Cloud computing refers to a model in computing that enables universal, convenient, on-demand access and sharing of computer resources. It allows for access to computer resources by users and other computers when there is need to minimize wastage and allow universal access. The name on-demand computing is often used to refer to this concept too. With this concept, economies of scale and coherence can be achieved in computer networks. When one needs to understand more concerning cloud computing Columbus OH offers a great place to visit.
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.
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.
