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 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.
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.
There are three main service models in CC. These services advocate for making everything a service that can be used only when needed in a similar manner to how service providers render their services to those who need them. The three models of services are infrastructures as a service (IaaS), Platform and a service (PaaS), and Software as a service (SaaS). IaaS abstracts users from the details involved in infrastructure such as location, data partitioning, physical computer resources, security, backup, and scaling.
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.
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.
