The Future Of Cloud Computing

According to Lawrence Shawa, "a number of organizations I have spoken to have expressed concern about how secure their data is that is hosted in the cloud. There is sense of control that is taken from them making the organizations feel vulnerable" (Collection 2:1) Companies naturally feel a strong sense of obligation to protect their customers. Additionally, they may lose business if they have a reputation for compromising customer security.

The use of cloud computing creates a growing interdependence among both public and private sector entities and the individuals served by these entities. This paper provides a snapshot of the advantages of cloud computing and the risk areas specific to cloud services which clients of cloud services should be aware of. The future of cloud computing is certainly exciting, but moving more of our lives online means we will inevitably have to consider the consequences. Cloud computing means dependence on others and that could limit our privacy because

Internet outages would render all cloud business inaccessible. This would be an inconvenience to the individual user but for the corporate world an outage could be catastrophic.

Question 1. What is the most appropriate Cloud Deployment model (or combination) for BPI (Public, Private, Community, or Hybrid)?

The topic of the cloud computing industry and security is broad with far reaching intricacies. Therefore, to narrow the subject, the definition of cloud computing as defined by the National Institute of Standards and Technology (NIST) (NIST Special Publication 800-145, 2011) will be used as the foundation for this study. The NIST adopted the (Mell & Grance, 2010) cloud computing definition in 2011. (Mell & Grance, (2010)) defined cloud computing as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service-provider interaction (Mell & Grance, (2010)).

In computer networking , cloud computing is computing that involves a large number of computers connected through a communication network such as the Internet , the same as utility computing . In science , cloud computing is a synonym for distributed computing over a network, and that means the ability to run a program or application on many computers connected at the same time .

On-demand services. Cloud computing resources and services can be dispatched to users on demand. Users are able to customize and personalize computing environments, for instance, network configuration and software installation. On-demand services are able since the users have administrative privileges.

Cloud Computing is one of the most popular computing technology. It allows organizations to use resources like hardware, software and IT applications as a service through the internet or web without physically holding these resources internally. So, organization need not worry about the maintenance of these resources. These cloud applications and services can be accessed not only by PCs but also using mobile devices, such as smart phones and tablets (Dutta, Peng, & Choudhary, 2013). Furthermore, this model also provides on demand supply of resources on pay-as-you-go basis. These advantages make cloud computing more popular among other technologies.

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}.

Security is the most important thing for an organization or and company. If a company has a very big portal then we cannot say that the company is really very big but if the security of the company should be well assured that it is safe . Hence, I can say that Security is the most important hurdle for an organization to keep its data & policies undercover so that only the recommended people can have an access to it. With their business information and critical IT resources outside the firewall, customers worry about their vulnerability to attack.

It is very hard to imagine a world without computers! Everywhere you look computers are at work attempting to provide one service or another and make our lives easier. Computers, in one form or another can be found in vehicles, from cars, trucks and motorcycles to larger scale methods of transportation such as airplanes and trains. They are in your television set, your VCR, etc. But when we conjure up the image of a computer usually our first thought is of a PC, otherwise known as a personal computer. Personal computers have completely revolutionized the way the world, lives, works and conducts business. Strictly-speaking, computers arrived on the scene way back in 1936 when one Konrad Zuse produced what was then called the Z1 computer.

On-demand usage: a cloud consumer can unilaterally access the IT resources giving the user freedom to self use these resources as required. We can narrow these resources as email, network or streaming service or application which does not require human interaction.

Abstract— Cloud Computing is an approach in the field of information technology which satisfies end user requirements for computing resources like services and applications. Security of access to critical and confidential information in banks, institutions etc. are extremely essential. We can improve security of data access in cloud computing using location based encryption and authentication.

Over the years, computing concepts changing from distributed to parallel to grid to cloud computing. The evolution of computing is shown in Figure 1. Now a day, people choose cloud computing because of the advantages they get from cloud computing. The advantages are scalability, reduced management efforts, on-demand resource allocation and flexible pricing model (pay-as-you-go). Cloud computing has three service models: Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS). The basic concept of cloud computing and services is shown in Figure 2. Example of application or services using cloud computing are Microsoft OfficeLive, Dropbox, CluodNumbers, Google AppEngine, SalesForce
