In a recent interview Vint Cerf, often
referred to as “the father of the internet” was quoted as saying, "We don’t
have any inter-cloud standards. The current cloud situation is similar to the
lack of communication and familiarity among computer networks in 1973." We
at VMware agree that inter-cloud standards are critical to achieve the next
level of interoperability and provide choices to our customers. We have been
working over the past year with other companies in the industry to create and
expand these important standards to fill this void.
About a year ago I began posting about VMware’s
activities working with a number of technology companies to launch the Open Cloud Standards
Incubator which was formed as a committee within the Distributed
Management Task Force (DMTF). The work of the Open Cloud Standards Incubator
was to focus on ways to facilitate operations between private clouds within
enterprises and other private, public, or hybrid clouds by improving the
interoperability between platforms through open cloud resource management
standards. The group also aimed to develop specifications to enable cloud
service portability and provide management consistency across cloud and
enterprise platforms.
Almost a year later cloud computing has become more
mainstream with new products and companies emerging almost daily. Many
companies joined in the important work within the DMTF and have made resource
and technical contributions to its work. 
These contributions include not only VMware’s vCloud API specification,
but submissions by other organizations including HP, Fujitsu and Telefónica.
The group also released an Interoperable
Clouds Whitepaper laying out the existing challenges and
needed inter-cloud standards. The group’s public charter calls for it to complete its initial work soon which will begin the next phase
of work to extend existing specifications and to develop new specifications
where needed.
One of the standards that have emerged as a key
technology for Cloud Computing Interoperability is the DMTF’s Open
Virtualization Format (OVF).  
What started out as a way to package virtual appliances has become an
interoperable way to define and export workloads between clouds, which are
either public or private clouds. OVF has emerged as a common packaging format
and is supported by most of the open cloud APIs that exist today including
VMware’s vCloud
API.
Another important development this year is the launch of
new standards activities in existing and emerging standards organizations. One
of the key organizations that VMware joined is the Cloud Security Alliance.
This organization is focused on defining best
practices as it relates to the implementation of existing security
standards and technologies to the cloud computing paradigm.  Other organizations have launched work and
have developed specifications and programs for standardization including the
Storage Networking Industry Association (SNIA) work in cloud storage standards.
In fact the industry has created a portal to
track all of the work going on in cloud standards along with cloud standards related
events.
We will continue to lead and participate in these
important industry standards activities. We believe working with our partners
and the rest of the industry to develop common interoperable standards is essential
to enable customer choice and for the industry to achieve the full potential of
cloud computing.
