interfaces. Organizations will want the flexibility to create new solutions
enabled by data and applications that interoperate with each other regardless of
where they reside (public clouds, private clouds that reside within an
organization’s firewall, traditional IT environments or some combination). Cloud
providers need to support interoperability standards so that organizations can
combine any cloud provider’s capabilities into their solutions.
Data and Application Portability
Without standards, the ability to bring systems back in-house or choose
another cloud provider will be limited by proprietary interfaces. Once an
organization builds or ports a system to use a cloud provider’s offerings,
bringing that system back in-house will be difficult and expensive.
Governance and Management
As IT departments introduce cloud solutions in the context of their traditional
datacenter, new challenges arise. Standardized mechanisms for dealing with
lifecycle management, licensing, and chargeback for shared cloud infrastructure
are just some of the management and governance issues cloud providers must
work together to resolve.
Metering and Monitoring
Business leaders will want to use multiple cloud providers in their IT solutions
and will need to monitor system performance across these solutions. Providers
must supply consistent formats to monitor cloud applications and service
performance and make them compatible with existing monitoring systems. 
It is clear that the opportunity for those who effectively utilize cloud computing in
their organizations is great. However, these opportunities are not without risks and
barriers. It is our belief that the value of cloud computing can be fully realized only
when cloud providers ensure that the cloud is open.
The Goals of an Open Cloud
Customers expect that the cloud services they use will be as open as the rest of
their IT choices. As an open cloud becomes a reality, business leaders will benefit
in several ways.
Choice
As an organization chooses a provider or architecture or usage model, an open
cloud will make it easy for them to use a different provider or architecture as
the business environment changes. If the organization needs to change
providers because of new partnerships, acquisition, customer requests or
