Amazon Elastic Compute Cloud (Amazon EC2) instances run the IBM WebSphere Commerce Suite that enables customers to shop on an ABOF website compatible with fixed or mobile devices, or using an ABOF mobile application.

Technology changes in 2010 made way for new opportunities and competition for eLoanDocs. Technology vendors like Amazon began to offer cloud computing. Cloud computing is a non-platform dependency network of virtualization, service-oriented architecture, grid computing, and utility computing that allows manipulating, configuring, and accessing applications online (Cain et al., p. 765). There is no evidence of trail to the host server.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

Once the internet became a viable medium for cloud-based computing, companies started offering applications to the masses. In early 2000’s, Amazon developed a cloud-based tool, Amazon Mechanical Turk, which offered cloud computing, data storage and artificial intelligence. Later, in 2006, Amazon released its second generation cloud services known as Elastic Compute Cloud (EC2) that allowed individuals and organizations to rent computing space to run all their computer applications and data storage needs. With EC2, Amazon had truly brought in to the concept of cloud computing. After that computer giants like Google, Microsoft and Apple began to offer affordable, useful applications for computers and smart devices that were able to on the cloud and not by the devises. Consequently, there are tens of thousands of such cloud-based applications available.

Cloud computing is revolutionizing the use software globally at a very rapid pace as it is completely redefining the economics of how software is purchased and used. Web 2.0 technologies and their underlying design precepts are responsible for the current and future generations of social networks (Bernoff, Li, 2008). Both have immediate and significant impacts on the operations of businesses and the major contributions each makes are explained in this analysis.

As today, IT world is heavily based on cloud computing and most of the companies had earned billions through this technology like Google, Salesforce and Amazon. As Amazon is considered the top E-commerce company of the world so customers expect 24*7 services from them. Even the server drop of single minute

Salesforce.com allows companies to eliminate the hardware and software needed for their internal network instead salesforce.com takes that responsibility. Companies only pay for what they need, upgrades are automatic and they can increase or decrease their services easily. Salesforce.com paved the way for both specialist and mainstream software firms to deliver applications over the internet. The next development in cloud computing was Amazon Web Services in 2002, which provided a suite of cloud-based services including storage, computation and human intelligence through the Amazon Mechanical Turk. Amazon Mechanical Turk holds a database of human intelligence tasks these are tasks that people can login to complete for money or credit. These tasks can range from organizing photos to debugging software. These are all task that can only be performed by people and not computers. In 2006, Amazon launched its Elastic Compute cloud (EC2) as a commercial web service that allows small companies and individuals to rent computers on which to run their own computer applications. Amazon EC2 presented a virtual computing environment, allowing companies to use web service instances with a variety of operating systems, they can load them with custom applications, manage their network’s access permissions, and run their service using as many or few systems as they desired. In 2009, Web 2.0 hit its stride, Google and others started to offer browser-based

Cloud computing facilities not only massive cost savings but also helps to increase the business continuity and agility. It is essential for SMEs to adopt this innovative technology due to the current economic constraints (Mell and Grance, 2009; Aljabre, 2012; Sultan, 2011). To adopt cloud they have the latest technology at hand which provide necessary tools to compete over the rivals and gain the competitive edge. SMEs staff can perform more innovative business operations rather not thinking much about the technical complexity.

AMAZON AUTO-SCALING: Amazon Web Services gives a mechanism named as Auto-Scaling with a part of EC2 service. The reactive approach is used by AAS. Auto-Scaling Group decided to add/delete a number of VM's. Amazon also offers EMR ( Elastic MapReduce) which provides fully managed hosted Hadoop framework over EC2.

This innovation and low cost associated with AWS lets small and large companies launch their offerings at faster rates and lower costs. AWS also lets you scale up applications to accelerate performance.

Cloud computing involves a lot of concepts and technologies. Companies and corporations such as Amazon, Google and Microsoft are providing services following the logic of computational infrastructure cloud computing, with Amazon the pioneer in providing and marketing infrastructure of this kind.

The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centres all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centres are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Google Apps is a great example of cloud computing as companies to no longer require the need for installed word processing software, in house email servers, multiple IT personnel and many more cost saving advantages. Google Apps allows companies to access all services including email, website hosting, calendar, document editing/creation and much more directly through a web browser. The advantage to using Google Apps is increased productivity, security, lower IT costs and data backup. Microsoft has also entered the cloud computing realm by integrating its current software such as Word and outlook with online storage and easy accessibility.

Cloud as the term signifies means the computers in a network to be used for data storage remotely and for maintenance. The cloud computing offers reductions in costs and also has increased scalability, reliability and flexibility in its own processes, and is considered as todays one of the most exciting technologies and has seen a rapid growth over the past ten years. The Cloud computing uses advanced level of computational
