The concept of universal, convenient, on-demand sharing and access of computer resources which is slowly taking over in the digital world is called Cloud Computing (CC). Under this concept, wastage is computer resources is minimized while allowing for universal access as users only access resources when they need them. Another term used for the concept is on-demand computing. Coherence and economies of scale in computer networks are achieved with this concept. To better understand the concept of cloud computing Columbus OH is a nice place to go.
The concept of on-demand computing has undergone a lot of changes. The exact origin of the term is still unclear up to this day even though several theories have been forwarded by various theorists regarding its origin. However, the use of the term goes as back 1996, with Compaq using it in one of its internal documents. Real popularization occurred in 2006 with the introduction of the Elastic Compute Cloud by Amazon.com.
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 entire existence of CC is based on a technology called virtualization. Virtualization allows for separation of physical computing devices into virtual gadgets that are capable of doing tasks. Virtualization at the operating system level allows resources and time to be used more efficiently. IT operations are sped up through virtualization because it provides the needed speed. With increased speed, utilization of infrastructure is increase, which cuts costs.
So far, CC has three major service models in existence. These models exist to make everything a service that can be hired from service providers when needed and then returned when not needed. These models are infrastructures as a service (IaaS), Software as a service (SaaS), and Platform and a service (PaaS). Through IaaS, the details entailed in infrastructure are abstracted to the user. Infrastructure details abstracted include location, physical computer resources, data partitioning, backup, security, and scaling.
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.
