Cross-project discussions about Keystone for Edge at the PTG
by Ildiko Vancsa 12 Aug '18

12 Aug '18

Hi, We’ve started discussions about requirements and architectures options for Keystone in edge scenarios at the Dublin PTG[1][2] which we continued on the Vancouver Forum[3]. To continue the discussion in Denver we plan to have a a joint session with attendees from the Keystone, Edge Computing Group and StarlingX teams to discuss further the requirements and evaluating the possible solutions. You can see the agenda item on the Keystone PTG etherpad[4] already as a placeholder, see under 'Federation Improvements’ (line #50 currently). In case you plan to participate in this discussion please add topics to the Edge Computing Group planning etherpad[5] under the topic ‘Keystone’. Also sign up on the etherpad as attendee if you haven’t done it yet. If you’re planning to attend the PTG, but haven’t registered yet you can find the registration link on the PTG website[6]. Please let me know if you have any questions. Thanks and Best Regards, Ildikó [1] https://etherpad.openstack.org/p/edge-ptg-dublin [2] https://etherpad.openstack.org/p/edge-alans-problems [3] https://etherpad.openstack.org/p/YVR-edge-keystone-brainstorming [4] https://etherpad.openstack.org/p/keystone-stein-ptg [5] https://etherpad.openstack.org/p/EdgeComputingGroupPTG4 [6] https://www.openstack.org/ptg

Gergely, I might have missed this in the meeting this morning. What is the general status of the ‘Federated Keystone in Edge Environment’ TESTING ? i.e. · Are we still in the process of setting up a test environment ? (I think this is the case) · Is there a timeline on when we think o Setup will be done, and o we will be able run some of the tests ? o ( Ideally results would be available for discussion at PTG meetings ) ( Interested in seeing results ) Greg.

Some question: * Do we keep the test design in the etherpad or should I move it to the wiki (I think Wiki is better, but you know this already 😊) * Do we want to test only the Keystone functionality or Keystone + mod shib? * Any comments?

Re: [Edge-computing] Review of Dublin edge notes

09 Aug '18

Hi, Here are the notes from todays meeting: http://eavesdrop.openstack.org/meetings/review_of_dublin_edge_notes/2018/re… We finished the review of the wiki. Thanks everyone for reviewing, I will stop organizing the IRC meetings, but: 1. In case of any further comments and questions just send a message on #edge-computing-group or drop a mail to edge-computing(a)lists.openstack.org<mailto:edge-computing@lists.openstack.org> 2. I plan to have a one hour review session for the whole document on the PTG 3. After the PTG when I've corrected all open issues I will move the content of the wiki to https://wiki.openstack.org/wiki/Edge_Computing_Group/Use_Cases#Requirements… 4. After https://gerrit.opnfv.org/gerrit/#/c/59763/ is merged I will replace the deployment scenarions part with a link to the OPNFV document There are some open questions what we found during this and the previous reviews * In 5.3.4.1 Remote control controlling part what are the operations what should be available? Do we imagine a structure similarly ott he image and keystone data distribution? * How can we make the distinction between the connectivity from the backhaul to the edge site (i.e. inter edge sites), vs the connectivity between the edge site and devops/users that are in the vicinity of the edge site * Regarding the storage of small edge deployment: Is the storage a single, locally attached unit? -> https://gerrit.opnfv.org/gerrit/#/c/59763/ suggests "mainly local storage" * Regarding the storage of small edge deployment: What's about image repository service (i.e. are you expecting a fully indepedent edge node or can we envision to have just a node that behave like a compute node in the OpenStack terminology?) * At edge there can be many vm/cn applications evolve as per the need. Any thoughts on how such app management is taken care. * What should be the size of the all the OpenStack components in the different edge deployment scenarios in terms of CPU, memory, disk and hardware units Any comments or notes are welcome.

Re: [Edge-computing] [opnfv-tech-discuss] Demo Accepted: OPNFV Testing for Open Infrastructure Federation
by fuqiao＠chinamobile.com 09 Aug '18

Hi, all. We have made quite good progress on yesterday's call. Attached is the slides I used yesterday. I think we have reached good consensus on the test scenarios, and 4 possible test cases. We also try to distrubute the whole work into 4 task. And we got Mark and Gabriel stand up on yesterday's call for help on the deployment and test cases development. Julien also contacted me offline after the call that he can also help in the manual deployment and configuration. I would like to say thank you so much for our volunteers. I update the etherpad to include these new updates as well. @Manuel, could you please also share your progress with both Mark and Julien, so that you can collaborate together. OPNFV demo discription and progress updates The following slides discribe the testing scenario, and test cases. https://wiki.opnfv.org/display/EC/Edge+cloud?preview=/20745277/26837474/Key… DEMO TASK If you would like to perticipate in this demo, please also sign your name after each task. •TASK 1: Find lab resource, requirement: -- Julien •two bare metal servers within one lab. •L3 connections between two servers •TASK 2: manually deploy a keystone to keystone environment, follow the instruction from http://www.gazlene.net/demystifying-keystone-federation.html -- Manuel, Mark Beierl, Julien •TASK 3: Try XCI for automating the deployment and configuration process (depend on experience from TASK 2) -- Manuel •TASK 4: develop test cases (depend on environment provided by TASK 2) -- Gabriel, Mark Beierl 中国移动研究院网络与IT技术研究所付乔 15901025951 From: fuqiao Date: 2018-08-02 17:08 To: georg.kunz; gergely.csatari; rsblendido; tim.irnich; ildiko CC: trevor.cooper; periyasamy.palanisamy; zhaoqihui; Manuel Buil; opnfv-tech-discuss; edge-computing Subject: Re: [opnfv-tech-discuss] Demo Accepted: OPNFV Testing for Open Infrastructure Federation Hi, all. We continue the discussion about the keystone demo on ONS on yesterday's edge cloud call and today's EC WG call. The detailed progress are kept in the following etherpad page, under the OPNFV bullet. https://etherpad.openstack.org/p/ECG_Keystone_Testing In general, we have made some progress on the demo setup, the resources for the demo, and the test scenarios. 1, for the lab resource, Julien will help to save some resource for the demo. I guess that will be in one of our ZTE lab? is that right, @Julien? 2, for demo setup, Manuel helps to give some introduction about the current progress for XCI. For now, we think we could promote the demo by deploy XCI twice in one lab, there are some manuel work required to setup the keystone federation. Details about the federation deployment are kept in Colleen's blog. http://www.gazlene.net/demystifying-keystone-federation.html Manuel will help look into this and see if it is possible to automate these. But we may need help from the keystone team. 3, for the test scenarios, Georg propose we could look into the impact of network condition, scalability, and hardware limitation, and see how these aspects can impact keystone federation. I am trying to propose the following 3 test cases, and hope we could continue the discussion next week. TC01: add network delay between user agent and identity provider. See how latency influence the federation mechanism TC02: add bandwidth limitation between user agent and identity provider, see how bandwidth influence TC03: creat a scenario with a number of (e.g. 1M) users authenticate together, from a certain nunber (e.g. 2) of service provider. and see how the scalability is for the identity provider. Such case could also be done when there are latency and bandwidth limitation between the user agent and the identity provider. I would like to invite the keystone team and the edge cloud team to discuss about the test cases together during our next call. Thank you. 中国移动研究院网络与IT技术研究所付乔 15901025951 From: Georg Kunz Date: 2018-07-31 05:33 To: Csatari, Gergely (Nokia - HU/Budapest); fuqiao(a)chinamobile.com; rsblendido; Tim Irnich; ildiko CC: trevor.cooper; Periyasamy Palanisamy; zhaoqihui; Manuel Buil Subject: RE: Re: Demo Accepted: OPNFV Testing for Open Infrastructure Federation Hi all, Thanks Gerg0. In the meantime, I have also added two sections to the etherpad: i) Test dimensions: Here I wanted to sketch test parameters beyond the purely functional tests that are/will be implemented in Tempest. The goal is to investigate how OPNFV test tools and environments can contribute to expanding the test coverage implemented in the OpenStack CI. ii) Setup: we haven’t settled yet on the setup we want to use for the demo. This section summarizes a simple proposal which intends to strike a balance between a fully automatic deployment via XCI and manual steps to get a demo up and running in time. Feedback is very welcome. I am sorry if I missed that, but did we agree on a follow up meeting this week?

Here it is. We *will* need that new sync service, for any service that is expected to sync its state from edge cloud instances to the central cloud of clouds and support that AAA requirement. And highly likely a new or additional data storage solution for that purpose as well. At very least in order to replicate state changes right and resolve conflicts, inevitable for the described AAA case. The issue is mysql/mariadb/galera database transactional consitency models [1], like read committed or repeatable read, do not support that AAA scenario well. Repeatable read transaction isolation level (TI), and stronger consistency models, are "Unavailable" by design (see [1] for the terminology I'm using here). That means it may require the progress to be stopped (no writes accepted and, sometimes, no reads) to maintain DB consistency for the corner cases, like being partitioned/disconnected off the central cloud. But that is a totally accepted situation for AAA, and it expects writes to proceed for edge cloud instances! On the other hand, the read commited transaction isolation level, while "Totally available", provides really poor consistency guarantees IMO, comparing to the better options (see "Sticky Available"). So I believe that new sync service, backed with another data/KV storage solution, must support the best of existing AA consistency models, like "Sticky Available" causal/RTC [2],[3]. While galera et al inter-sites replication of DB, like it was proposed [4] for Keystone federation might not fit the aforementioned consistency requirements/constraints. Its time to consider tools and options for AAA requirement. WDYT?
