Resource Requirement Analysis for Web Applications Running in a Virtualised Environment

Analysis of resource usage and precise correlation with the workload that triggered it is essential in order to conduct capacity planning in computing environments. Virtualisation enables resource optimisation and is widely used in grid, cluster and cloud computing. We present an automated approach for resource usage analysis in a virtualised environment that can support capacity planning for web applications. The approach uses Domain Specific Modelling Languages (DSMLs) and model management techniques, which support tool interoperation and provide precise ways for describing resource and request logs and requirements, and automatically generate different outputs that feed into the capacity planning process. The approach is demonstrated using a proof-of-concept example involving a media streaming web application, and the results of the analysis are presented and discussed.
