Certain embodiments enable resources assigned or allocated to an operating virtual machine (VM) to be modified while the VM is operating and without having to stop, restart, or reboot the VM. The modification may correspond to increasing or decreasing the amount of a resource being assigned to the VM. In this manner, resources assigned to a VM at the time of creation of the VM are not static and can instead be dynamically changed while the VM is operating without having to stop, reboot, or restart the VM. In some embodiments, the changes to the resources allocated to one or more VMs provided for a user (e.g., a customer) may be made according to or in response to a Service Level Agreement (SLA) entered into by the user, in response to an event such as a failover or switchover event, and the like.

Methods and systems that can launch applications into existing isolation environments do so by executing a run module on a computing machine to intercept requests to execute an application. A client communicating with the computing machine generates requests to execute an application on the computing machine. A run module identifies a profile associated with the requested application and queries an application delivery service to identify at least one isolation environment that corresponds to the profile. The run module receives from the application delivery service a response that identifies a first isolation environment associated with the application, and issues a command to a launch module to launch the application into the first isolation environment.
