==================================================
A. Introduction
==================================================
The U.S. government has initiated the rapid deployment of Cloud services for internal
and public use. There are many risks associated with possible lack of interoperability,
portability, and proven security for existing Cloud implementations. In the future,
emerging standards as documented in the Standards Roadmap document will help
solve this problem. While these standards are maturing, best practices can be used to
avoid vendor lock-in, Cloud silos, and security gaps.
1

The purpose of this draft is to list some best practices for Cloud implementation and
organizational support based on past experience with similar technologies e.g. service
oriented architectures. Accompanying each recommendation will be References to the
NIST Cloud Synopsis and Recommendations Draft (Draft-NIST-SP800-146), the NIST
Cloud Working Group outputs, and major external documents to provide context. See
Section E for all Primary References including NIST, US Government, UK Government,
Open Data Center Alliance, Cloud Standards Customer Council, and European sources.
Associated with each recommendation, there is also suggested support from Cloud
Providers and a link to guidance in implementing the recommended best practice. The
next step should be to expand and extend the current content to provide detailed
guidelines (e.g. patterns) for public sector Cloud Computing.
==================================================
B. Implementation Best Practices
==================================================
It is possible to reduce the cost and implementation time for individual projects using
Cloud resources. However best practices for implementation will be needed to ensure
that downstream costs for system integration, migration, operations, and maintenance
do not overwhelm the advantages of the initial deployment. The general principle is to
consider potential future requirements when planning Cloud projects.
-------------------------------------------------------------------------------------
1. Design for Future Portability and Interoperability across Multiple Clouds
-------------------------------------------------------------------------------------
a) For SaaS, ensure that data, documents, and other resources can be moved in and
out of the Cloud using government-approved formats
b) For PaaS, avoid proprietary single Cloud tools and languages for application
development, monitoring, and management
c) For IaaS, enable multiple external Clouds to be used for Cloud bursting and hybrid
Clouds
These recommendations will probably require the use of adaptors and brokers while
standards are emerging.

1.2 Possible Support from Cloud Providers
a) Support standard well-defined formats for importing and exporting data for SaaS
b) Support application generation from multiple tools and standard models
c) Support standardized VM movement and interfaces between IaaS Clouds and
enterprise systems

1.4 Practical Guide to Cloud Computing (Step 4. Select a Cloud Service Model)
-------------------------------------------------------------------------------------
2. Define Government Approved Data Interfaces and Formats for Creating,
Reading, Updating, Deleting, and Batch Movement of Cloud Data and Documents.
-------------------------------------------------------------------------------------
a. Transferring data between Clouds will be necessary for future interoperability and
portability. Official standards e.g. Storage Networking Industry Associations’s (SNIA)
Cloud Data Management Interface (CDMI) and Open Grid Forum’s (OGF) Open
Cloud Computing Interface (OCCI) will simplify this transfer in the future. In the short
run, the government should define approved interfaces and formats that can migrate
to emerging official standards. Adaptors may be necessary to proprietary Cloud
interfaces and formats. Cloud providers should be requested to supply these
adaptors as part of the procurement process.
b. Contractual agreements should be used to penalize Cloud Providers for failure to
support data operations (e.g. data deletion) using government approved data
interfaces and formats.

-------------------------------------------------------------------------------------
3. Use Emerging Standards (e.g. DMTF’s Open Virtual Format) for Moving VMs
between Infrastructure as a Service (IaaS) Clouds
-------------------------------------------------------------------------------------
OVF is an ANSI standard that is becomingly increasing mature.See the NIST SAJACC
WG’s VM Portability White Paper for a detailed discussion. OVF 1.1 is ANSI INCITS
469 2010 is . being submitted to JTC 1 as a PAS submission. DMTF is engaged in
consideration of a subsequent version that may have relevance in the not too distant
future.

-------------------------------------------------------------------------------------
4. Implement a Federated Authentication Capability across Clouds
-------------------------------------------------------------------------------------
A federated authentication mechanism will enable more efﬁcient access to multiple
Clouds. This could be accomplished by the use of a cloud broker layer or future
standards.

4.3 Guidance - Choosing a Federated Authentication Capability
- Choosing the Right federation from GFIPM
http://gfipm.net/choosing-the-right-federation.html
-------------------------------------------------------------------------------------
5. Use Portable Tools for Monitoring and Managing Cloud Resources if possible
-------------------------------------------------------------------------------------
The use of portable tools will facilitate portability if necessary across Cloud providers
(e.g. IaaS). It will also be useful for multiple Cloud architectures. .
5.1 References:

- How to Select Tools for Managing the Clouds
http://www.cioupdate.com/trends/article.php/3919446/How-to-Select-Tools-to-Manage-the-Cloud.htm
-------------------------------------------------------------------------------------
6. Develop a Framework for Orchestrating Processes across Multiple Clouds and
Enterprise Systems
-------------------------------------------------------------------------------------
One of he most difficult tasks will be orchestrating processes across multiple
heterogeneous Clouds and possibly including enterprise systems. A pre-defined
framework to support these process will reduce deployment complexity, cost, and time.
The framework should utilize standards when possible. If there are no standards, cloud
brokers and adaptors can be used following government policies to avoid lock-in.

-------------------------------------------------------------------------------------
7. Choose Non-mission Critical Applications for initial Cloud deployments.
-------------------------------------------------------------------------------------
It is prudent to gain experience and confidence in Cloud resources before migrating
mission-critical applications. Some examples include productivity applications (SaaS),
test and development (IaaS), offloading high transient processing (IaaS),
and hosting Web sites (PaaS or IaaS)

==================================================
C. Policy Best Practices
==================================================
The efﬁcient deployment of multiple Cloud Computing solutions across government (or
any large enterprise) departments will require a common policy framework to enable
future interoperability, portability, reuse of resources, and trusted security.
-------------------------------------------------------------------------------------
8. Develop an Enterprise Catalog to Enable the Discovery of Existing and
Available Cloud Resources
-------------------------------------------------------------------------------------
One of the advantages of Cloud computing is the ability to share resources across
projects and agencies. A catalog of existing resources and access procedures will add
value and reduce costs as the number of Cloud deployments increase. An “application
store” capability can be used to make existing resources available to new projects.

Enterprise Services)
-------------------------------------------------------------------------------------
9. Document Business Use Cases using the Template from the Business Use
Case Working Group
-------------------------------------------------------------------------------------
The Business Use Case Working Group has developed a template for describing Use
Cases and used it to document several examples. Employing a standard template will
foster a more standardized development process and make it easier to exchange
information across projects.

9.4 Practical Guide to Cloud Computing (Step 2. Develop Business Justification
and a Strategic Plan)
-------------------------------------------------------------------------------------
10. Document Standardized Ways of Comparing Cloud Capabilities for
Procurements and Cloud Brokers
-------------------------------------------------------------------------------------
A standard way of comparing product offerings and prices will be valuable for
procurement decisions.

Level Agreements)
-------------------------------------------------------------------------------------
11. Use Simulated-based Acquisition for Cloud Solutions if possible.
-------------------------------------------------------------------------------------
Simulation-based acquisition is a procurement practice that uses simulated test
evaluations before finalizing procurement and full scale development. It has been
advocated in the past but in many cases full scale simulation was prohibitively costly in
time and resources. Cloud environments for test and evaluation can significantly reduce
these costs and enable early simulation-based evaluations of potential Cloud solutions.
It is also possible to evaluate Cloud solutions on internal simulation testbeds e.g NIST’s
Koala.

-------------------------------------------------------------------------------------
12. Establish a Data Governance Policy for When and How Specific Types of Data
can be Stored on Externally Hosted Clouds
-------------------------------------------------------------------------------------
Maintaining strict control of critical data is essential for security, privacy, and trusted
government operations. A clearly stated policy should be documented and enforced
internally and contractually with external resource providers

-------------------------------------------------------------------------------------
13. The US Government should work with other Governments and International
Organizations to develop Policies and Standards enabling future Interoperability
and Portability across Clouds while preserving national security and legal
requirements
-------------------------------------------------------------------------------------
In the future, there will be applications and data that will be shared across international
public sector Clouds for multinational collaboration initiatives (e.g. scientiﬁc research). It
will be necessary to work with other governments and international organizations (e.g.
ISO) to ensure that Clouds will support interoperability and portability requirements. This
will require coordination at the technical level (e.g. standards) and policy agreements.

-------------------------------------------------------------------------------------
14. Maintain Updated Reference Documents including Cloud Standards Catalogs,
Reference Architectures, Technology Roadmaps, and Best Practices.
-------------------------------------------------------------------------------------
Since Cloud technology and related standards are changing rapidly, it will be necessary
to update Cloud information document periodically during the next few years (e.g. once
a year). Experience with speciﬁc Cloud tools, services and resources should be
captured and made available for future government Cloud projects.

==================================================
D. Organizational Best Practices
==================================================
In order to ensure that best practices are followed, it will be necessary to have a
supporting organizational structure. The Cloud organizations can coordinate the sharing
of information, resources, and guidelines across agencies and projects. The examples
are a logical breakdown of responsibilities which can be allocated to groups chosen by
government IT executives. See Federal Cloud Computing Strategy (Section IV. 6

WG’s Cloud Standards Inventory
c) Tracking the standardization requirements of government Cloud deployments and
determine priorities
d) Disseminate information about standards to projects and convey prioritized
government standards requirements to standards development organizations
e) Recommend standardizations to be used on government Cloud deployments
f) Define compliance tests to verify conformance of Cloud resources with standards
specifications
Standards that should be monitored include SNIA’s Cloud Data Management Interface
(CDMI) and OGF’s Open Cloud Computing Interface (OCCI).
