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.
Many modifications and changes have happened in the field of on-demand computing. The very origin of the term is still unknown although several proposals have been put forward. The first use of the term is however attributed to an internal document of Compaq in the year 1996. The launch of Elastic Compute Cloud by Amazon.com furthered the popularity of the concept in 2006.Since then, many companies have entered the field massively.
The concept of CC came up as a result of adopting and evolving technologies and paradigms that were in existence. With the development of CC, it became possible to make use of the paradigms and technologies without having to have expertise in them. Thus, obstacles in IT are eliminated as costs are cut. This allows users to focus on differentiating their businesses instead of laying 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.
Privacy and security are still major issues in CC. Possible infringement of privacy results from the ability of service providers to access user information. Also, sharing of information between third parties and service providers also causes potential for loss of security.
