Measured Characteristics of Distributed Cloud Computing Infrastructure for Message-Based Collaboration Applications

Free registration required

Executive Summary

Cloud is an emerging information technology infrastructure designed for rapid delivery of computing resources. It promises to facilitate new applications deployment by highly efficient virtualized compute, storage, and network resources that can be rapidly scaled up and down in a flexible yet secure way to deliver a high quality of service. Cloud computing could potentially be a cost-effective model for provisioning large-scaled, globally deployed collaborative services such as SensaaS (Sensor as a Service) and XaaS ("X is anything" as a Service) as cloud services while making the infrastructure more responsive to the needs of the services. The authors devise a methodology to study the characteristics of distributed cloud computing infrastructure at the network, transport messages, and message-based collaboration applications levels.
