Matej Artac (scribe, XLAB): Technical Marketing & Education Ad Hoc update: the ad-hoc had a recent meeting. Focused mostly on short-term goals: updating LinkedIn group, bringing in educational material - internal videos from Gigaspaces has material, target is 5-7 minutes long. This is open to everybody, so reach out to Jeremy and Lowel. Also wiki. Lowell Higley (CA): Thanks Paul! Matej Artac (scribe, XLAB): Shitao gives a report on activities in the NFV Ad Hoc. Juergen Meynert (Fujitsu): https://www.linkedin.com/groups/8505536 without comma works better Matej Artac (scribe, XLAB): Shitao presents https://www.oasis- open.org/apps/org/workgroup/tosca/document.php?document_id=61402 Matej Artac (scribe, XLAB): TOSCA-323 issue created in Jira, some volunteers solving the comments. Target is to resolve issues by the end of this month Matej Artac (scribe, XLAB): There were discussions on gaps between NFV profile and simple profile, identifying also common points. Certain questions are still open. Matej Artac (scribe, XLAB): Deployment flavor discussions with simple YAML group: is currently approved version suitable to address issues? Is simple profile version 1.2 mature enough to provide deployment flavor? Matej Artac (scribe, XLAB): Matt comments that Luc will describe how matching is done and to make it clear that it can be done against properties and capabilities. The schema and grammar will not change much. Matej Artac (scribe, XLAB): Thinh comments on matching that basic grammar is there, there will be needed some examples for new additional enhancements. New members are welcome to help contribute. About maturity, extensive discussions and analysis show that 1.1 can support matching, but requires ugly modelling of nodes. So this path is not recommended. YAML team helped with enhancements already, so 1.2 will be ahead of us in respect on the NFV. Matej Artac (scribe, XLAB): Also about the gaps [table slide]: this the first time TOSCA is producing a new profile. Will it be independent? Will it support just NFV? There has to be a consensus. NFV profiles should be derived from root elements in simple profiles, otherwise it might feel non-mandatory to implement. Matej Artac (scribe, XLAB): Alex commented on grammar changes: any changes need to be generic enough to have support in enterprises and so that it will work for anybody. There will be a rework on other constructs that will surface. So these need to happen in conjunction with the changes for deployment flavors. The questions about profile need to be resolved soon. E.g., should communities be able to create their own profiles? Matej Artac (scribe, XLAB): Matt: deployment flavor is not a universal or top-level concept. It is specific to NFV. He doesn't see this to go in direction of normalizing the changes. Matej Artac (scribe, XLAB): Alex responds that deployment flavors could be used in clouds as well. Matej Artac (scribe, XLAB): So what we do should be acceptable to more than one group of consumers. Matej Artac (scribe, XLAB): Thinh: at minimum, the YAML profile spec should support basic features, specific grammar that supports general deployment flavors. Telcos could then define their own deployment flavors. Matej Artac (scribe, XLAB): Matt: we provide normative types, but can't force you to use them Matej Artac (scribe, XLAB): Thinh: if I implement NFV profile, must I support all the normative types from YAML profile? Matej Artac (scribe, XLAB): Matt: [this discussion is] beyond this call, but fundamental nodes for compute, storage must be in place and must be respected. But if you make a new resource that is not available yet, create your own. CSD02 needs to have types that are more hollow so that implementors can use those instead of resorting to ugly grammar. Matej Artac (scribe, XLAB): Alex wants to build on what Matt is saying. There has to be ability to express connectivity, not just resources. There needs to be a top-down view in terms of application definition Matej Artac (scribe, XLAB): Matt: [in previous comments he] left out connectivity. There is a ConnectTo, which should be a good base model to express dependency between resources. Matej Artac (scribe, XLAB): Paul as a co-chair comments that he feels an increase of consensus. There is a good level of practicality to the real world issues. He asks that the involved members think of customers that need as little confusion as possible. NFV profile is the first profile to actively extend the YAML simple profile, so this is a good opportunity to achieve reasonable extensions. But don't let perfect stand in a way of good enough. Matej Artac (scribe, XLAB): Thinh: on networking and connectivity, NFV offers richer, more complex way of expressing. If YAML extends a base node type for connectivity, that would help. Telcos need connectivity concepts to be correct. Matej Artac (scribe, XLAB): Matt: with endpoints and ConnectsTo [in the current simple YAML profile], there might be too many specific concepts about TCP/IP level, so they will probably try and make these concepts more generic. Matej Artac (scribe, XLAB): There needs to be a graph system for resources and connectivity, there could be just a name that could be subclassed [in the upcoming revisions]. Matej Artac (scribe, XLAB): Chris comments on models for networking. Networking has seen a lot of modelling work [in the industries]. The goal is to work from OMF models to an industry standards. There is effort to transform UML to YANG. So they are starting to talk about translating into TOSCA. Matej Artac (scribe, XLAB): Paul comments that there seems to be an interest in restarting the networking at hoc. Welcomes comments, co-chair candidates on this. Thinh Nguyenphu (Nokia): It is great about future stuff. Now, we need to address the short term, now. Matej Artac (scribe, XLAB): Better than networking ad hoc is a connectivity ad hoc Matej Artac (scribe, XLAB): Thinh: we need something that is functional now, capable to model and deploy. Otherwise vendors will go and do proprietary solutions and never go back. Also, there was last year an agreement to reach a touch point where TOSCA can consume UML and vice versa. This is possible, but requires enormous work. So at the moment we need to look into how to solve this. Thinh Nguyenphu (Nokia): agreed, we need to focus on solving NFV profile. Thinh Nguyenphu (Nokia): could we do it on csd01? Matej Artac (scribe, XLAB): Matt: taking a step back, regarding Shitao's table [of gaps]: this should be about type inheritance. He proposes for CSD02 to strictly address the base types so that the abstract base classes exist that people can use without issues. Solving fundamental modelling problems. Matt Rutkowski (IBM): @Thinh, i think it is important to get our CSD01 with the matching updates and a few other updates and fixes and not wait; Matej Artac (scribe, XLAB): Paul is positive that TC can launch an ad hoc that is needed Matt Rutkowski (IBM): if we can produce a CSD02 in smallest amount of time and restrict scope then why worry about holding up CSD01? Matej Artac (scribe, XLAB): in the short term, CSD01 already saw strengthening in yaml profile - simpler, more powerful to use. Matt Rutkowski (IBM): if we all hold to only address abstract type review / creation for CSD02 and hold off other things we can produce one quickly perhaps shitao li(huawei): When will CSD02 start? Matt Rutkowski (IBM): it can start next week as far as topic/content definition and discussion of abstract types Matt Rutkowski (IBM): as long as Luc can work in parallel to get CSD01 chapter 2 updates for matching done in parallel and build on a few remaining changes Chris may have Matej Artac (scribe, XLAB): Alex: happy to donate room in Intel, Bay area for a face-to-face. Networking pieces for the near-term and frame broader terms for connectivity. Matt Rutkowski (IBM): next week we can see we can agree at the Simple profile WG to limit scope for CSD02 to abstract type review Matej Artac (scribe, XLAB): Thinh: is it possible to build abstract node for storage, compute, ... in CSD01. If we put it in CSD02, there will be a pressure from industry shitao li(huawei): we can create the name of those abstract types first, so tosca-nfv-profile can be used soon, and leave the work of produce the definitions of the abstract types later Matej Artac (scribe, XLAB): Matt: could put it in CSD01, but editors need to agree that this is a good thing, there is also concern about inserting new things and there might be opposition. Make a poll next week. CSD01 needs to go out soon without much delay, Luc is on vacation Matej Artac (scribe, XLAB): Paul thanks Shitao for leading and co-leading the group and for the report today. Matej Artac (scribe, XLAB): Paul talks about nominations for co-chairing the NVD ad hoc Matej Artac (scribe, XLAB): No new nominations, so Alex Vul is the only nominee Paul Lipton (TC Co-chair) public: Suggested Motion: The TC again thanks Fengkai Li for his co-leadership of the TOSCA TC's NFV & SDN Ad Hoc Group (and notes with appreciation the continuing leadership and hard work by Shitao Li), and after an open nomination period hereby appoints Alex Vul as Co-leader with Shitao Li of the newly renamed NFV Ad Hoc Group. shitao li(huawei): so moved Matej Artac (scribe, XLAB): seconded Alex Vul (Intel): thank you! Matej Artac (scribe, XLAB): Motion passed unanimously Matej Artac (scribe, XLAB): Congratulations, Alex! Matt Rutkowski (IBM): @Alex congrats! and welcome Elmer your alter ego as well Matej Artac (scribe, XLAB): Paul reminds that statements of use are required by August 31 meeting Matej Artac (scribe, XLAB): No meeting on August 24 Matej Artac (scribe, XLAB): Paul motions to adjourn the meeting Matej Artac (scribe, XLAB): Juergen seconds Matej Artac (scribe, XLAB): Motion passed unanimously Matej Artac (scribe, XLAB): meeting adjourned
