Serverless Architectures on AWS, Second Edition

10 Blackbelt Lambda

This chapter covers

• Monitoring latency, request per second, and concurrency for serverless applications
• Techniques for optimizing latency

Performance (how fast your application responds) and availability (whether or not your application provides a valid response) are critical aspects of your end user experience. When using serverless architectures, your performance also has a direct impact on your costs; for example, AWS Lambda bills you for the duration your function runs, weighted by the memory you assign to it. Serverless architectures eliminate many of the common surface areas for performance optimizations, like scaling available servers or tweaking server configurations, which can make it challenging for new users to ...
