direct Connect links between on-prem and cloud VPCs.
- Implementing auto-scaling groups with custom metrics to handle variable application loads.
- Managing hybrid DNS resolution between on-premises and cloud-hosted services.
- Monitoring cloud spending on server instances and identifying underutilized resources.
- Applying consistent security group and network ACL policies across hybrid environments.
