See more computer networking pictures. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs.
The word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was used to denote a network on telephony schematics. With this simplification, the implication is that the specifics of how the end points of a network are connected are not relevant for the purposes of understanding the diagram.
No one had conceived that before. The example Jim White [the designer of Telescript, X. Yet, the "data center" model where users submitted jobs to operators to run on IBM mainframes was overwhelmingly predominant. In the s, telecommunications companies, who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network VPN services How cloud computing works essay comparable quality of service, but at a lower cost.
By switching traffic as they saw fit to balance server use, they could use overall network bandwidth more effectively. Cloud computing extended this boundary to cover all servers as well as the network infrastructure. As described by Andy Hertzfeld: November Sincecloud computing has come into existence.
The OpenStack project intended to help organizations offering cloud-computing services running on standard hardware.
As an open source offering and along with other open-source solutions such as CloudStack, Ganeti and OpenNebula, it has attracted attention by several key communities.
Several studies aim at comparing these open sources offerings based on a set of criteria. On June 7,Oracle announced the Oracle Cloud. The cloud aims to cut costs, and helps the users focus on their core business instead of being impeded by IT obstacles.
Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and managed to perform computing tasks.
With operating system—level virtualization essentially creating a scalable system of multiple independent computing devices, idle computing resources can be allocated and used more efficiently. Virtualization provides the agility required to speed up IT operations, and reduces cost by increasing infrastructure utilization.
Autonomic computing automates the process through which the user can provision resources on-demand. By minimizing user involvement, automation speeds up the process, reduces labor costs and reduces the possibility of human errors.
Cloud computing adopts concepts from Service-oriented Architecture SOA that can help the user break these problems into services that can be integrated to provide a solution. Cloud computing provides all of its resources as services, and makes use of the well-established standards and best practices gained in the domain of SOA to allow global and easy access to cloud services in a standardized way.
Cloud computing also leverages concepts from utility computing to provide metrics for the services used. Such metrics are at the core of the public cloud pay-per-use models. In addition, measured services are an essential part of the feedback loop in autonomic computing, allowing services to scale on-demand and to perform automatic failure recovery.
Cloud computing is a kind of grid computing ; it has evolved by addressing the QoS quality of service and reliability problems.
Client—server model —Client—server computing refers broadly to any distributed application that distinguishes between service providers servers and service requestors clients. Furthermore, fog computing handles data at the network level, on smart devices and on the end-user client side e.
Mainframe computer —Powerful computers used mainly by large organizations for critical applications, typically bulk data processing such as: Utility computing —The "packaging of computing resourcessuch as computation and storage, as a metered service similar to a traditional public utility, such as electricity.
Participants are both suppliers and consumers of resources in contrast to the traditional client—server model. Cloud sandbox —A live, isolated computer environment in which a program, code or file can run without affecting the application in which it runs.
Characteristics Cloud computing exhibits the following key characteristics: Cost reductions are claimed by cloud providers. A public-cloud delivery model converts capital expenditures e.
Pricing on a utility computing basis is "fine-grained", with usage-based billing options. As well, less in-house IT skills are required for implementation of projects that use cloud computing.
Device and location independence  enable users to access systems using a web browser regardless of their location or what device they use e. As infrastructure is off-site typically provided by a third-party and accessed via the Internet, users can connect to it from anywhere. Multitenancy enables sharing of resources and costs across a large pool of users thus allowing for: There is a sense of location independence in that the consumer generally have no control or knowledge over the exact location of the provided resource.
Time may be saved as information does not need to be re-entered when fields are matched, nor do users need to install application software upgrades to their computer. Security is often as good as or better than other traditional systems, in part because service providers are able to devote resources to solving security issues that many customers cannot afford to tackle or which they lack the technical skills to address.
In addition, user access to security audit logs may be difficult or impossible.The cloud isn't magic; it is actually a actual shipping system using a construction which makes the whole thing work. Cloud computing is characterized from the Investopedia online dictionary for a tool for delivering data and software stored in servers which is retrieved on the net through web-based instruments and software, as opposed to a direct connection to a server.
How Cloud Computing Works Essay - At first glance “The Cloud” appears to be magical but like a visit to “The Great and Powerful OZ’ when you look deeper you find that there is more to it behind the curtain.
In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. Private cloud computing works in much the same way but you access the resources you use through secure network connections, much like an Intranet.
Companies such as Amazon also let you use their publicly accessible cloud to make your own secure private cloud, known as a Virtual Private Cloud (VPC), using virtual private network (VPN) connections.
Cloud Computing Software Essay Words | 7 Pages. topic of Cloud computing, Cloud computing software to be exact.
For the purpose of this report information was gathered from various sources including electronic data, books, online journals and the World Wide Web. The only thing the user's computer needs to be able to run is the cloud computing system's interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest.
There's a good chance you've already used some form of cloud computing.
