Cloud spanning is a delivery model for cloud computing in which the applications with requirement of large computational resources for deployment are deployed on multiple clouding environments including private, public or combination of both environments i.e. hybrid environments.
How does Cloud Spanning works?
It fulfills the large resource requirements for deployment using different type of clouding environments.
For an instance, suppose an application requires large storage resources for its deployment then these resources can be supplied by using cloud spanning delivery model. It can take some storage space from a private cloud and some more from a hybrid one.
In this way, all of its required resources for deployment are fulfilled.
How and where It is used?
It is used in scenarios where we want to deploy large applications with larger deployment resource requirements
