Infrastructure as a Service (IaaS) is a type of Cloud Computing service delivery model that provides compute, storage, and network resources to the consumers in an on demand manner. In IaaS cloud environment, resource allocation is one of the complex tasks due to the heterogeneous nature of cloud resources and dynamic job requirements to run the jobs. However, the IaaS cloud resource allocation...

Infrastructure as a Service (IaaS) offers hardware resources (computing power, storage and network) as a service to its customers. The customers order these resources in the form of a lease. Aim of any service provider is to make a leasing plan to maximize the number of accepted leases. Opennebula is popular open source toolkit for building IaaS cloud. Opennebula has its own lease manager and i...

Following IT innovations, manual operations have been automated, improving the overall quality of life. This has been possible because an organic topology has been formed among many diverse smart devices grafted onto real life. To provide services to these smart devices, enterprises or users use the cloud. Cloud services are divided into infrastructure as a service (IaaS), platform as a service...

Infrastructure as a Service (IaaS) clouds promise unlimited raw computing resources on-demand. However, the performance and granularity of these resources can vary widely between providers. Cloud computing users, such as Web developers, can benefit from a service which automatically maps performance non-functional requirements to these resources. We propose a SOA API, in which users provide a c...

Current cloud service offerings, i.e., Software-as-a-service (SaaS), Platform-asa-service (PaaS) and Infrastructure-as-a-service (IaaS) offerings are often provided as monolithic, one-size-fits-all solutions and give little or no room for customization. This limits the ability of Service-based Application (SBA) developers to configure and syndicate offerings from multiple SaaS, PaaS, and IaaS p...

In the near future FPGAs will be available by the hour, however this new Infrastructure as a Service (IaaS) usage mode presents both an opportunity and a challenge: The opportunity is that programmers can potentially trade resources for performance on a much larger scale, for much shorter periods of time than before. The challenge is in finding and traversing the trade-off for heterogeneous Iaa...
