Cloud computing (CC) is a model that allows ubiquitous, convenient, and on-demand access to computing resources. Other computers and users only access resources when they need them, which minimizes wastage and allows universal use of similar resources. Another name used to refer to this concept is on-demand computing, owing to its nature. It allows for the achievement of coherence and economies of scale in computer networks. When in need of understanding more about cloud computing Columbus OH is the place to visit.
On-demand computing has seen a lot of change happen to it. Where the name originated is still unclear although several suggestions have been presented to explain its origin. However, Compaq is credited with using the term for the first time in 1996 in an internal document. Amazon.com later made the concept more popular with the launch of the Elastic Compute Cloud.
CC developed from the adoption and evolution of paradigms and technologies in existence. The objective of its development is to allow the utilization of the various paradigms and technologies without having to understand or possess expertise in them. It allows for cutting of costs and elimination of IT obstacles. Therefore, users can focus more on differentiating their businesses from others instead of IT infrastructures.
The existence of CC springs from a technology known as virtualization. Through virtualization, physical computing devices are separated into virtual gadgets, each with the capability of performing tasks. The same level of virtualization can be done at the operating system level to allow for more efficient use of time and resources. Virtualizations helps in the achievement of the necessary speed needed to fasten IT operations. Thus, expenses are cut as utilization of IT infrastructure is increased.
So far, there exists three key service models available in CC. With these service models, everything is transformed into a service only to be hired when needed. The three models of service include Software as a service (SaaS), Platform and a service (PaaS), and infrastructures as a service (IaaS. Through IaaS, all details that are entailed in physical infrastructure are abstracted to users. Some of the abstracted details include physical computer resources, location, data partitioning, backup, scaling, and security.
Resources on a cloud can be accessed by clients using various devices. The device needs to be Ethernet enabled and it can be a smartphone, tablet, desktop computer, laptop, or home automation gadgets. The gadgets rely on the cloud for all or most of their applications without which they would be useless. A web browser is required for accessing resources on clouds. No other specific software is necessary.
There are a few deployment models in use today. These include private, public, hybrid, community, and distributed clouds. Others include multicloud and intercloud. Hybrid clouds combine two or more clouds such as private and community or public and private. Individual clouds remain distinct, but are used together.
The major concerns in CC are security and privacy. The ability of service providers to access user information is one of the major sources of privacy issues. Security issues result from sharing of user information between service providers and third parties.
