Currently there are few standards for interoperability between public and private clouds.
There are a number of ‘forces’ that are shaping the future of cloud computing
Amazon – AWS is still the dominate force in cloud computing. They are the largest and at the same time the most innovative vendor in the space – no mean feat. Amazon is working to working to support interoperability between its offering and private cloud enterprises via a published API.
Rackspace – OpenStack – The community has over 150 members that are dedicated to creating an interoperability model for a variety of cloud configuration. However, OpenStack is still ancient; it’s future as an industry standard is not certain.
VMWare – VMWare claims 80% market share in private cloud deployments. vCloud – The service is based on VMware’s vSphere and vCloud Director (vCD), exposes the vCloud API. vCD is a key part of VMware’s strategy for driving adoption of hybrid clouds. It provides interoperability between VMware-virtualized infrastructures and 3rd party service providers. These service providers are part of VMware’s service provider partner program. Note. It can be challenging integrating public cloud services from vendor that are not VMWare based.
The efforts of the major players is shaping the future of hybrid cloud computing.
