What Is Distributed Computing? Essay

The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology

In this topology, The distributed systems are connected at different sites to loosely coupled with gateway system members. The cached data between different sites is entire to the applications within each distributed system. If any system becomes unavailable, the rest of the installation to continues and

In centralized computer or minicomputer frameworks the assets like memory, stockpiling of information and system data transfer capacity ought to be managed carefully.

4. Applications where various of machines can be doled out for each to do a task e.g every processing a single file

A client/server architecture is an end-to-end systems that contains server hosts (contains the resources and services needed by the client) and clients (users or workstations in the network). “Most client/server networks have more than one client to a server so that the system shares computing power. There are a few different kinds of servers to include file sharing, printer services, email services, database services, web services, and a server can used for it power. Clients can access all of these different servers at one time and the servers can serve many clients.” (Techopedia, 2014) For large businesses with office throughout the country web based computing or cloud computing shows the greatest benefit. In web-based computing it is not the local computer doing all the work but rather computers off site that do the work. The user’s computer runs off of a cloud computing system’s interface software which uses the offsite network computers to do the work.

A distributed system is an application that executes a collection of protocols to coordinate the actions of multiple processes on a network, where all component work together to perform a single set of related tasks. A distributed system can be much larger and more powerful given the combined capabilities of the distributed components, than combinations of stand-alone systems. But it's not easy - for a distributed system to be useful, it must be reliable. This is a difficult goal to achieve because of the complexity of the interactions between simultaneously running components. A distributed system must have the following characteristics:

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

This type of computing even makes use of other resources such as SANs, network equipment, and security devices. It can also support applications that are accessible through the Internet. These applications make use of large data centers and powerful servers that host Web applications and Web services.

Cloud computing is expected to be one of the major Information Systems trends in 2009. Weinberg lists cloud computing among his Nine Hot Technologies for 2009 (2008, p. 5). He describes three levels of clouds. The first level is infrastructure in the cloud. The

You can imagine end users relying on the extended enterprise of those with the information, as a network of computers connected to the enterprise through a router or switch. All of the networked computers are going to have needs. Sometimes it requires a lot of processing power and sometimes it requires a little. Sometimes all of the networked computers will need something at once. To make the system work it is not enough to just build a system or infrastructure capable of the common tasks. There needs to be a supercomputer or nests of computers with the resources to tap into when needed. It has to be flexible to provide a lot of power to a few tasks, or some power to many tasks. The challenge is to build this infrastructure in the most efficient way possible.

Distributed computing has as of late developed as another standard for facilitating and conveying administrations over the Internet. Distributed computing is alluring to entrepreneurs as it dispenses with the requirement for clients to arrange ahead for provisioning, and permits ventures to begin from the little

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

Conventional systems were too complex to operate and maintain. Many cables were required to connect all the components, and methods to accommodate and organize the data. A single mainframe required a great deal of power, and had to be cooled to avoid overheating. Security became important and computers were expensive. Data centers were then introduced where collectively data was stored and maintained. Data collection increased rapidly over years, which led to an increase in data centers. Communication between these servers became difficult and complex. For an efficient communication between the servers many architectures were proposed. Data center architectures and requirements can differ significantly.

Multiprocessors are tightly coupled in VAXclusters and distributed systems are loosely coupled so that users could get instant results. Professionals are installing and updating programs in VAXclusters so that desired results can be obtained by users. Professionals had a goal in mind to make a system with VAX computers which will be available for users in order to process their queries with great speed and accuracy. Continued working and research gave birth to a new system which is known as VAXclusters.
