A pool of virtual environments, such as virtual machine instances and containers, can be maintained by an intermediary service, where the virtual environments can execute a specified application or service. When a request is received from a client for a connection to a resource, the intermediary service can allocate one of the virtual environments for the client and enable the client and virtual environment to communicate as if the virtual environment is executing on dedicated hardware. The virtual environment can be virtually isolated on a host machine, whereby session data for the client is stored locally in memory and then deleted at the end of the session when the virtual environment is destroyed, in order to prevent the data from being accessible between sessions and preventing multiple clients or customers from sharing the same environment over time.
