In this session, specifications for describing applications in order to be included in a Cloud environment will be analyzed along with techniques and tools developed within IRMOS for modelling and predicting the resource and QoS requirements. These mainly cover interactive media applications hosted on third-party virtualised resources (storage, processing and networking). These models have value in many stages of the application lifecycle, for example when configuring applications, determining their characteristics, estimating resource needs in advance of execution, when negotiating QoS with service providers, when assessing the probable technical and economic outcomes of provisioning policies and management actions if either the application or resources do not perform as expected or need to be adjusted.
