Document Summary

Comes from the early days of the internet where we drew the network as a cloud we didn"t care where the messages went, the cloud hit it from us . Second cloud around documents (www data abstraction) The emerging cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms. Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (networks, servers, storage applications),that can be rapidly provisioned and released with minimal management effort or service provider interaction. Use a provider"s applications over a network. Deploy customer created applications to a cloud. Rent processing, storage, network capacity, and other fundamental computing resources. To be considered cloud they must be deployed on top of cloud infrastructure that has the key characteristics. Sold to the public, mega scale infrastructure. Clouds are massively complex systems can be reduced to simple primitives that are replicated thousands of times and common functional units.
