Execution includes CloudWatch Events, rate expressions, and error notifications that automate operations while eliminating infrastructure through scheduled serverless tasks.
Real time File Processing
Responsive Charleston systems trigger functions on S3 uploads processing images, documents, or data files immediately without polling. Processing includes thumbnail generation, data validation, and ETL operations that react instantly while scaling automatically through event driven file processing.
Performance Optimization
Cold Start Mitigation
Charleston performance optimization reduces cold starts through provisioned concurrency, runtime selection, and function warming achieving consistent sub second response times. Mitigation includes lightweight functions, connection pooling, and strategic warming that ensure responsiveness while managing costs through cold start reduction strategies.
Memory and CPU Tuning
Optimized Charleston functions balance memory allocation with execution time finding sweet spots that minimize cost while meeting performance requirements. Tuning includes profiling tools, cost calculators, and performance testing that optimize resources while controlling expenses through careful capacity planning.
Concurrent Execution Limits
Scaled Charleston deployments manage concurrent execution limits preventing downstream service overload while ensuring fair resource allocation. Limits include reserved concurrency, throttling strategies, and queue integration that control load while maintaining availability through concurrency management approaches.
Caching Strategies
