Cloud computing is a way for users to store data and operate computational processes on infrastructure connected by a network. Thus, instead of having to purchase physical infrastructure, users send processes and data out to be run and stored on infrastructure owned by other entities. The user only pays for the amount of data storage or processing capability that he or she desires. This allows the user to tap computing resources that would be impossible without owning actual, physical and vast computing resources.
By its very nature, cloud computing gives developers large tool sets for executing programs and tasks along with database storage but it also creates logistical hurdles to implementing those numerous programs, tasks and storage. For instance, developers may be required to write repetitive daemons for cloud managers and object managers to program the logistics each time an object or process is run. This equates to extra work for developers who must devote great resources on cloud logistics, separate and apart from the development of the actual end product.
