Abstract: Techniques for performing load testing and profiling of services in a provider network are described. A load testing and profiling service is disclosed that analyzes profile data generated by a service and generates profile results associated with the service when the service operates at varying and/or increasing load capacities. The profile results are indicative of the performance of one or more functions performed by a service when the service operates at different load capacities. In certain embodiments, the load testing and profiling service can be invoked as part of a Continuous Deployment/Continuous Integration (CD/CI) environment that executes a load test against a test stack (e.g., test requests) before, for example, promoting code to production. For instance, the load testing and profiling service may be invoked as a step in a code deployment pipeline, e.g., for deploying a software product to a test environment, or to a production environment.
