Even though the cloud has greatly simplified the capacity provisioning process, it poses several novel challenges in the area of Quality-of-Service (QoS) management. QoS denotes the levels of performance, reliability, and availability offered by an application and by the platform or infrastructure th...
In addition, countermeasures to potential security threats are also presented for each cloud model. Copyright 2016 John Wiley & Sons, Ltd. 展开 关键词: cloud computing security issues and challenges service delivery models taxonomy DOI: 10.1002/sec.1585 被引量: 2 ...
Cost Based Ranking Service Models in Cloud Computing Cloud Computing is an emerging technology where user can store and access services logically over the internet rather than a local server or a computers ha... A Dhivya.,M Saravanan. 被引量: 0发表: 0年 Benefits and challenges of three clou...
Auditing in Cloud ComputingAlthough cloud computing provides numerous advantages, one of the main challenges is ensuring and verifying the reliability of cloud services. If a customer signs a service contract guaranteeing a certain level of availability, how does the customer know whether the provider ...
Therefore, composite network–Cloud service provisioning becomes one of the main networking challenges in Cloud computing. In this paper we tackle the problem of modeling and optimization for composite network–Cloud service provisioning. We first present a system model in which a Network-as-a-...
CHALLENGES FOR ADOPTING CLOUD-BASEDSOFTWARE AS A SERVICE (SAAS) IN THE PUBLICSECTOR Technological advances such as the creation of bandwidth, modular applications and cloud computing have enabled the creation of a distributed collaborative sourcing model named Software as a Service (SaaS). SaaS present...
We consider two major challenges. The first challenge is to find an appropriate market model in order to enable the DC platform. The second is to select suitable collaborative partners to provide services. We propose a novel combinatorial auction-based cloud market model that enables a DC ...
We expose and explore technical and trust issues that arise in acquiring forensic evidence from infrastructure-as-a-service cloud computing and analyze some strategies for addressing these challenges. First, we create a model to show the layers of trust required in the cloud. Second, we present ...
On-Demand:This is a pay-as-you-go plan billed on a per-second or per-hour basis, depending on usage; this model is all about flexibility, scalable with no upfront commitments. Instance-Based:In this model, costs correlate with the cloud instances or virtual servers being used; the bill...
