defined. Scenarios that need to be clearly defined within a cloud comput-
ing solution that incorporate an integrator include:
• How an organization interacts with a CSP to manage the CSP
environment
• What access an integrator has to data within a CSP environment
• What actions an integrator may take on behalf of an organization
Failure to address the roles and responsibilities of each party can hinder
the end user's ability to fully realize the benefits of cloud computing. For
instance, if initiating a new instance of a virtual machine requires an
organization to interact with an integrator, then this interaction breaks
the on-demand essential characteristic of cloud computing.
The introduction of integrators to cloud computing solutions can be a
critical element of success for many organizations. However, the introduc-
tion of an additional party to a cloud computing contract requires orga-
nizations to fully consider the most effective method of contracting with
an integrator and clearly define the roles and responsibilities among CSPs,
organizations, and integrators.
Standards
Standards are available in support of many of the functions and require-
ments for cloud computing. While many of these standards were devel-
oped in support of pre-cloud computing technologies, such as those
designed for web services and the Internet, they also support the functions
and requirements of cloud computing. Other standards are now being
developed in specific support of cloud computing functions and require-
ments, such as virtualization.
Security
Placing data on an information system involves risk, so it is critical for
organizations to ensure that the IT environment in which they are storing
and accessing data is secure.
Because of the variability in risk postures among different CSP environ-
ments and differing missions and needs, the determination of the appropri-
ate levels of security vary across organizations and across CSP environments.
