Choosing among heterogeneous server clouds

Queue with Heterogeneous Server Under Resequencing Constraint

In this paper, a markovian queue with two types of servers and buffer space is considered. The resequencing constraint is imposed according to which the customers leave the system in the same order in which they entered it. For finite buffer queue, the steady state queue size distribution has been obtained.? 

CS6204: Cumulus, Nimbus, Cumulonimbus – Choosing Between Clouds

Cloud computing is a multi-billion business, with more than 100 cloud service providers [1] vying for supremacy. Businesses are overwhelmed with choices and tradeoffs. In this paper we offer a qualitative and quantitative assessment of leading cloud service providers (CSPs) to guide small and medium businesses (SMBs) in their choice of CSP. Our qualitative study of usability, reliability, and c...

Power-aware server consolidation for federated clouds

Cloud computing has evolved to provide computing resources on-demand through a virtualized infrastructure, letting applications, computing power, data storage, and network resources to be provisioned and managed over private networks or over the Internet. Cloud services normally run on large data centers and demand a huge amount of electricity. Consequently, the electricity cost represents one ...

Choosing Among Alternative Futures

Non-determinism is a serious impediment to testing and debugging concurrent programs. Such programs do not execute the same way each time they are run, which can hide the presence of errors. Existing techniques use a variety of mechanisms that attempt to increase the probability of uncovering error conditions by altering the execution sequence of a concurrent program, but do not test for specif...
