These days cloud computing is booming like no other technology. Every organization whether it's small, mid-sized or big, wants to adapt this cutting edge technology for its business. As cloud technology becomes immensely popular among these businesses, the question arises: Which cloud model to consider for your business? There are four types of cloud models available in the market: Public, Private, Hybrid and Community. This review paper answers the question, which model would be most beneficial for your business. All the four models are defined, discussed and compared with the benefits and pitfalls, thus giving you a clear idea, which model to adopt for your organization.

Public vs Private vs Hybrid vs Community - Cloud Computing: A Critical Review

• Builds Web instruction advice on a foundation of the latest research in how learning takes place • Translates technical Web-speak into plain English, so even nonexperts can make effective use of the Web in their teaching • Includes an accompanying Web gallery, providing examples of screen shots and links to exemplary programs • Shows instructors best practices for incorporating the Web into teaching

Web-based Instruction

Cloud computing is the biggest buzz in the computer world these days -- maybe too big of a buzz. Cloud computing means different things to different people. Cloud computing is not a small, undeveloped branch of IT. Research firm IDC thinks that cloud computing will reach $42 billion in 2012. You can do everything on cloud from running applications to storing data off-site. You can run entire operating systems on the cloud. This paper is for anyone who may have recently heard the term "cloud computing" for the first time and needs to know what it is and how it helps them.

A Comprehensive Survey on Security in Cloud Computing

Cloud computing is a set of IT services that are provided to a customer over a network on a
leased basis and with the ability to scale up or down their service requirements. Usually cloud
computing services are delivered by a third party provider who owns the infrastructure. It
advantages to mention but a few include scalability, resilience, flexibility, efficiency and
outsourcing non-core activities. Cloud computing offers an innovative business model for
organizations to adopt IT services without upfront investment. Despite the potential gains
achieved from the cloud computing, the organizations are slow in accepting it due to security
issues and challenges associated with it. Security is one of the major issues which hamper the
growth of cloud. The idea of handing over important data to another company is worrisome; such
that the consumers need to be vigilant in understanding the risks of data breaches in this new
environment. This paper introduces a detailed analysis of the cloud computing security issues
and challenges focusing on the cloud computing types and the service delivery types.

Botnets have carved a niche in contemporary networking and cybersecurity due to the impact of their operations. The botnet threat continues to evolve and adapt to countermeasures as the security landscape continues to shift. As research efforts attempt to seek a deeper and robust understanding of the nature of the threat for more effective solutions, it becomes necessary to again traverse the threat landscape, and consolidate what is known so far about botnets, that future research directions could be more easily visualised. This research uses the general exploratory approach of the qualitative methodology to survey the current botnet threat landscape: Covering the typology of botnets and their owners, the structure and lifecycle of botnets, botnet attack modes and control architectures, existing countermeasure solutions and limitations, as well as the prospects of a botnet threat. The product is a consolidation of knowledge pertaining the nature of the botnet threat; which also informs future research directions into aspects of the threat landscape where work still needs to be done.

A Botnets Circumspection: The Current Threat Landscape, and What We Know So Far

Web Services are a promising solution to an age-old need: fast and flexible information sharing among people and businesses. They represent the next phase of distributed computing, building on the shoulders of the previous distributed models. Web Services leverage the ubiquity of the Internet to link applications, systems, and resources within and among enterprises to enable exciting, new business processes and relationships with customers, partners, and suppliers around the world. They enable access to data that has previously been locked within corporate networks and accessible only by using specialized software. Along with the benefits of Web Services comes a serious risk: sensitive and private data can be exposed to people who are not supposed to see it. The security issues of Web Services in a distributed environment are a major concern of research. Web Services will never attain their tremendous potential unless we learn how to manage the associated risks. The paper therefore focuses on the general framework of security issues and the proposed solution to web services security risks.
