Cloud computing is an information technology (IT) paradigm that enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility.
Cloud Computing also known as the Cloud, centers on maximizing the efficiency and the organization of shared resources. With cloud computing, one can not only share and organize the data between multiple users, but also dynamically reallocate data per business demand, or synchronously. This specific approach of data storage and management reduces the cost by not needing to buy physical computer servers to store the data, the storage space, electricity and similar expenses.
Cloud storage, unlike physical data storage provide users and employees to access the data and database from remote location, and update the data relatively easily. A lot of users can use this to work simultaneously, while being in separate location, and efficiently.
Among multitude of advantages of cloud computing, here are a few:
• Agility improves with users’ ability to re-provision technological infrastructure resources.
• Application programming interface (API) accessibility to software that enables machines to interact with cloud software in the same way that a traditional user do.
• Cost reductions claimed by cloud providers. A public-cloud delivery model converts capital expenditure to operational expenditure.
• Maintenance of cloud computing applications is easier, because they do not need to be installed on each user’s computer and can be accessed from different places.
• Multi-tenancy enables sharing of resources and costs across a large pool of users.
• Time saved as information does not need to be re-entered when fields are matched, nor do users need to install application software upgrades to their computer.
• Reliability improves with the use of multiple redundant sites, which makes well-designed cloud computing suitable for business continuity and disaster recovery.
