Proposed OASIS CAMP TC: suggestion for consideration of an additional "applicable work" reference

Congratulations to the developers of the Cloud PaaS specification  "Cloud Application Management for Platforms Management" and for  further initiative to support standardization of this technical work in
an OASIS Technical Committee.  Proposal text:
https://lists.oasis-open.org/archives/oasis-charter-discuss/201208/msg00000.html
With respect to the seven enumerated "References" cited at the  end of the proposal text and proposal Section (2)(a)  "Similar or Applicable Work", the TC proposers may wish to take
into consideration also the PaaS usage model document recently  published by the Open Data Center Alliance (ODCA):
ODCA Usage Model: Platform as a Service (PaaS)

Interoperability Rev 1.0
 14 pages   Published August 2012, (c) 2012 Open Data Center Alliance    http://www.opendatacenteralliance.org/docs/ODCA_PAAS_Interop_UM_Rev1.0_BD.pdf
From: Open Data Center Usage Models    http://www.opendatacenteralliance.org/ourwork/usagemodels
I think this document (announced on August 15, 2012) probably
arrived too late to be considered by the proposers.

====================================

From the Executive Summary

====================================

"Platform as a Service (PaaS) is a maturing cloud computing  segment which enables developers and operations staff to  quickly and easily configure and deploy a cloud-ready   application of a particular platform or for a particular
stack, in a linearly scalable, managed container, including  program, database and development tools, and libraries.
Additionally, PaaS provides a managed application hosting
environment that removes the need for the cloud subscriber  to manage the complexities and details of the underlying  infrastructure for an application. Ideally, a properly   architected cloud application can be ported seamlessly
from one PaaS to another, with the benefits of avoiding  vendor lock-in, enabling the use of multiple providers to  host the same application globally, and enabling reliable  and automatic elasticity for the application.
For the purposes of the ODCA, the definition of PaaS is   intentionally constrained to deploying a single application  developed for a specific programming language within a
hosted application container. Cloud providers may offer  support for multiple languages and multi-tenant containers  in their PaaS offering. However, each and every hosted  language is considered an individual PaaS offering. Also,
for the purposes of this document, development, build,  testing, and continuous integration capabilities are  assumed to be orchestrated outside of the PaaS in order  to avoid vendor lock-in.
The ODCA specifically excludes programmable SaaS offerings  from being defined as PaaS offerings. A PaaS, as defined  by the ODCA, explicitly has no SaaS dependency.
While two perspectives of interoperability, interconnectability  and portability, are relevant to PaaS, additional requirements  for interconnectability at the application level are firmly
in the hands of the application developer. It is recommended  that applications developed for PaaS hosting be properly  architected per the ODCA Developing Cloud Capable  Applications*, and be designed to meet the interconnectability
requirements of the ODCA SaaS Interoperability Usage Model**,  where applicable.
This paper outlines five usage scenarios, along with success  and failure scenarios for each. Finally, cloud service
provider requirements and an industry call to action are   presented.
This document serves a variety of audiences. Solution  providers and technology vendors will benefit from its
content to better understand customer needs, and to tailor  service and product offerings. Standards organizations will  find the information helpful in defining end-user relevant  and open standards.

Publication Announcement

================================================

From the ODCA announcement August 15, 2012
http://www.opendatacenteralliance.org/newsroom/mediaresources/#newusagemodels
"The Open Data Center Alliance (ODCA) today published two new
interoperability-focused usage models focused at PaaS and SaaS  accompanied by an foundational document on interoperability   requirements for the cloud. These documents form a clear picture
of customer demands for interoperable solutions regardless of  type of service delivered through the cloud and join previously  published usage models addressing interoperability of IaaS  solutions. The documents detail expectations for market
delivery to the organization's mission of open, industry  standard cloud solution adoption, and discussions have   already begun with providers to help accelerate delivery  of solutions based on these new requirements...
Because cloud applications and services must co-exist and  interact across service providers and enterprise deployments,  it is increasingly important to define and implement
requirements for interoperability. The new usage models,  focusing on PaaS (Platform as a service) and SaaS  (Software as a service) interoperability, ensure that  applications and services operate seamlessly across clouds and providers.
The PaaS interoperability usage model outlines requirements  for rapid application deployment, application scalability,  application migration and business continuity..."
