Decision Support Tools for Cloud Migration in the Enterprise

This paper describes two tools that aim to support decision making during the migration of IT systems to the cloud. The first is a modeling tool that produces cost estimates of using public IaaS clouds. The tool enables IT architects to model their applications, data and infrastructure requirements in addition to their computational resource usage patterns. The tool can be used to compare the cost of different cloud providers, deployment options and usage scenarios. The second tool is a spreadsheet that outlines the benefits and risks of using IaaS clouds from an enterprise perspective; this tool provides a starting point for risk assessment. Two case studies were used to evaluate the tools. The tools were useful as they informed decision makers about the costs, benefits and risks of using the cloud.Comment: To appear in IEEE CLOUD 201

Enabling Interoperability For Autonomous Digital Libraries : An API To CiteSeer Services

We introduce CiteSeer-API, a public API to CiteSeer-like services. CiteSeer-API is SOAP/WSDL based and allows for easy programatical access to all the specific functionalities offered by CiteSeer services, including full text search of documents and citations and citation-based document discovery. CiteSeer-API is currently showcased on SMEALSearch [10], a digital library search engine for business academic publications
