Cloud services are widely used nowadays, especially in Infrastructure as a service (IaaS), with vendors offering several purchasing options and expanding the range of services offered on almost a daily basis. Cost reduction is a major factor promoting the adoption of cloud services among enterprises. However, qualitative factors need to be evaluated as well, thus rendering the decision regardin...
Cloud Computing as a computing paradigm recently emerged to a topic of high research interest. It has become attractive alternative to traditional computing environments, especially for smaller research groups that can not afford expensive infrastructure. Most of the research regarding scientific computing in the cloud however focused on IaaS cloud providers. Google App Engine is a PaaS cloud f...
In recent years ad-hoc parallel data processing has emerged to be one of the most important applications for Infrastructure-as-aService (IaaS). Major Cloud computing companies have started to integrate frameworks for parallel data processing in their product portfolio, making it easy for customers to access these services and to deploy their programs. However, the processing frameworks which ar...
Cloud IaaS and PaaS tenants rely on cloud providers to provide network infrastructures that make the appropriate tradeoff between cost and performance. This can include mechanisms to help customers understand the performance requirements of their applications. Previous research (e.g., Proteus and Cicada) has shown how to do this for network-bandwidth demands, but cloud tenants may also need to ...
The private Cloud at the Torino INFN computing centre offers IaaS services to different scientific computing applications. The infrastructure is managed with the OpenNebula cloud controller. The main stakeholders of the facility are a grid Tier-2 site for the ALICE collaboration at LHC, an interactive analysis facility for the same experiment and a grid Tier-2 site for the BES-III collaboration...
Infrastructure as a Service (IaaS) is one of three key cloud market segments, that include also Platform (PaaS) and Software (SaaS). Representing less than third the entire market, this segment projected to keep higher pace growth over next few years. But mainly driven by leaders - technology companies with diversified international business, thereby increasing concentration largest players in ...
Cloud computing is an emerging trend which has progressed to the point of serious adoption in both public and private sector organizations, yet it remains a relatively immature paradigm, one which dictates a revision to the traditional characterization of risk in information technology environments. As a means of an introduction to those changes, this paper offers an overview of the information...
The availability of Infrastructure-as-a-Service (IaaS) computing clouds gives researchers access to a large set of new resources for running complex scientific applications. However, exploiting cloud resources for large numbers of jobs requires significant effort and expertise. In order to make it simple and transparent for researchers to deploy their applications, we have developed a virtual m...
