Verifying cloud service-level agreement by a third-party auditor
(
John Wiley & Sons, Ltd.
, 2014 , Article)
In this paper, we study the important issue of verifying service-level agreement (SLA) with an untrusted cloud and present an SLA verification framework that utilizes a third-party auditor (TPA). A cloud provides users ...
Release-time aware VM placement
(
IEEE
, 2014 , Conference Paper)
Consolidating virtual machines (VMs) on as few physical machines (PMs) as possible so as to turn into sleep as many PMs as possible can make significant energy savings in cloud centers. Although traditional online bin ...
Online risk assessment and prediction models for Autonomic Cloud Intrusion srevention systems
(
IEEE
, 2014 , Conference Paper)
The extensive use of virtualization in implementing cloud infrastructure brings unrivaled security concerns for cloud tenants or customers and introduces an additional layer that itself must be completely configured and ...
A Parallel Random Forest Algorithm for Big Data in a Spark Cloud Computing Environment
(
IEEE Computer Society
, 2017 , Article)
With the emergence of the big data age, the issue of how to obtain valuable knowledge from a dataset efficiently and accurately has attracted increasingly attention from both academia and industry. This paper presents a ...
Exploiting Task Elasticity and Price Heterogeneity for Maximizing Cloud Computing Profits
(
IEEE Computer Society
, 2018 , Article)
This paper exploits cloud task elasticity and price heterogeneity to propose an online resource management framework that maximizes cloud profits while minimizing energy expenses. This is done by reducing the duration ...
Efficient datacenter resource utilization through cloud resource overcommitment
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We propose an efficient resource allocation framework for overcommitted clouds that makes great energy savings by 1) minimizing PM overloads via resource usage prediction, and 2) reducing the number of active PMs via ...
Toward SLAs Guaranteed Scalable VDC Provisioning in Cloud Data Centers
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Cloud computing has been a cost-efficient paradigm for deploying various applications in datacenters in recent years. Therefore, efficient provisioning for virtual data center (VDC) requests from different service providers ...
A probabilistic multi-tenant model for virtual machine mapping in cloud systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
A novel probabilistic multi-tenant model is developed to characterize the service performance of cloud systems. The model considers essential cloud-system characteristics including virtualization, multi-tenancy and ...
Regional failure survivability for cloud networking services using post fault restoration
(2013 , Conference Paper)
Cloud computing services are being adopted to expand applications across dispersed data-center sites. As these new paradigms require active data exchange, they impose further virtual network (VN) mappings over operator ...
A hierarchical, autonomous, and forecasting cloud IDS
(
IEEE
, 2013 , Conference Paper)
Cloud computing supports distributed service oriented paradigm, multi-domain and multi-users administrative infrastructure. Due to the distributed nature of the cloud environment, it has high intrusion prospects and suspect ...
