Abstract: A system comprising a processor, a profiling engine, a dependency module, and a customization module coupled to the processor for customizing a virtual machine is disclosed. Initially, the profiling engine obtains profiling data corresponding to the virtual machine. The profiling data lists active components determined to be involved in performing the function that the virtual machine is to perform. The dependency module determines dependent components utilized by the active components for implementing the functionality. The dependency module generates a dependency mapping. The dependency mapping maps the active components and the dependent components. Further, the customization module generates a list of retainable and non-retainable components. The retainable components are to be retained in the virtual machine and include the active components and dependent components. The non-retainable components are removed from the virtual machine for customizing the virtual machine.
