SYBL: An Extensible Language for Controlling Elasticity in Cloud Applications
The Cloud Application Management Framework (CAMF) enables Cloud application developers to design, deploy and manage their applications through an intuitive blueprint design. In this paper we show how Cloud application developers can utilize CAMF in order to have portable applications that can be deployed on different IaaS with minimal effort. Towards this goal, we introduce the Cloud Application Requirement Language (CARL). CARL can be used for defining the application software and hardware requirements, information that is then included into the TOSCA description of the Cloud application, alongside the application blueprint. CAMF's Information Service utilizes both these artifacts to provide IaaS specific configurations that fulfill the user's requirements.
