Cloud computing is a computing paradigm where applications, data, memory, bandwidth and IT services are provided over the Internet. Cloud computing is based on pay per usage model. Cloud service providers provide virtual resources to the cloud users. The ultimate goal of cloud service providers is to gain maximum profit and use resources efficiently. Scheduling refers to a set of policies to co...

The new possibility of accessing an infinite pool of computational resources at a drastically reduced price has made cloud computing popular. With the increase in its adoption and unpredictability of workload, cloud providers are faced with the problem of meeting their service level agreement (SLA) claims as demonstrated by large vendors such as Amazon and Google. Therefore, users of cloud reso...

Cloud service providers mostly offer service level agreements (SLAs) in descriptive format which is not directly consumable by a machine or a system. Manual management of SLAs with growing usage of cloud services can be a challenging, erroneous and tedious task especially for the cloud service users (CSUs) acquiring multiple cloud services. The necessity of automating the complete SLA life cycl...

Cloud-based storage services have established themselves as a paradigm of choice for supporting bulk storage needs of modern networked services and applications. Although individual storage service providers can be trusted to do their best to reliably store the user data, exclusive reliance on any single provider or storage service leaves the users inherently at risk of being locked out of thei...

Video streaming services are trending to be deployed on cloud. Cloud computing offers better stability and lower price than traditional IT facilities. Huge storage capacity is essential for video streaming service. More and more cloud providers appear so there are increasing cloud platforms to choose. A better choice is to use more than one data center, which is called multi-cloud. In this pape...

Despite the advantages and rapid growth of Cloud computing, the cloud environments are still not sufficiently trustworthy from a customer’s perspective. Several challenges such as specification of service level agreements, standards, security measures, selection of service providers and computation of trust still persists, that concerns the customer. To deal with these challenges and provide a ...

Computing and communication technologies have merged to produce an environment where many applications and their associated data reside in remote locations, often unknown to the users. The adoption of cloud computing promises many benefits to users and service providers, as it shifts users’ concerns away from the physical location of system components and toward the accessibility of the system’...

Nowadays the access to a cloud computing environment is provided on-demand offering transparent services to customers. Although the cloud allows an abstraction of the behavior of the service providers in the infrastructure (involving logical and physical resources), it remains a challenge to fully comply with the Service Level Agreements (SLAs), because, depending on the service demand and syst...

Rising trends in the number of customers turning to the cloud for their computing needs has made effective resource allocation imperative for cloud service providers. In order to maximize profits and reduce waste, providers have started to explore the benefits of oversubscribing cloud resources. However, the benefits of oversubscription in the cloud are not without inherent risks. In this paper...

Cloud infrastructure is deployed in healthcare to access various healthcare services over the Internet. Healthcare cloud is used as a tool for patients to query the best medical departments, organizations and other healthcare related hubs. There may exist various service providers corresponding to a specific healthcare service. The major goal is to find the providers that meet with patients’ (u...
