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

[Robin Cover <robin@oasis-open.org>]

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

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..."
