  Citation × Citation Citation Abstract Copy Title: Innovations in Web Services Author: Patil, Rajeshwari Year: 2005 A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface that is described in a machine processable format, that systems can interact with it in a manner prescribed by its interface using messages. It is also a new innovation in the use of the Internet. Software applications written in various programming languages and running on various platforms can use the web services to exchange data over computer networks like the internet in a conceptual manner similar to inter-process communication on a single computer. This evolution of web services is ushering in new usage models; that has the potential to change the way how humans interact with computers. This paper will look at the background, provide a quick snapshot, current trends and in particular, provide analysis of how web services will change the way humans interact with computers and with it, the potential of forever changing the entire computer industry that we know of today.

  Citation × Citation Citation Abstract Copy Title: Clearing The Cloud Computing Fog Author: Banerjee, Kyle Year: 2011 Cloud computing provides libraries with a better and easier way to perform many functions. However, cloud computing is an inherently nebulous concept, so there is confusion over what it is or what what it is good for. The "Cloud" is commonly used as shorthand for Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and possibly anything that can be delivered as a service. This session provides a gentle introduction to cloud services, what they are best suited for, and topics that any institution using them should consider including confidentiality, integrity, availability, legal implications, and cost. The session will end with a demonstration of how to set up a simple web service in the Amazon Elastic Compute Cloud (EC2).

To scope and outline assumptions, a section on background research was performed and documented. The numbers from this initial research was plugged into development costs, pricing and ongoing operation expenses. Four solutions were considered: two product designs using two different development models. A conservative minimum attractive rate of return was established and applied to the models. A detailed analysis was conducted and results showed at least one viable option. Due to the limited resources and time available, many assumptions will need further investigation.

With decreasing storage and bandwidth prices, cloud computing is fast becoming the best option for cost reduction in data sharing and storage for businesses that want to reduce the cost associated with maintaining a fully staffed IT department. For companies not ready yet to take the full plunge in pure cloud computing there is the hybrid option which offers the benefits of the latter without completely switching over. Finally, there is still the on-premise option, which is available for business still learning about cloud computing and not ready yet to make changes. This paper will produce a cost reduction study based on three options, On-premise, Hybrid and Pure Cloud for SAIF corporation. The study will rely on engineering economics concepts to analyze each option and recommend the best alternative in the end.

  Citation × Citation Citation Abstract Copy Title: Content Aware Request Distribution for High Performance Web Service: A Performance Study Author: Jones, Robert M. Year: 2002 The World Wide Web is becoming a basic infrastructure for a variety of services, and the increases in audience size and client network bandwidth create service demands that are outpacing server capacity. Web clusters are one solution to this need for highperformance, highly available web server systems. We are interested in load distribution techniques, specifically Layer-7 algorithms that are content-aware. Layer- 7 algorithms allow distribution control based on the specific content requested, which is advantageous for a system that offers highly heterogenous services. We examine the performance of the Client Aware Policy (CAP) on a Linux/Apache web cluster consisting of a single web switch that directs requests to a pool of dual-processor SMP nodes. We show that the performance advantage of CAP over simple algorithms such as random and round-robin is as high as 29% on our testbed consisting of a mixture of static and dynamic content. Under heavily loaded conditions however, the performance decreases to the level of random distribution. In studying SMP vs. uniprocessor performance using the same number of processors with CAP distribution, we find that SMP dual-processor nodes under moderate workload levels provide equivalent throughput as the same number of CPU’s in a uniprocessor cluster. As workload increases to a heavily loaded state however, the SMP cluster shows reduced throughput compared to a cluster using uniprocessor nodes. We show that the web cluster’s maximum throughput increases linearly with the addition of more nodes to the server pool. We conclude that CAP is advantageous over random or round-robin distribution under certain conditions for highly dynamic workloads, and suggest some future enhancements that may improve its performance.

  Citation × Citation Citation Abstract Copy Title: Addressing Automated Adversaries of Network Applications Author: Kaiser, Edward Leo Year: 2010 The Internet supports a perpetually evolving patchwork of network services and applications. Popular applications include the World Wide Web, online commerce, online banking, email, instant messaging, multimedia streaming, and online video games. Practically all networked applications have a common objective: to directly or indirectly process requests generated by humans. Some users employ automation to establish an unfair advantage over non-automated users. The perceived and substantive damages that automated, adversarial users inflict on an application degrade its enjoyment and usability by legitimate users, and result in reputation and revenue loss for the application's service provider. This dissertation examines three challenges critical to addressing the undesirable automation of networked applications. The first challenge explores individual methods that detect various automated behaviors. Detection methods range from observing unusual network-level request traffic to sensing anomalous client operation at the application-level. Since many detection methods are not individually conclusive, the second challenge investigates how to combine detection methods to accurately identify automated adversaries. The third challenge considers how to leverage the available knowledge to disincentivize adversary automation by nullifying their advantage over legitimate users. The thesis of this dissertation is that: there exist methods to detect automated behaviors with which an application's service provider can identify and then systematically disincentivize automated adversaries. This dissertation evaluates this thesis using research performed on two network applications that have different access to the client software: Web-based services and multiplayer online games.
