—Virtualization has become a popular way to make more efficient use of server resources within both private data centers and public cloud platforms. While recent advances in CPU architectures and new virtualization techniques have reduced the performance cost of using virtualization, overheads still exist, particularly when multiple virtual machines are(More)
It is commonly agreed that accounts receivable (AR) can be a source of financial difficulty for firms when they are not efficiently managed and are underperforming. Experience across multiple industries shows that effective management of AR and overall financial performance of firms are positively correlated. In this paper we address the problem of reducing(More)
—Cloud data centers are difficult to manage because providers have no knowledge of what applications are being run by customers or how they interact. As a consequence, current clouds provide minimal automated management func-tionality, passing the problem on to users who have access to even fewer tools since they lack insight into the underlying(More)
—Endpoint management is a key function for data center management and cloud management. Today's practice to manage endpoints for the enterprise is labor intensive, tedious and error prone. In this paper, we present Universal Script Wrapper, an innovative solution which provides a unique solution to allow users to manage a group of endpoints as if logged in(More)
We study the problem of assigning multiple severity level service requests to agents in an agent pool. Each severity level is associated with a due date and a penalty, which is incurred if the service request is not resolved by the due date. Motivated by Van Meighem (2003), who shows the asymptotic optimality of the Generalized Longest Queue policy for the(More)
—Today's businesses have a wealth of options available to them for running their applications. They can use proprietary infrastructures, private data centers, co-location facilities, or public clouds. Applications can be deployed on native hardware or virtualization can be used to improve consolidation and manageability. Public cloud platforms are growing(More)
