The Revolution Of Cloud Computing

Reordering the economics of software, cloud computing is alleviating many of the capital expenses (CAPEX), inflexibility of previous-generation software platforms, and inability of on-premise applications to be customized on an ongoing basis to evolving customer needs. These are the three top factors of many that are driving the adoption of cloud computing technologies in enterprises today. Implicit in the entire series of critical success factors that are forcing the migration of on-premise to cloud computing platforms is the greater agility and speed the latter platform offers. Line-of-business executives today are increasingly defining the priorities of IT departments, often also defining budgeting cycles as well. Their primary concern is ability able to quickly get up and running on a new enterprise application, integrating its workflows into existing legacy and 3rd party systems, databases and applications, while also getting the performance gains of the new software (Bentley, 2008). Due to these factors cloud computing is evolving rapidly, changing the economics of enterprise software especially. Large-scale systems are most often purchased using Capital Expense (CAPEX) budgeting processes that often take several months ot over a year to complete. Often CAPEX-based spending on enterprise software also requires the board of directors for a company to authorize spending large amounts on new

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.

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

The contents of this report will include the history of Cloud computing, the main trends within Cloud computing, the advantages and disadvantages of Cloud computing and the future of Cloud computing.

The current scenario in cloud computing has evolved from traditional need of cloud platforms as a single platform of data storage and virtual machines to Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Due to growth in availability of number of cloud providers in the market, providers are facing intense pressure of competition for providing best prices and complement it with the best Quality of Service(QoS). QoS is dependent on various factors like latency, acceptance rate as well as reliability. Cloud providers must meet all these requirements and keeping the running costs as low as possible. The pattern of access to these services varies depending on the time of access.

In 2008, the economist published a little supplement that went out with their magazine, that started to introduce with a concept of something called cloud computing. They put this quote up as part of that “The rise of the cloud will transform the Information Technology (IT) industry, but it will also profoundly change the way people work and companies operate” (The Economist, Oct 2008). Now 8 years later, the above quote is still relevant when we talk about cloud computing and what a cloud can do. The reason why it is important to still use this quote is that this is presence but we don’t yet appreciate quite how disruptive or transformative cloud computing is going to be for companies, individuals and for society. If we consider

In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control [6], [7] is paramount as it is the first line of defense that prevents unauthorized access to the shared data. With the burgeoning of network technology and mobile terminal, online data sharing has become a new “pet”, such as Facebook, MySpace, and Badoo. Meanwhile, cloud is one of the most promising application platforms to solve the explosive expanding of data sharing. In cloud computing, to protect data from leaking, users need to encrypt their data before being shared. Access control is paramount that prevents unauthorized access to the shared data. Recently, attribute-based encryption (ABE) has been attracted

: Cloud computing is the well-known model used for storing huge amount of data over the internet and provides the convenient mechanisms to access the information. Since it is keeping up enormous measures of assets, its protection and security are the major issues. The cloud administration suppliers are not trusted and unethical, so information is to be secured. Still, some information might be accessible that the data proprietor does not wish for progress data to the cloud unless query confidentiality and data privacy are assured. On the other hand, protected query processing services have to grant efficient query processing and drastically reduce the internal workload to fully understand the benefits. “Random space perturbation (RASP) processing” method provides security and various query processing services to provide confidentiality in the cloud. The (K-Nearest Neighbour) KNN-R algorithm is used here to convert the range query to the KNN query. Users have been certified by using the randomly generated key value provided by the administrator subsequent to successful registration by the client thus maintaining privacy. Queries from users are retrieved within the least period of time i.e., less than a second. In future using RASP statistics and KNN queries to investigate supplementary applications of RASP perturbation for protected data concentrated computing in the cloud.

The cloud is a network of servers, each with a different function. In the last five years, the cloud has introduced new ways of managing data; however it has made leaps and strides since it was first thought of. The idea of cloud computing stems from many people, however, Professor John McCarthy of MIT and Dr. J.C.R. Licklider are given credit for developing the concept. The history of the cloud dates back to the1950s. Back then, high-performance computers called mainframes were used. Mainframes were very large computers that took up entire rooms. Mainframe computers were also expensive. Because of this, organizations could not afford to purchase a new mainframe for each individual in their company. As a response, “time sharing” methods

Cloud computing is a topic of which much is assumed. The average person recognizes the term “cloud computing” as having to do with their storage from their iPad or iPhone on the online storage area which syncs their Apple devices to their computer. This common cloud is called the iCloud. That is where common knowledge ends about this topic. However, upon further exploration, a deeper understanding is gained with greater explanation, and it is realized that cloud computing is something that is used all of the time on many levels of everyday technology. While the terminology remains cryptic to the mind of most people, the concepts behind the practical uses of cloud computing become quite clear. It is relatable and understandable. Upon this revelation, the iCloud is recognized as the tip of the preverbal iceberg when speaking about cloud computing. It is important to discuss and further understand the many types of cloud computing as well as the various applications to life through technology. This affects how information is stored online, computers are protected, information is secured, emails are processed, and many other factors that are taken for granted in the world of technology. Cloud computing is a general term used to describe how information is stored, utilized, and accessed over the internet. There is no cloud, but the word cloud gives the connotation of an abstract place which is known to exist but is too vast to touch or contain (Griffith,

Cloud computing has become the most common phenomenon in the recent years. More and more cloud services have flourished all around the world such as computing resource, storage space outsourcing and different kinds of software applications. For many reasons like low cost, efficiency, convenience, better connectivity and etc., user often stores his data on remote servers. Since more servers are public, there exist a lot of risks for the data in the transition process, the user ensures the privacy of his data by storing it in encrypted form, then he can search the encrypted data and retrieve it. The first effort of searching encrypted data by keyword was tackled by Song, Wagner and Perrig cite{s1}. To securely search over encrypted data, searchable encryption schemes have been proposed in recent years cite{b2,b3,b5,c2,c4,g1,w2}, which can be divided into two schemes: symmetric searchable encryption (SSE) and asymmetric searchable encryption (ASE). To perform a search on a dataset, an user creates an index of keywords listed in the documents and later on executes the search on the index in a way that allows the server to retrieve the documents contain a certain keyword instead of retrieving all the encrypted documents back which is fully impractical solution in cloud computing scenarios. Recent refinements and extensions to this scheme are given in cite{g1, w2}.

The trend of utilizing cloud computing technology in education is on the rise. However, with most technical applications there are always limitations, opportunities, and special considerations. Each of these will be examined in further detail below.

Popularity of cloud computing has made many of our lives easier. As the popularity of this technology is growing so are the demands from the consumers of the technology. This has lead to inter-cloud operations. Interoperability of clouds is facing many obstacles and need for standardization of specifications. Though there are a couple of standard specifications none have been widely accepted. This report has made an effort to show the possibility of using next generation overlay networks (NGSON) for an efficient interoperability of clouds, keeping the standardized specifications given by the IEEE SA.

During the course of this class, I believe that my positive attitude towards difficult situations has helped me overcome many problems. When I started my individual topics, I reviewed several similar projects from last year. After reading their reports, I gained deep understanding about the Cloud computing, but I was getting worried about what are some new materials I should include in my slices and my final report. I didn’t give up or get frustrated. Instead, I start doing research step by step.
