DESCRIPTION
The term "cloud portability" is often considered a synonym for "Cloud API portability," which implies a series of misconceptions. If we break away from dogma, we can find that what we really looking for in cloud portability is Application portability between clouds which can be a vastly simpler requirement, as we can achieve application portability without settling on a common Cloud API. ..The following presentation shows how I could use the ideas from this post and provide a practical cloud portability solution today using Cloudify and JClouds. See details in this post:http://natishalom.typepad.com/nati_shaloms_blog/2011/12/making-cloud-portability-a-practical-reality.html

APP PORTABILITY != CLOUD PORTABILITY (Cont..)
OS (Linux, Windows) looks pretty much the same on all clouds OS runs pretty much the same on all clouds OS are packaged In different image format but that part is abstracted
from the application code anyway. Compute & Storage are pretty common in most clouds
Compute & Storage could be easily abstracted across clouds Elasticity, Scaling, Continues Availability
The same effect on the application regardless of the underlying cloud. The process of scaling & fail-over is done outside the app code
