Agile software development process and results

A computer program product for processing data, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising computer readable program code configured to:

• receive a command by a first version of a software component running on a first virtual machine, wherein the command is received via the first virtual machine and executed by the first version of the software component,
• pass the command from the first virtual machine to a hypervisor along with an output file comprising a functionality identifier corresponding to the command and identifiers for versions of the software component to which the command is applicable,
• transfer the command by the hypervisor to a second virtual machine for an execution of the functionality corresponding to the command by a second version of the software component if the identifier of the second version of the software component was comprised in the output file, and
• send a freeze command by the hypervisor to the second virtual machine if the identifier of the second version of the software component is not comprised in the output file.

A system, comprising:

• a memory;
• a processor communicatively coupled to the memory, the processor configured to provide resources to one or more virtual machines (VM)s;
• and
• a hypervisor, the hypervisor running on the processor, the hypervisor configured to manage execution of one or more VMs, the hypervisor executing a first VM that is running one or more software components including a first version of a software component, the hypervisor executing a second VM that is running one or more software components including a second version of the software component, the hypervisor configured to:
• send a command to the first version of the software component, wherein the command is receivable via the first VM and executable by the first version of the software component;
• receive from the first VM an output file comprising version identifiers, the version identifiers correspond to versions of the software component to which the command is applicable;
• and
• send, in response to a second version identifier not being present in the output file, a freezing command to the second VM, the freezing command causing the second VM stop running the second version of the software component.
