Application Profiling Solutions

Application profiling giúp:

• Identify resource usage
• Baseline application performance
• Visualize in real-time (dashboards, maps)
• Find performance improvements

Key AWS Services

• Amazon CodeGuru - Profile application, visualize profiling data, identify performance improvements
• AWS Lambda Power Tuning - Automate memory/compute optimization, graph results
• AWS Compute Optimizer - Identify optimal EC2 instance types, EBS volumes, Lambda memory sizes
• Amazon EMR - Process large amounts of data
• CloudFront - Cache content, optimize availability
• ElastiCache - In-memory caching
• DynamoDB Streams - Capture data modifications
