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.
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 came up following the evolution and adoption of extant paradigms and technologies. The objective was to enable users to benefit from the technologies and paradigms without necessarily have an understanding of or expertise of each of them. It eliminates IT obstacles and helps users to cut costs. Users are therefore able to focus on their core business instead of IT infrastructures.
Virtualization is the technology that allows for the existence of CC. A physical computing device is separated into virtual devices that are all capable of performing computer tasks. The same can happen at the operating system level, allowing for more efficient utilization of resources and time. Agility necessary for speeding up IT operations is achieved through virtualization. This reduces expenses by increasing the utilization of IT infrastructure.
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.
Various devices may be used by clients to access resources on a cloud. The only requirement is for the device to be Ethernet-enabled. Devices that can be used include smartphones, tablets, desktop computers, laptops, and home automation devices. The devices become almost useless without the cloud because they rely on it for everything. There are no specific software needed to access clouds. A browser is often enough.
Today, several deployment models exist. They include private, hybrid, community, distributed, and public clouds. Other models are multicloud and intercloud. In hybrid clouds two or more clouds are combined. Combined clouds remain distinct, but are used together.
Security and privacy are the two major concerns in this concept. Privacy and security arise from the fact that the information on clouds can be accessed at any time by the providers of the service. Additionally, service providers also share information with third parties, which may lead to loss of privacy.
