Reusable architecture patterns for reliable, scalable systems.

Planned Patterns

Reliability

☐ Circuit breaker
☐ Retry with exponential backoff
☐ Bulkhead isolation
☐ Graceful degradation
☐ Health checks

Scalability

☐ Horizontal pod autoscaling
☐ Database sharding
☐ CQRS
☐ Event sourcing
☐ Cache-aside

Deployment

☐ Blue-green deployment
☐ Canary deployment
☐ Feature flags
☐ Database migrations

Observability

☐ Structured logging
☐ Distributed tracing
☐ SLO-based alerting
☐ Dashboard templates

Structure

Each pattern includes:

Problem statement
Solution overview
Implementation guide
Code examples
Trade-offs
When to use / when not to use

blind-search-ratchet-minecraft-beats-itself — a Minecraft simulation finished after about 1.975 billion simulated years because destroyed crystals stayed destroyed. Retained progress adds stage times, lost progress multiplies them, the last stage dominates, and a single run says little about the typical total. (2026-10-01)
