Welcome to the Cloud Working Group Wiki

The OMG Cloud Working Group, formed in July 2018, is the successor to the Cloud Standards Customer Council (CSCC), started in 2011.

1. Mission

The OMG Cloud Working Group publishes vendor-neutral guidance on important considerations for cloud computing adoption – highlighting standards, opportunities for standardization, cloud customer requirements, and best practices to foster an ecosystem of open, standards-based cloud computing technologies.

2. Co-Chairs and Members

The co-chairs of the Working Group are, as of March 2021:

  • Claude Baudoin (Principal, cébé IT & Knowledge Management)
  • David Harris (Cyber Architect, IT Value Acceleration, Inc.)
  • Lisa Schenkewitz (Executive IT Architect, IBM)

Co-chair roles and responsibilities are less formal in an OMG Working Group than they are in a Special Interest Group or Task Force. There are no formal policies and procedures about the organization of a WG. However, it is our intent to periodically ask CWG members to formally elect the group's co-chairs.

As of March 2021, membership in the CWG is open, free, and not restricted to holders of an OMG membership. However, co-chairs must be from an OMG member company. You should expect to see some change to the status of OMG working groups during 2021, mostly to better manage intellectual property generated by such groups.

3. Meetings

The CWG largely operates through work performed “off-line” by its members, such as the writing and editing of discussion papers.

In addition, status reviews and discussions of the CWG's roadmap will occur during regular OMG meetings. The initial cadence of meetings, agreed at the 25 Sep 2018 kickoff meeting in Ottawa, is:

  • a face-to-face meeting (half a day or a full day) during the quarterly OMG meeting week, typically on Tuesday;
  • teleconferences as required between OMG meetings.

Our next OMG Cloud WG meetings are scheduled for:


  • Week of March 21-25, Reston, VA, USA
  • Week of June 20-24, Orlando, FL, USA
  • Week of Sept 19-23, Burlingame, CA, USA
  • Week of Dec 5-9, Austin, TX, USA


  • 24 Mar 2021 (virtual event)
  • 15 Jun 2021 (Orlando, FL) hybrid event
  • 28 Sep 2021 (Burlingame, CA)
  • 07 Dec 2021 (Long Beach, CA)

The agenda of our meetings generally follows this pattern:

  • Welcome and Introductions
  • Review of papers completed or started during the previous quarter
  • Special presentation(s) by one or more CWG members, special guests, or representatives of organizations we have a liaison with
  • Review of the potential upcoming paper, participant feedback and prioritization, new suggestions, etc.
  • Discussion of other actions (events, standards efforts, etc.)
  • Agenda items for the following face-to-face meeting.

4. Deliverables per OMG Process

4.1. Discussion Papers

The CSCC created 27 guides or papers during its existence. All of those are now classified as “OMG Discussion Papers,” although they are not being re-published with a new title or cover page at this time. The change in name and branding will occur as the papers are updated. With the new papers added by the OMG Cloud Working group since 2019, there are now 29 guides or papers, listed below.

The roadmap for the writing of new Discussion Papers or the updating of existing ones will be decided by the group as a whole during its meetings. The workflow for each paper will conclude with:

  • the preparation of an “external draft” for review by anyone (including non-OMG members) who cares to comment
  • a four-week review period directed at the members of the appropriate OMG Task Force (for technically-oriented papers, it will be the Middleware and Related Services [MARS] Task Force)
  • a short presentation of the paper, with a summary of edits made as a result of the review, to the Task Force members
  • a Task Force vote to issue the papers.

In general, the last two steps will take place during an in-person Task Force meeting during an OMG Technical Meeting week. In exceptional cases, this may be replaced by an e-mail vote if the Task Force chairs agree, to avoid delaying the paper.

4.1.1. Existing Guides and Papers

We generally raise the possibility of updating an existing paper or guide when it is about three years old. Major reason to update a paper may be:

  • references to obsolete technologies,
  • important evolution of the market,
  • new opinions presented by CWG members,
  • appearance of new standards.

In addition, revisions should address the following objectives:

  • re-branding the paper or guide with the OMG logo, the name of the Cloud Working Group, and the OMG copyright notice,
  • acknowledging authors (some older papers did not contain an acknowledgement section),
  • fixing “link rot” and replacing obsolete links with newer ones,
  • aligning the terminology with the most recent usage (e.g., “CSP” and “CSC” for cloud service providers and customers, respectively),
  • tightening the language when there are repetitions or unnecessary statements,
  • fixing any typos or grammar errors.

4.1.2. Papers or RFIs Proposed or in Progress

Title Leaders Kick-off External Draft Planned Vote
Practical Guide to Data Governance in the Cloud Jean-Claude Franchitti Mar 2021 Jul 2021 Sep 2021

When new papers are released, they may supersede similar considerations previously included in some other papers, in which case those will need to be revised accordingly in due time.

The roadmap for the next cycles (reviewed at each meeting) currently includes:

  • The December 2018 meeting raised the need for a Catalog of Cloud Standards.
  • The December 2018 meeting also raised the potential need to revise the Interoperability Paper (December 2017), in order to add a new scenario about data migration, and mention interoperability patterns. David Harris and Beniamino Di Martino are the initial champions of this proposal.
  • A paper suggested by Karolyn Schalk in February 2021, aimed at clearing up the “jargon” surrounding the proliferation of “XaaS” services.

4.1.3. Important Points about the OMG Publication Process

  • Getting a document approved without too much delay if the final draft is ready a few days after an OMG meeting. The MARS Task Force agreed, during its December 2018 meeting, on the following rules. We will propose that other Task Forces that may be asked to approve other papers follow those rules too, and we will submit them as suggestions to the new Process Subcommittee of the Architecture Board.
    • Approval outside of their regular meetings should be exceptional.
    • The final draft should be distributed four weeks before the vote starts.
    • An e-mail vote will then be administered using normal OMG poll procedures.
  • The OMG standard footer at the bottom of the cover page of a Discussion Paper says that it is not an official position of the OMG.
    • The OMG Technical Director agrees that we want to change this message, which weakens the document, but a new version has not been offered as of March 2021.
    • The standard copyright language on page 3 can occasionally be counter-productive, and exceptions can be granted by OMG's Counsel on a case by case basis. paper, for which we precisely wanted to

4.2. RFIs, RFCs and RFPs

Per OMG policies and procedures, there are now new types of deliverables that the CWG may undertake:

  • RFIs when more information is required from members, users or vendors
  • RFPs when the CWG wishes to solicit a new standard
  • RFCs when there is an existing, uncontested technology that can become a standard

However, RFPs and RFCs can only be issued by a Technical Committee upon recommendation of a Task Force. The CWG will generally request such a recommendation from the Middleware and Related Services (MARS) Platform Task Force, but may from time to time go through another, more relevant Task Force.

5. Call for Participation

5.1. Joining the CWG and the mailing list

Interested OMG and non-OMG participants are invited to join the CWG.

We have a mailing list, If you join the CWG, you will be added to the distribution. To ask to be added to the mailing list manually, or to unsubscribe, please click here, state your request in the message, and press Send.

In 2020, OMG mailing lists will become closed to non-members after a transition period. We will continue to broadcast important news on our LinkedIn group. In order to see all the information generated by the CWG, please bookmark this wiki page and visit it periodically, and consider joining OMG as a member. This will give you access to all of OMG's work, not just the CWG's.

5.2. Contributing to this Wiki

The following people are currently able to edit this wiki directly, and more will be added as appropriate:

  • Claude Baudoin and Karolyn Schalk (co-chairs)

Others should be able to use the discussion box to suggest changes, and the authors will implement the changes or discuss them with the authors of the suggestions. If you encounter any difficulty doing so, please contact Claude Baudoin.

Also contact Claude if you wish to become an author/editor of this wiki. You will be given your own username and password to do so.

This is a list of relevant international and national standards; compliance or certification programs; and other initiatives, strategies, policies, procedures, and governance documents that should be considered when formulating positions, creating documents, or suggesting OMG standardization efforts.

6.1. ISO/IEC JTC 1/SC 38 Standards

In existence:

  • ISO/IEC 23189, Framework for Trust in Processing for Multi-Sourced Data. This actually relates more to the OMG’s Data Governance WG than to the Cloud WG. This will be mentioned to the OMG Data Governance WG co-chairs for their consideration.
  • ISO/IEC 22624, Taxonomy-Based Data Handling for Cloud Services.
  • ISO/IEC 22678, Guidance for Policy Development

In progress:

  • ISO/IEC 23167, Common Technologies and Concepts
  • ISO/IEC 23187, Interacting with Cloud Services Partners
  • ISO/IEC 23188, Edge Computing Landscape. This is coordinated with SC 41 (IoT), whose Working Group 3 (IoT Architecture) is led by Erin Bournival (Dell) who also co-chairs the Standards Task Group (STG) of the Industrial Internet Consortium (IIC). This is more relevant to the IIC than to the OMG, but since Claude Baudoin participates in the IIC STG meetings, he can discuss the connection to the cloud with Erin.
  • ISO/IEC 23613, Service Metering and Billing.

6.2 Other Guidelines

(under construction, in part by collecting references from the existing CSCC guides and white papers, or those sent by members of this group)

7. Events and Conferences

Help us populate this section by sending event listings to the CWG co-chairs. If you attend an event, please take notes and transform them into a subpage of this wiki (we'll explain how – see Section 5.2).

COVID-19 has caused all in-person events to be cancelled since March 2020. Many events became virtual and registration fees are drastically lower (sometimes zero), for those virtual events. This provides an opportunity to stay informed of trends and use cases at low cost.

Next additions planned:

  • a list of past co-authors and editors by topic, to help recruit future contributors
  • list of contributors to the wiki (even if they just made suggestions that I implemented, they deserve recognition)
  • clear instructions on how to be authorized to contribute (i.e., how to get a login ID to be an author)
    • started, but still learning how to set all configuration parameters properly to allow user registration and guest comments with moderation (finding the right compromise between openness and avoiding spam)
  • Add a link to the Cloud Working Group LinkedIn group.

On 04 Sep 2018, Ram Marupudi (Southeastern Grocers) sent suggestions to have a top navigation section and social media links. Some of the suggestions do not need to be fully implemented here, as they are covered by the OMG's Cloud WG website, but they at least need links from the wiki to the full site (which is currently only referenced indirectly when talking about the existing papers and guides).
