The parallel execution of requests in a Cloud Computing platform, as for Virtualized Network
Functions, is modeled by an M [X]/M/1 Processor-Sharing (PS) system, where each request …

Abstract For the Processor Sharing queue with batch job arrivals, the sojourn time W of a
single job is investigated. This queuing model is motivated by the evaluation of Cloud …

Cloud computing and its associated virtualization have already been the most vital
architectures in the current computer system design. Due to the popularity and progress of …

We propose simple queueing models for predicting response times of applications executed
in a cloud computing platform under the SaaS model. We assume that each application …

Interesting approaches to counteract performance variability within cloud datacenters
include sending multiple request clones, either immediately or after a specified waiting time …

In this paper, we evaluate the performance of cloud centers with high degree of virtualization
and Poisson batch task arrivals. To this end, we develop an analytical model and validate it …

This paper proposes a novel analytical model for performance evaluation of cloud
computations using G/G/m/m+ K queue. The cloud computing infrastructure allows to …

Cloud computing has revolutionized the information technology era. It offers high-speed
computing, storage, and ICT resources on demand. One of the significant challenges in …

This paper introduces the CPP/M/c model with working vacations to describe queueing
phenomena that arise in an advanced computing environment of virtualized servers …
