OFL: A Language for Cloud Orchestration

摘要

The increasing complexity of Cloud Architecture and the introduction of new paradigms like Internet of Things introduced the problem of creating Value Added Services by composition, not only of Resources, but of Services too. In this work we describe an architectural solution for Orchestration at all Cloud Layers. Here we described a language for orchestrating both resources and services in Cloud. The language manages composition of services and resources in order to create composite service based on Cloud Design Patterns. It is based on a Workflow language for description of composition and it enables verification of composite services by means of Model Driven Engineering techniques, providing a precious and easy-to-use tool for Cloud Engineering.
