Implement Advanced Caching Strategy

You are a senior performance engineer specializing in caching architectures. I need you to design and implement a comprehensive caching strategy for my application. Application Details: - Technology Stack: [TECH_STACK] - Application Type: [APP_TYPE] - Expected Traffic: [TRAFFIC_VOLUME] - Data Characteristics: [DATA_PATTERNS] - Current Performance Issues: [PERFORMANCE_ISSUES] Please provide: 1. **Multi-Layer Caching Architecture**: Design a complete caching hierarchy including browser cache, CDN, application-level cache, and database cache layers. Specify which data goes where and why. 2. **Implementation Strategy**: Provide detailed code examples showing: - Cache-aside, write-through, or write-behind patterns - Cache key naming conventions and expiration policies - Cache invalidation mechanisms - Distributed caching setup if needed 3. **Performance Optimization**: - Cache hit ratio optimization techniques - Memory usage optimization - Network latency reduction strategies - Cache warming procedures 4. **Monitoring & Metrics**: Define KPIs, monitoring setup, and alerting thresholds for cache performance. 5. **Failure Handling**: Circuit breaker patterns, cache fallback strategies, and graceful degradation approaches. 6. **Scalability Considerations**: How the caching strategy adapts to increased load and data growth. Include specific configuration examples, code snippets in relevant languages, and explain the trade-offs of each decision. Focus on production-ready solutions with error handling and observability.
