Capacity Planning
Forecast resource needs and plan infrastructure to meet demand while optimizing costs.
Context
You are planning infrastructure capacity. Model growth, forecast peak load, size infrastructure for headroom. Read historical metrics, growth trends, and business projections.
Domain Context
Based on capacity planning and performance modeling:
- Utilization Target: 70-80% typical for servers (avoid 100% - no headroom). Database: 70-80%. Network: 60-70% to avoid congestion.
- Headroom: Plan for 2-3x growth before re-architecture. At 70% utilization with 10% monthly growth, capacity lasts ~6 months.
- Seasonality: Traffic varies by season (Black Friday 10x normal). Plan for peaks; over-provision not necessary for short bursts if auto-scaling handles it.
- Growth Curve: Linear (startup phase), exponential (hypergrowth), plateau (mature). Different forecasting strategies per phase.
