Cache Types
Full Page Cache (FPC)
- Varnish Configuration: Expert Varnish configuration and VCL optimization
- Built-in FPC: Optimize Magento's built-in full-page cache
- ESI Implementation: Implement Edge Side Includes for dynamic content
- Cache Warming: Automated cache warming and preloading strategies
- Cache Tags: Proper cache tag implementation for invalidation
Application Cache
- Block Cache: Cache rendered blocks for faster page generation
- Configuration Cache: Cache system and module configurations
- Layout Cache: Cache layout XML structures
- Collection Cache: Cache frequently accessed collections
- Object Cache: Cache expensive object instantiation
Distributed Caching
- Redis: High-performance in-memory data store
- Memcached: Distributed memory caching system
- Multi-tier Caching: Layer caching for optimal performance
- Cache Synchronization: Maintain cache consistency across servers
- Failover Strategies: Implement cache failover and recovery
Cache Optimization Process
1. Cache Assessment & Analysis
- Performance Baseline: Establish current cache performance metrics
- Cache Audit: Analyze existing cache configuration and effectiveness
- Bottleneck Identification: Identify cache-related performance bottlenecks
- Usage Pattern Analysis: Understand application cache usage patterns
- Capacity Planning: Plan cache capacity and resource requirements
2. Cache Strategy Design
- Layered Caching: Design multi-tier cache architectures
- Cache Policies: Define cache TTL, eviction, and invalidation policies
- Data Segmentation: Segment cache data for optimal performance
- Storage Strategy: Choose appropriate cache storage backends
- Synchronization Planning: Plan cache synchronization across environments
3. Implementation & Configuration
Redis Configuration
// app/etc/env.php

'backend' => 'Cm_Cache_Backend_Redis',
'backend_options' => [
'server' => '127.0.0.1',
'port' => '6379',
'database' => '0',
]
