Cloud Computing

Cloud computing is a “newsworthy” term in the IT industry in recent times and it is here to stay! Cloud computing is not a technology, or even a set of technologies – it’s an idea. Cloud computing is not a standard defined by any standards organization. Basic understanding for Cloud: “Cloud” represents the Internet; Instead of using applications installed on your computer or saving data to your hard drive, you’re working and storing stuff on the Web. Data is kept on servers and used by the service you’re using; tasks are performed in your browser using an interface/ console provided by the service. A credit card and internet access is all you need to make an investment in

The main issue that slows down the growth of cloud computing is security. No matter how many security management tools are released or assurances of reliability are made, complications with data privacy and data protection continue to plague the market. Covering all potential security issues in this article is simply impossible. This is because of the fact that we 're still discovering many of the security issues which challenges cloud computing as it is still a work-in-progress. Cloud Computing is rapidly evolving and hence what we see today may quickly become irrelevant.

Whether it’s called Cloud Computing or On-demand Computing, Software as a Service, or the Internet as Platform, the common element is a shift in the geography of computation. When you create a spreadsheet with the Google Docs service, major components of the software reside on unseen computers, whereabouts unknown, possibly scattered across continents. This affects all levels of the computational ecosystem, from casual user to software developer, IT manager, even hardware manufacturer. Recently, a lot of vendors have started talking about “cloud computing” in their marketing materials. Citing a research published by Merrill Lynch entitled “The Cloud Wars: $100+ billion at stake,” Merrill Lynch has estimated a $160- billion addressable market opportunity, including $95- billion in business and productivity applications, and another $65-billion in online advertising for Cloud Computing. But the main question is whether the users are ready to give up using services on their local machines and shift to the Cloud since shifting to cloud computing has both advantages and disadvantages for all possible users; nevertheless, they may have different level of importance for different users

Cloud computing is a popular and widely accepted paradigm built concepts such as on-demand computing resources, elastic scaling, elimination of up-front capital and operational expenses, and establishing a pay-as-you-use business model for computing and information technology services. And the adoption of virtualization, service oriented architectures, and utility computing there has been a significant development in the creation of cloud

Cloud computing is one of those buzzword that can be misleading to people unfamiliar with cloud services. With regular computing, hardware and software is part of the desktop or it is located inside an organization 's network. Cloud computing is means the hardware, storage, and software is provided as a service by another company and accessed over the Internet. The first known reference to what is today called cloud computing was in a Compaq internal document in 1996, but the term did not enter true popularity until Amazon.com introduced the Elastic Compute Cloud. There are different types and delivery models of cloud computing and at the core of Cloud Computing is that a service provider hosts the application which means they will manage software updates, handle costs of servers or development depending on how much the client pays.

So what is cloud computing exactly? There are many definition of what people thing cloud computing is but most on these have in common two

Cloud computing is an emergent computing paradigm that has the potential to make ‘computing as a utility’ a reality in the near future (Buyya et al., 2009). These days many organizations have adopted cloud computing or in the process of

With the current shift towards a more technological state within businesses and organisations, increased costs arise. These costs often relate to data management, hardware, people, as well as a multitude of other costs. Cloud computing often alleviates these costs from an organisation or business as these services are provided through a third party. [3]“It dramatically lowers the cost of entry for smaller firms trying to benefit from compute-intensive business analytics that were hither to available only to the largest of corporations”( Avram, 2014, p531). This enables more companies and businesses to meet the rising standards and information technology practices adopted by bigger and more influential companies. [3] Cloud computing and it’s cost efficiency presents an opportunity for less developed countries to benefit from the advantages that cloud computing offers without the high costs ( Avram, 2014).

Cloud Computing is a new paradigm of large-scale distributed computing which is rapidly becoming one of the hottest topic among business organisations (Pallis, 2010), and represents a fundamental change in the way of Information Technology (IT) services are invented, developed, deployed, scaled, updated, maintained and paid for (Martson et al, 2011).

In 2006 Eric Schmidt Google’s CEO used the term cloud to describe the business model of providing services across the internet. Since then cloud computing has become the most popular IT standards. It is used by various organizations to consume shared computing and storage resources in less time and reduced cost.

Cloud” computing – a latest term, Supported by ages of investigations in virtualisation, distributed, and utility

Among the most astounding features of cloud computing are that it may offer huge amounts of power with regards to computing and storage and still offer unequalled scalability and elasticity. Furthermore, when considering efficiencies and economies of scale, cloud computing services are not only cheaper, but they also provide a greener way of building and deploying IT services. However, Wang & Laszewski (2008) contend that cloud computing is distinct from other services in several ways.

Cloud is a trending term across the Internet and is often confused with data center and virtualization. To begin with, data center and virtualization are centric to the cloud, but scope of the cloud as a whole is much wider. To put in simple words, a cloud is a pool of large configurable resources that are available on demand over the Internet. These resources can be available in the form of storage devices, servers, processors, and network interfaces [4]. Packaging these resources to provide services to end-users is termed as cloud computing. The users are provided with an ease of accessibility

Cloud computing has drawn attentions from academia, industries, tech-savvy individuals and analytic firms. This positive attitude towards cloud computing resulted in numerous definitions.

“ Cloud computing does not yet have a standard definition, but a good working description of it is to say that clouds, or clusters of distributed computers, provide
