Which statement describes a characteristic of cloud computing?
Cloud computing is the availability of computer system resources on demand, especially in data collection and computing power, without the active direct management of the user. This term is usually used to describe data centers available to many users on the Internet. Great clouds, today's major, are often distributed tasks on multiple sites by central servers. If the user's connection is relatively close, then it can be named as an edge server.
Clouds may be limited to a single organization (corporate cloud [1] [2]), may be available for combination of multiple organizations (public cloud) or both (Hybrid Cloud).

The cloud computing is based on the sharing of resources to achieve sustainability and economies of scale.
Advocates of public and hybrid clouds have noticed that cloud computing allows companies to avoid or minimize the initial costs of IT infrastructure. Supporters also claim that cloud computing allows companies to run their applications faster, with better management and less maintenance, and to make it faster for resources to meet the ups and downs of IT teams Allows to adjust [2] [3] [4] Cloud service providers typically use the "pay-as-you-go" model, which may cause unexpected operating costs if administrators are not familiar with pricing models. [5]

Cloud computing has increased due to the availability of high capacity networks, low-cost computers and storage devices, as well as extensive virtualization of hardware virtualization, service-oriented architecture and autonomous computing and utilities.

"Cloud computing" was popularized with Amazon.com, which released its elastic compute cloud product in 2006, [9] the phrase "cloud computing" has appeared in the beginning of 1996, the first mention was made in a document. Was the Interior Compaq [10]

The cloud symbol was used in the original ARPANET to represent the IT device network in 1977 [11] and in 1981 as CSNET [12] - both of the predecessors of the Internet. The term cloud was used as an Internet metaphor, and a standardized cloud-like look was used to pinpoint the network on telephone plans. With this simplification, the implication is that how the end points of a network are connected, its specifications are not relevant to the understanding of the diagram. [Citation needed]

Cloud cloud was used to refer to distributed computing platforms in 1993, when Spin-off Apple General Magic and AT & T used it to describe their (coupled) telecropy and personalized technologies. [13] In Wired film, In April 1994, "Bill and Endes Excellent Adventure II", Andy Hertzfeld commented on the distributed programming language of Telescript, General Magic:

"The beauty of the telecope ... is that, instead of just programming one device, we now have the entire cloud, where a single program can go and many different sources of information can travel and one can The type of virtual service can not be used before, no one even imagined it. Example of Jim White [Telescript, X.400 and Designer of ASN.1] Now is a date organization service where a software A Ent is a flower shop and order. Tend to flower and then the ticket office and get tickets for the show, and everything is communicated to both parties.

During the 1960s, the concept of initial time-sharing became popular through RJE (Remote Job Entry); [15] This term was mainly associated with big sellers such as IBM and DEC. In the early 1970s, full-time sharing solutions were available on platforms such as Multisticks (on GE hardware), Cambridge CTSS and earlier Unix port (on DEC hardware). However, the "data center" model in which users sent jobs to operators for execution on IBM mainframe, was very important.
In the 1990s, telecom companies, which previously offered dedicated point-to-point data circuits, started offering virtual private networks (VPN) services with comparable quality of service, but at a lower cost . By balancing the use of the server properly, they can use the overall network bandwidth more effectively. [Citation needed] They began using the cloud symbol to point out the demarcation point between responsible providers and responsible users. Cloud computing has increased this limit to cover all servers and network infrastructure. [16] As computers spread, scientists and technologists have discovered time to share ways to provide computing power to large numbers of users by sharing time. [Citation needed] They experimented with algorithms to prioritize the CPU and optimize the infrastructure, platform and applications to increase efficiency for end users. [17]

Cloud metaphor for virtualized services is used for at least General Magic in 1994, in which it was used to describe the universe of "places", in which the mobile agent could go in the telecit environment. As described by Andy Hartzfeld:

Andy says, "The beauty of the telece script," is that instead of just programming one device, we now have whole cloud out, where a single program can go and travel to many different sources of information. One could make and order a virtual service. [1.]

The use of cloud metaphor is credited to General Magic Communications worker David Hoffman on the basis of long-term use in networking and telecommunications. In addition to being used by General Magic, it has also been used to promote services related to AT & T. [19]

The aim of cloud computing is to allow users to take advantage of all these techniques without the need of deep knowledge or experience with each of them. The purpose of the cloud is to reduce costs and help users focus on their core business rather than being interrupted by IT barriers. [39] The main competent technology for cloud computing is Virtualization. Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and can be used to perform calculation tasks. With the operating system-level virtualization that essentially creates a scalable system of many independent computing devices, passive computing resources can be allocated and can be used more efficiently. Virtualization provides the necessary agility to speed up IT operations and reduce cost by increasing the use of infrastructure. Autonomous computing automates the process by which the user can provide resources on demand. By reducing user participation, accelerating automation process, reducing labor costs and reducing the possibility of human error. [39]

Users regularly face difficult business problems. Cloud computing adopts the concepts of service-oriented architecture (SOA) that can help the user to split these problems into services that can be integrated to provide solutions. Provides all its resources as cloud computing services and uses standards and best practices gained in SOA domains that allow global and easy access to cloud services in a standardized manner.

Cloud computing also leverages utility computing concepts to provide metrics for the services used. These parameters are in the heart of the public cloud pay-per-use model. In addition, measured services are an essential part of the reaction cycle in autonomous processing, allowing services to scale on demand and automatic error retrieval. Cloud computing is a kind of grid computing; It has evolved by facing the problems of QoS (quality of service) and reliability problems. Cloud computing provides tools and technologies to build intensive parallel data/processing applications with much more affordable prices than traditional parallel computing technologies.
