Description

This curriculum spans the technical and organizational practices found in multi-workshop capacity planning programs, covering demand forecasting, performance modeling, ITSM integration, and cloud governance comparable to those in enterprise advisory engagements and internal platform engineering initiatives.

Module 1: Defining Capacity Requirements and Demand Forecasting

Select service workloads to monitor based on business criticality and historical incident frequency to prioritize capacity modeling efforts.
Integrate business workload projections from finance and product teams into capacity models, reconciling discrepancies between IT assumptions and business plans.
Choose between time-series forecasting and regression-based models depending on data availability and stability of demand patterns.
Establish thresholds for acceptable forecast error rates and define escalation paths when projections deviate beyond tolerance.
Map application-level transaction volumes to infrastructure metrics (e.g., CPU per 1,000 API calls) to translate business demand into technical load.
Document assumptions in demand models and update them quarterly or after major business changes to maintain accuracy.

Module 2: Performance Baselines and Resource Profiling

Define baseline performance for critical systems using 95th percentile utilization over a four-week period to exclude outliers.
Segment resource consumption by tenant, application, or business unit when shared platforms support multiple stakeholders.
Identify performance bottlenecks by correlating response time degradation with concurrent increases in specific resource usage (e.g., disk I/O).
Standardize profiling intervals (e.g., weekly snapshots) to enable trend analysis and detect gradual performance decay.
Exclude maintenance windows and patching periods from baseline calculations to prevent skewing normal operating profiles.
Use synthetic transaction monitoring to isolate infrastructure performance from variable user behavior in baseline creation.

Module 3: Modeling and Simulation of Capacity Scenarios

Select modeling tools based on integration capabilities with existing monitoring systems and support for what-if scenario branching.
Simulate peak load scenarios using stress-test data from pre-production environments to validate model accuracy.
Adjust simulation parameters to reflect planned architectural changes, such as migration to microservices or adoption of caching layers.
Quantify the impact of redundancy requirements (e.g., active-active clusters) on total capacity needs and cost implications.
Model failure scenarios to determine spare capacity required for failover without breaching SLAs.
Validate simulation outputs against real-world incidents where capacity constraints caused service degradation.

Module 4: Integrating Capacity Data with ITSM Processes

Link capacity thresholds to incident management by triggering high-severity incidents when utilization exceeds 90% for more than 15 minutes.
Feed capacity forecasts into change advisory board (CAB) reviews to assess the infrastructure impact of proposed changes.
Embed capacity risk ratings in service design documents to influence architectural decisions during service transition.
Align capacity review cycles with service level review meetings to ensure business stakeholders are informed of risks.
Automate ticket creation for capacity remediation tasks when thresholds are breached, assigning to responsible engineering teams.
Map capacity constraints to known error databases to prevent repeated incident resolution for resource-related outages.

Module 5: Right-Sizing and Resource Optimization

Conduct quarterly rightsizing reviews for virtual machines, adjusting CPU and memory allocations based on utilization trends.
Decide between vertical and horizontal scaling based on application architecture and operational support constraints.
Implement auto-scaling policies with cooldown periods to prevent thrashing during transient load spikes.
Negotiate reserved instance commitments in cloud environments only after validating sustained utilization over six months.
Decommission underutilized systems with documented approval from business owners to prevent resource hoarding.
Balance optimization efforts against stability risks, avoiding aggressive downsizing in mission-critical, low-tolerance environments.

Module 6: Capacity Governance and Stakeholder Alignment

Establish capacity review boards with representation from infrastructure, application, and business units to prioritize investments.
Define ownership of capacity outcomes per service, assigning accountability for monitoring and remediation.
Set escalation paths for capacity risks that cannot be resolved within standard change windows or budget cycles.
Document capacity-related SLAs and SLOs in service catalogs, including response times under defined load conditions.
Balance cost containment objectives with performance requirements when stakeholders demand aggressive optimization.
Report capacity health using standardized dashboards accessible to technical and non-technical stakeholders.

Module 7: Monitoring, Alerting, and Continuous Improvement

Configure dynamic thresholds for alerts based on time-of-day and day-of-week patterns to reduce false positives.
Integrate capacity metrics into AIOps platforms to correlate resource constraints with incident clusters.
Define alert suppression rules during scheduled batch processing to avoid alert fatigue.
Conduct root cause analysis on capacity-related incidents to update models and prevent recurrence.
Rotate capacity monitoring responsibilities across team members to maintain operational familiarity and reduce single points of failure.
Update capacity plans biannually or after major infrastructure changes, incorporating lessons from incident retrospectives.

Module 8: Cloud and Hybrid Environment Considerations

Track egress bandwidth costs in multi-cloud designs and factor them into capacity decisions for data-intensive workloads.
Implement tagging standards for cloud resources to enable accurate cost and utilization attribution by department or project.
Design burst capacity strategies using spot instances or serverless functions while assessing reliability trade-offs.
Monitor API rate limits and service quotas in public cloud platforms to prevent operational disruption during scaling events.
Align private data center refresh cycles with cloud migration roadmaps to avoid stranded investments.
Use cloud-native capacity tools (e.g., AWS Compute Optimizer) alongside enterprise monitoring systems to validate recommendations.
