Cloud computing is an information technology (IT) paradigm, a model to allow ubiquitous access to shared pools of configurable resources (such as computer networks, servers, storage, applications and services), which can be quickly provisioned with a minimum management effort, The Internet. Cloud computing enables users and businesses with diverse computing capabilities to store and process data in a privately owned cloud or a third-party server located in a data center, making data access mechanisms more efficient and reliable. Cloud computing is based on the exchange of resources to achieve coherence and economy of scale, similar to a utility.
Advocates point out that cloud computing enables companies to avoid or minimize the initial costs of IT infrastructure. In addition, third-party clouds allow organizations to focus on their core businesses rather than spending resources on IT infrastructure and maintenance. Advocates also state that cloud computing enables enterprises to make their applications run faster, with improved manageability and less maintenance, and enables IT teams to more quickly adjust resources to meet fluctuating business demand and unpredictable. Cloud providers typically use a "pay-per-use" model. This could lead to unexpectedly high charges if administrators are not familiar with cloud pricing models.
In 2009, the availability of high-capacity networks, low-cost computers and storage devices, as well as widespread adoption of hardware virtualization, service-oriented architecture and stand-alone computing and utilities led to growth in cloud computing. Companies can increase as computing needs increase and then lower again as demand decreases. In 2013 it was reported that cloud computing had become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability and accessibility as well as availability . Some cloud vendors experience 50 percent growth rates per year, but while cloud computing is in its infancy, it has dangers that need to be addressed to make cloud computing services more reliable and easier to deploy.
