Chapter 6: Implementation of Cloud Computing Services

Implementation of Storage as a Service using Google Docs.

Storage as a Service or STaaS is cloud storage that you rent from a Cloud Service Provider (CSP) and that provides basic ways to access that storage. Enterprises, small and medium businesses, home offices, and individuals can use the cloud for multimedia storage, data repositories, data backup and recovery, and disaster recovery. Some STaaS offerings can be rented based on quantity, others are rented based on a service level agreement (SLA). SLAs help establish and reinforce conditions for using data storage, such as uptime and read/write access speed. The storage you choose will typically depend on how often you intend to access the data. Cold data storage is data that you leave alone or access infrequently, whereas warm or hot data is accessed regularly and repeatedly.
