Cloud computing is a new computing paradigm that allows users with different computing demands to access a shared pool of configurable computing resources (e.g., servers, network, storage, database, applications and services). Many commercial cloud providers have emerged in the past 6-7 years, and each typically provides its own cloud infrastructure, APIs and application description formats to access the cloud resources, as well as support for Service Level Agreements (SLAs). Such vendor lock-in has seriously limited the flexibility that cloud end users would like to process, when it comes to deploy applications over different infrastructures in different geographic locations, or to migrate a service from one provider's cloud to another.
