IETF 79 Clouds BoF Proposal (Sept. 2010)
Description of the proposed Clouds Working Group (Charter)
Cloud-based systems are conveniently connected modular blocks of abstracted resources. The resources include —
but not limited to — computing (CPU), communications (bandwidth), memory (storage), management, database,
software, applications, services, security, interconnectivity, etc. Other definitions of Cloud-based systems are
available at Clouds Discussion Archive (http://www.ietf.org/mail-archive/web/clouds/current/maillist.html).
Services over Cloud allow utilization of the abstracted resources to provision, create, securely and trustfully deliver,
and maintain an end-to-end (ETE) service for the duration of its use without any sort of long-term contracts or
commitment to pay for or use the resources. This type of loose coupling of resources (and services) with physical
infrastructure allows rapid repositioning of computing and communication resources and their growth in a costeffective fashion. Unfortunately currently there is no one unified mechanism to support the abstraction of the
resources and their secure and trustful provisioning for developing, managing, and maintaining Cloud-based
services.
The purpose of the IETF Cloud working group (once formed) is to standardize on the Protocols, resource and service
(software/platform/infrastructure as service) provisioning, trust, security, and interoperability methods, Application
Programming Interface (API) profiles for exposing services, mechanisms for logging and auditing for end-to-end
service monitoring, and service management including change management as these apply to within (e.g., intra- and
inter-layer of a Cloud reference framework) the Cloud and between Clouds.
Overlapping work and efforts will be contributed to and synchronized with other relevant groups (e.g., APP/decade,
IRTF/vnrg, TSV/nfsv4, and OPS/netconf).
There is no Standard Cloud Reference Framework in IETF now, so first we may need to agree on a Reference
Framework based on the currently available and widely recognized Cloud Reference Frameworks. End-to-end
monitoring is essential for assuring the service quality of the applications.
This group will identify/develop Protocols, API profiles, data formats to satisfy accessibility, interoperability,
trustworthiness, security and data portability between different implementations of the cloud. These will include the
development of mechanisms for resources abstraction admission control, provisioning for services, scheduling,
monitoring, and logging. The following is a high-level list of work items:
Logging and Auditing of Cloud services
- CloudLog, and CloudAudit
Client and Cloud/Server-side API Profile(s) for Service (including enhancement of existing IETF protocols)
- Public, Private, and Hybrid (toolkit approach)
Virtualization and Hosting (including graceful multi-tenancy support)
- Virtualization of Applications, Services, and Databases
Cloud Reference Framework
- Review/Overview of a Cloud Ref. Framework
Distributed Intra- and Inter-Domain File Systems / Database
- Software/platform/infrastructure as a service
- Distributed Scheduling of resources
Address resolution and extension
- Virtual private network extension to Cloud
Protocols and Interoperability
- Adaptive Protocols for Generic Cloud Services
- Inter-Domain Service-Specific Adaptive Protocols
Security and Trust mechanism as applicable to Cloud Software and Hardware
- Methods, Mechanisms, Process, and Best Practices
Resource and Service Provisioning and Management
- Intra- and Inter-Domain including Change Management
Risk-tolerance, Resiliency, and SLA (RRS)
- Mean time to failure and recovery (MMTF and MMTR) for Cloud resources

- End-to-End assurance of quality for Apps and Services
The resulting specifications will be clear and concise, standards based on that can be easily implemented and interoperated.
Note: All of the Clouds bar BoF presentations and relevant documents are available at the following Website
(http://trac.tools.ietf.org/area/app/trac/wiki/Clouds). The participants are encouraged to review the SDO/WG
survey, Standards gap, reference framework, issues, use cases, and solution requirements documents before the
meeting.
The deliverables of the working group are as follows:
A survey of activities of the Cloud Standards Development Organizations (SDOs) and Working Groups (WGs) will
be conducted and the results will be analyzed for publication as an informational Internet draft. This will be based
on the draft-khasnabish-cloud-survey-00.txt (available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds).
Tentative publication date is March 2011.
A Cloud reference framework will be developed using the currently available and widely recognized Cloud
Reference Frameworks. This will be based on the information that that are being collected in Khasnabish-et-alIETF-78-Cloud-Reference-Framework-v3b-5Aug2010.ppt
(available
at
http://trac.tools.ietf.org/area/app/trac/wiki/Clouds). Tentative publication date is July 2011.
A survey of industry gaps in terms of work items related to exposing Cloud resources, and provisioning and
managing cloud-based services will be conducted. This will not only help us identify the area where open, hybrid,
and proprietary mechanism are utilized, it will also enable us prioritize the work items. This will be published as an
Informational Internet draft (draft-Khasnabish-et-al-cloud-Industry-gap-00) in July 2011 using the materials that are
already
available
in
Khasnabish-et-al-cloud-Industry-gap-v3-Sept10.pdf
(available
at
http://trac.tools.ietf.org/area/app/trac/wiki/Clouds).
A draft on cloud-based video streaming service will be prepared using the mechanism that is presented during IETF78 Clouds bar BoF (draft-wei-dewar-cloud-video-sreaming-00 based on Wei-Dewar-IETF-78-Clouds-bar-BoFCloud-Video-Streaming-29July10.pdf, available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds). This will be
published in July 2011.
A draft related to HTTP enhancement will be developed for use in client and platform side APIs. That draft will be
based on the proposal that has been presented during IETF-78 Clouds bar BoF (Johnston-IETF-78-Clouds-bar-BoFStd-Gap-28July10.pdf) and is available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds. Tentative publication
date for this draft is July 2011.
A draft on maintaining Logs of Cloud services will be prepared using the proposal presented in draft-golovinskycloudlog-00
(Golovinsky-IETF-78-Clouds-bar-BoF-Cloud-Logging-28July10.pptx,
available
at
http://trac.tools.ietf.org/area/app/trac/wiki/Clouds) and the tentative publication date for this draft is July 2011.
A draft on Cloud service auditing will be prepared by Hoff, Johnston, Sapiro, and Reese using the existing drafthoff-cloudaudit-00. Publication date for this draft is November 2011.
Two drafts are being proposed for address resolution and VPN extension to private clouds. These are draft-dunbararp-for-large-dc-* (Dunbar-et-al-IETF-78-Clouds-bar-BoF-Cloud-Address-Resolution-28July10.pdf, available at
http://trac.tools.ietf.org/area/app/trac/wiki/Clouds), and draft-ning-vepc-requirements-* (So-et-al-IETF-78-Cloudsbar-BoF-VEPC-Req-28July2010.ppt, available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds). These are
tentatively scheduled for publication in March 2012.

A draft specifying protocols for supporting and maintaining intra- and inter-domain mobility of resources will be
prepared using the concepts presented in Morrow-IETF-78-Clouds-bar-BoF-Resource-Mobility-28July10.pdf
(available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds). This draft draft-morrow-cloud-resource-mobility00 will be published in July 2012.
The group will also prepare (i) a draft specifying the management information model for virtual networks in
Platform-as-a-Service (PaaS) that are using server virtualization using Okita-Clouds-VNM-model-for-PaaSSept10.pdf (available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds) with publication date of Sept. 2012, and
(ii) a draft on Virtualization and mobility of core IMS (IP multimedia sub-system) resources using Yokota-CloudsTelecom-Net-Virtualization-Sept10.pdf (available at http://trac.tools.ietf.org/area/app/trac/wiki/Clouds) with
publication date TBD.
A few additional proposals are currently being socialized through discussions in clouds@ietf.org and the weekly
conference calls. These include the following: (1) Development of Virtual desktop for mobile clients, and (2) Cloud
security and service trustworthiness. These will be presented during subsequent Clouds meeting, and the related
drafts will be published in future.
