Amazon CloudWatch Evidently adds support for Client Side Evaluations (CSE) for AWS Lambda, powered by AWS AppConfig. Evidently is an application performance monitoring (APM) capability that makes it easier for customers to introduce experiments and launches in their application code. Powered by AppConfig Extensions, Evidently CSE allows application developers to generate feature-evaluations in single-digit milliseconds from within their own Lambda functions. AWS AppConfig, a capability of AWS Systems Manager, allows customers to configure, validate, and deploy feature flags to more safely and quickly update application behavior.
