History of cloud computing
The word "cloud" is used to represent the internet and other communications systems. Cloud computing is the result of an evolution of the widespread adoption of virtualization, service-oriented architecture, autonomic, and utility computing in the past, telecommunications companies mainly gave simply dedicated, point-to-point data circuits to their users. Starting from the 1990's, virtual private network services was included in their contributions. It made the telecommunication companies offer equally improved services whereby cutting down on cost as well as using resources effectively.
The term "cloud" represented the computing space between the provider and the end user. In 1997, Professor Ramnath Chellapa of Emory University and the University of South California defined cloud computing as the new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone.” (Eze Castle Integration Inc., 2013)
In the late 1990s, the internal efficiencies of cloud computing and its importance was better understood by companies. In 1999, the thought of conveying enterprise-level applications to end users via the Internet was done by Salesforce.com who was the first major movers in the cloud arena. Customers with internet access were able to buy this service affordably.
In the early 2000s, Amazon.com introduced the web-based retail services .The first major organization to update its data centers was Amazon It only used 10% of their capacity due to the fact that other companies were nervous about unexpected spike in the capacity needs. The new cloud computing infrastructure model permitted Amazon to exploit their existing capacity with much grea...

...issue while in the cloud is that of security issues .You have to be careful which third party cloud service provider you dealing because all your company's sensitive information will be available to them.
Prone to Attack
Data and information stored on the cloud may become vulnerable to external hackers and threats. The internet is not completely secured lurking the likelihood of furtiveness of sensitive data.
Technical Issues
Sometimes the data and information on the cloud is not accessible anywhere due to system and technical difficulties. A very good internet connection is needed to be able to be logged on to the severs at all times. At other times there are network and connectivity issues.
Be aware of the fact that this technology is always prone to outages and other technical issues.

Today, cloud services are widely used by people around the world in purpose of business, government, and personal use. With cloud services, users use resources - could be storage, computional capability, or software- from cloud service provider mediated by Internet. Doing computational work with cloud services involves a number of computers to do the large-scale works, therefore it usually called by distributed system over Internet (reference, paper?). Cloud service also offers a large-scale service where users only pay for what they use (on-demand). Therefore, companies migrate to business-to-business cloud as they don’t have to spend money building intial cost for their computational business. For instance, instead of building their own storage, network, cooling, they could just “rent” resource from cloud provider for the lower cost. Besides money benefits, cloud resources also able to be shared by multiple...
One of the most crucial reasons one enterprise choses cloud computing is costing. Some research claimed that the cloud computing is cost-effective because it is charged on pay-as-you-go basis (Brumec and Vrcek, 2013). That means a user will pay the amount which are equal to the user’s usage. Vanmechelen et al. (2013) believes such a model will provide flexibility that ensures the user to avoid investing to excess. However, this statement fails to explain some phenomenon in reality. Set MemSQL, which is a San Francisco outfit, as an instance. When MemSQL first started up, it was based on cloud computing Amazon.com, just like what most tech enterprises in Silicon Valley did. But it gave up using Amazon cloud only two years after its foundation and returned most of its operation back to traditional computers. Eric Frenkiel, the CEO of MemSQL, announced the reason why it off the cloud was the bills from Amazon was getting bigger and bigger. “I’m not a big believer in the public cloud. It’s just not effective in the long run”, he said (Metz, 2013). The Frenkiel’s word is only able to present his own opinion. Based on what MemSQL has experienced, ...
“Google and “Amazon” were the original firms that provided cloud computing services. “Google and “Amazon’s” analysts said that cloud computing was “on-demand access to virtual information technology resources” (Budriene, Zalieckaite, 2012, p.119). The cloud is simple, it allows businesses to access IT resources over the Internet. Budriene and Zalieckaite (2012), says “Cloud computing is a new conceptual paradigm for business which combines into a single environment not only applications, architecture and business models, but a variety of professionals for performance of common business tasks in the Internet medium,” (p. 120).
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Cloud computing has captured the attention and imagination of the business and IT worlds as of late. A general atmosphere of positive analysis surrounds the potential and future of cloud computing. “In May 2008, Merrill Lynch . . . estimated the cost advantages of Cloud Computing to be three to five times for business applications and more than five times for consumer applications” (Slabeva 2010, 47). An IDC forecast suggested a near three-fold growth of spending on cloud-related services from 2008 to 2012, attaining forty-two billion dollars (Slabeva 2010). Amid all these forecasts and positive predictions, it seems obvious that the cloud is here to stay, and that those who harness it correctly will have the opportunity to grow their business, seemingly almost indefinitely.
Cloud computing is predicted to be the future technology. This paradigm is considered to be offering infinite resources and comprehensive security, due to the application of modern techniques and highly skilled personnel employed. Despite of highly skilled manpower is looking after the cloud; cybercriminals have managed to attack cloud. This work undertakes the study of threats that exist in cloud computing, the type of industries on target of cybercriminals. In addition, we have carried out the detailed study on the industries which are targeted and the method employed by the cybercriminals to target these industries. This work will be extremely helpful to researchers and enterprises to know the type of cyber attack occurring in this newly evolved paradigm and to evolve the new methods to counter them.
Cloud computing is a very ambiguous term as everyone seems to have a different definition of what it means. One definition was suggested by Simon Wardley and Connonical (2009) who believed cloud computing to be a “generic term used to describe the disruptive transformation in IT towards a service based economy driven by a set of economic, cultural and technological transformations”. As a metaphor for the Internet, "the cloud" is a familiar term, but when it is combined with the term computing, the meaning gets broader and much harder to explain. Some individuals define cloud computing as an updated version of utility computing which started up in the 1960’s while others believe cloud computing is a term that defines a much larger range of services that include Saas (software as a service), platform as a service, MSP (managed service providers) and more. Cloud computing came into the spotlight when firms started thinking about a way to increase capacity or add capabilities instantly without investing in new infrastructure, training new employees, or licensing new software. Therefore it can be argued that cloud computing includes any subscription-based or pay-per-use service that extends a firms existing IT capabilities.
Discription: Services of cloud are used by both larger and smaller scale organizations.Cloud computing has huge advantages but it is a global phenomenon therefore it has some disadvantages. Both the Service providers and the consumers must work together to ensure safety and security of data on clouds. Customers of cloud services are in fear of data loss and privacy.This paper propose to use The Cloud Security Alliance (CSA) release of a new governance, risk management, and compliance stack for cloud computing. The cloud security tools are available for free download, is meant to help organizations create public and private clouds that act accordingly with industry standards for accepted governance, risk, and compliance (GRC) best practices. The GRC stack has three components: a controls framework, a technical foundation and a questionnaire for assessing what the CSA (cloud security alliance) calls for platform-, infrastructure- and software-as-a-service

Cloud computing is sort of like the first computers come full circle – in the early days of computing, users at terminals with no computing power to speak of made use of the number-crunching capabilities of mainframes in a shared fashion – in fact, the model of computer use was called “time-sharing.” As the personal computer grew in power and capabilities while also becoming a cheap...
Cloud computing is convenient and user-friendly. It offers benefits such as the ease of software maintenance. No CD is required to install the resources and users do not have to worry if their software is out of date. Servers and capacity planning are also not required with Cloud computing. It does not require any equipment outlay and you do not need to guard against obsolete hardware. Cloud computing applications can also be access anywhere on your computer or mobile. Redundancy and disaster planning is also taken care by your cloud provider. With all these benefits cloud computing has to offer, many businesses have started to use cloud computing today. However there is also bound to have disadvantages.
Experts have claimed that the services provided by cloud computing help the companies who subscribe for its use to focus on things that would differentiate them from other in this way they don’t look for its infrastructure cost or the infrastructure of the business. Advocates likewise guarantee that this system permits undertakings to get their applications up and running
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.
One might ask how does cloud computing work? Cloud computing architecture refers to the components that work together to form cloud computing. The architecture behind cloud computing involves two different parts, the front end and the back end. Each part connects through the internet and works together. The front end structure is also referred to as the clients. This is the part or side of the server that the user interacts with and sees. For the user to connect and interact with this end, they need to have access to a computer with internet. An example of the front end structure being used is a user logging on the internet to check their email. Again, millions of people check their email every day and do not realize it is part of cloud computing. The other part of cloud computing architecture is called the back end structure. This part is responsible for the service that make the cloud work. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. () The back end service is made up of Software as a Service (SaaS), Platf...
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
