...iOS” The competition between Google Android and Apple iOSis one of the most talked after wars in mobile gadget platforms. The Google Android platform is increasingly becoming dominant in the smartphones and tablets market. Nokia, a once leading company in the mobile phone market is slowly entering the smartphone market with a new range of Lumia smartphones powered by Windows 8 mobile as it phases out its range of Symbian powered smartphones. Equally, Motorola Mobility is trying to gain a share of the market by increasing its product portfolio of smartphones in the Droid family. The Android Operating System powers the Droid range of smartphones. Samsung is by far the largest mobile manufacturing company in the world with a full range of Android powered smartphones in the Galaxy family. The recent entry of the Samsung Galaxy SIII heightened the competitive advantage of the Android Software Platform based on the Android 4.0 (Ice Cream Sandwich) software.

...CLOUD COMPUTING NAME: INSTITUTION: Question 1. What is the most appropriate Cloud Deployment model (or combination) for BPI (Public, Private, Community, or Hybrid)? One of the main things that we need to understand in the process of selecting the appropriate cloud development model for BPI is to understand what cloud deployment is all about. Cloud has been used for a while now and as business and security comes, it is predicted to be rising faster as years come by. The ubiquitous term cloud refers to anything that is being delivered today through the internet and in simple terms, cloud is where one can rent technology and information services on the internet through the providers. Most companies are today turning their focus on leveraging the cloud so as to cut down their capital expenditure and this is the same case with BPI which is looking for a better way to control its operating cost, therefore there is a high need for BPI to seek cloud adoption. It is vital to understand that cloud sometimes come with security risks for the IT department, which can turn out to be severely expensive for BPI to deal with, based on the current financial stress that the company is experiencing. Therefore, it is very vital for BPI to understand its requirements as it opts to a deployment model that is available on cloud. There are four different types of deployment models and these are: the private cloud, the public cloud, the hybrid cloud and the community cloud. BPI is a multinational company...

...Cloud Computing Praveen Reddy, Polam Wilmington University SEC-6040 1. Introduction Cloud computing is the term that describes about the computer related services through the internet. As technology developments are increased significantly, many individuals and businesses are interested to use software and hardware services that are managed by third parties at remote locations (Mirzaei, 2008). The term “ cloud “ can be truly understandable how the cloud can be a value to an organization by providing various services like online data storage, social networking, online business applications and webmail’s etc. because, the cloud computing allows access to information and computer related resources from any location that has network connection (Mirzaei, 2008). 2. Components of Cloud Computing: 2.1 Cloud Client: Clients play a key role in providing access for users to client devices which consists of computer software and hardware that depends on cloud computing for application delivery. And also there are several applications which are designed specifically for delivery of cloud services and it is essentially useless without the application. For example which can include devices like computers, mobile phones and applications like operating systems, browsers etc (Nichols, 2011). The cloud client has three different types, they are * Mobile clients. * Thick clients (Nichols, 2011). * Thin clients (Most popular) (Nichols, 2011). 2.2 Distributed Servers:...

...Sharing: Distributed system users has the ability to use any component (hardware, software or piece of data) anywhere in the system. The access to the system is being controlled by suitable resource manager that provides naming scheme and controls concurrency depending on sharing models describing how resources are provided, used and interact with each other. • Openness: It has to do with the system ability of the system components to publish their interfaces in details, intergrade with new components and function efficiently on a variety of processors. • Concurrency: Distributed systems components processes are running concurrently depending on suitable coordination mechanisms • Scalability: The ability to serve more users preserving or increasing its performance levels. • Fault Tolerance: The system has to be available even if one or more components fail. • Transparency: All kind of system users perceives it as a simple one rather than a set of components working on the same goal. Distributed systems definition and characteristics emerge three main elements that are shared by their users: • Resources: Resource sharing is the state that available hardware and software is accessible from system’s users. User access is controlled by suitable modules called resource managers. The scope of these modules is to efficiently assign resources to users. Resources managers use a system model to describe resources and a scheduler to control desired allocations. System model provides real time...

...Proceedings of the 44th Hawaii International Conference on System Sciences - 2011 Cloud Hooks: Security and Privacy Issues in Cloud Computing Wayne A. Jansen, NIST Abstract In meteorology, the most destructive extratropical cyclones evolve with the formation of a bent-back front and cloud head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses. • applications can be developed upon and deployed. It can reduce the cost and complexity of buying, housing, and managing hardware and software components of the platform. Infrastructure-as-a-Service (IaaS) enables a software deployment model in which the basic computing infrastructure of servers, software, and network equipment is provided as an on-demand service upon which a platform to develop and execute applications can be founded.

...The easiest way for them to gain access to the confidential data on the network is by bluffing a person , making him to handover the secret keys and it is not just by writing a clever piece of code. The phishing attacks are increasing these days, as fake official messages and websites, or communications would appear just like coming from the trusted sources on the network. The hackers are trained experts who will gain access to the destination servers. Most of the time hackers target very high level executives in order to steal and utilize their data for various malicious activities on the network. If the data is related to CEO of an XYZ company, it can be easily hacked, whereas it is still easier to hack data related to other people on the network. In order to avoid these types of attacks we need a security product which is capable of performing real-time monitoring of malicious data with the feature of preventive blocking capabilities of these malicious traffic on the...

...Cloud Computing: Moving Riordan into the Future Sean Mahany, Claude Bartee, and Michael Robles CIS/207 3/12/2014 Vikram Chowdiah Cloud Computing In essence cloud computing is what most companies today use, it is the way of the future. It will allow all of Riordan’s manufacturing facilities to work more cohesively and share services via a web server. Cloud computing will also allow Riordan to get all of their applications up and running faster and more smoothly. It will also reduce the environmental damage due to the decrease of power cloud computing requires. The unpredictable and sometimes fluctuating business demand will enable the IT department of Riordan to rapidly adjust resources. The system will improve the ability to manage the cloud computing services more easily. Although companies that provide the cloud service usually use a “pay as you go model” which in turn can have unexpectedly high and increasing charges if the administrators do not adapt to the prices of using the Cloud services. With the service, multiple users can access and edit their data without having to pay for licenses for certain applications they normally would have to use without the Cloud service. The implantation of the service requires less IT trained employees, so that would decrease the amount of training Riordan would have to spend to train their employees in IT. The maintenance aspect is easier due to the fact the service does not need to be installed on each user’s computers...
