Keynote 2: Cloud Platforms: Concepts, Definitions, Architectures, and Open Issues

Summary form only given, as follows. Cloud computing is a recent paradigm in information technology enabling an economic model for virtual resources provisioning. In this paradigm, there are three well discussed layers of services known as IaaS for Infrastructure as a Service, PaaS for Platform as a Service and SaaS for Software as a Service. Other XaaS terms are used nowadays to name different resources provided as services in the cloud. In this talk, we will consider Cloud platforms (PaaS layer). We will mainly focus on current architectures and their underlining models. We will in addition consider some open research issues related to cloud platform, e.g. deployment, elasticity and mobility.
