PaaS-independent approach to provision appropriate cloud resources for SCA-based applications Institut Mines-Télécom
Motivating example ■ ComputePrice SCA-based application 1 Institut Mines-Télécom
Provisioning resources for service deployment o Deploying a service on PaaS steps: 1. Identifying the needed platform resources, 2. Packaging these resources with the service to be deployed, 3. Instantiating and initializing the platform and service resources. o A dedicating resources for each service to be deployed to host and run its service in a specialized MC. 2 Institut Mines-Télécom

Provisioning resources for SCA-application deployment o Deploying an SCA-based application on PaaS steps: 1. Slice the application to elementary entities, − SCA Slicer and Service aggregator tool 2. Package entities in service micro-containers, − MC deployment framework 3. Deploy obtained MCs on PaaS. 4 Institut Mines-Télécom
