gain access to computing resources. needed with little or no knowledge of where those resources are located or what the underlying technologies, hardware, operating system, etc.An environment that provides the ability to share and transparently access resources across a distributed network.
2
heterogeneous environment not only requires the technology to virtualize certain resources, but also technologies and standards in the areas of scheduling, security, accounting, systems management, and so on.
