Abstract

Virtual machine storage and runtime provisioning comprises accessing a base generalized reusable virtual machine image and configuring memory according to an instantiated copy of the base virtual machine image. Project specific content is accessed from a central content store configured to store content separately from the base machine image. The instantiated machine image and project specific content are linked at launch time to form a project specific functioning virtual machine. After completion of the project specific function, the project specific content is stored separately and the project specific functioning virtual machine is removed from memory. This minimizes use of virtual machine instances to only when needed and makes content available to other users. This also minimizes proliferation of unused project specific function virtual machine images, frees-up storage space, and enables easier automated maintenance of separately stored base virtual machine images and updating of the centralized plurality of project specific contents.
