Techniques for operating web services within secure execution environments running within computing resource service provider environments are described herein. A web service provides an application that can be instantiated within a secure execution environment associated with a customer computer system that is hosted by a computing resource service provider and programmatically managed by the customer and the customer computer system provides validation of the secure execution environment. Web service requests from the customer computer system are received by the web service application hosted within the secure execution environment. As the one or more web service requests are received by the web service within the secure execution environment, the requests are fulfilled by executing instructions associated with the web service within the secure execution environment.
