PTG summary on edge discussions
by Ildiko Vancsa 26 Sep '18

26 Sep '18

Hi, Hereby I would like to give you a short summary on the discussions that happened at the PTG in the area of edge. The Edge Computing Group sessions took place on Tuesday where our main activity was to draw an overall architecture diagram to capture the basic setup and requirements of edge towards a set of OpenStack services. Our main and initial focus was around Keystone and Glance, but discussion with other project teams such as Nova, Ironic and Cinder also happened later during the week. The edge architecture diagrams we drew are part of a so called Minimum Viable Product (MVP) which refers to the minimalist nature of the setup where we didn’t try to cover all aspects but rather define a minimum set of services and requirements to get to a functional system. This architecture will evolve further as we collect more use cases and requirements. To describe edge use cases on a higher level with Mobile Edge as a use case in the background we identified three main building blocks: * Main or Regional Datacenter (DC) * Edge Sites * Far Edge Sites or Cloudlets We examined the architecture diagram with the following user stories in mind: * As a deployer of OpenStack I want to minimize the number of control planes I need to manage across a large geographical region. * As a user of OpenStack I expect instance autoscale continues to function in an edge site if connectivity is lost to the main datacenter. * As a deployer of OpenStack I want disk images to be pulled to a cluster on demand, without needing to sync every disk image everywhere. * As a user of OpenStack I want to manage all of my instances in a region (from regional DC to far edge cloudlets) via a single API endpoint. We concluded to talk about service requirements in two major categories: 1. The Edge sites are fully operational in case of a connection loss between the Regional DC and the Edge site which requires control plane services running on the Edge site 2. Having full control on the Edge site is not critical in case a connection loss between the Regional DC and an Edge site which can be satisfied by having the control plane services running only in the Regional DC In the first case the orchestration of the services becomes harder and is not necessarily solved yet, while in the second case you have centralized control but losing functionality on the Edge sites in the event of a connection loss. We did not discuss things such as HA at the PTG and we did not go into details on networking during the architectural discussion either. We agreed to prefer federation for Keystone and came up with two work items to cover missing functionality: * Keystone to trust a token from an ID Provider master and when the auth method is called, perform an idempotent creation of the user, project and role assignments according to the assertions made in the token * Keystone should support the creation of users and projects with predictable UUIDs (eg.: hash of the name of the users and projects). This greatly simplifies Image federation and telemetry gathering For Glance we explored image caching and spent some time discussing the option to also cache metadata so a user can boot new instances at the edge in case of a network connection loss which would result in being disconnected from the registry: * I as a user of Glance, want to upload an image in the main datacenter and boot that image in an edge datacenter. Fetch the image to the edge datacenter with its metadata We are still in the progress of documenting the discussions and draw the architecture diagrams and flows for Keystone and Glance. In addition to the above we went through Dublin PTG wiki (https://wiki.openstack.org/wiki/OpenStack_Edge_Discussions_Dublin_PTG) capturing requirements: * we agreed to consider the list of requirements on the wiki finalized for now * agreed to move there the additional requirements listed on the Use Cases (https://wiki.openstack.org/wiki/Edge_Computing_Group/Use_Cases) wiki page For the details on the discussions with related OpenStack projects you can check the following etherpads for notes: * Cinder: https://etherpad.openstack.org/p/cinder-ptg-planning-denver-9-2018 * Glance: https://etherpad.openstack.org/p/glance-stein-edge-architecture * Ironic: https://etherpad.openstack.org/p/ironic-stein-ptg-edge * Keystone: https://etherpad.openstack.org/p/keystone-stein-edge-architecture * Neutron: https://etherpad.openstack.org/p/neutron-stein-ptg * Nova: https://etherpad.openstack.org/p/nova-ptg-stein Notes from the StarlingX sessions: https://etherpad.openstack.org/p/stx-PTG-agenda We are still working on the MVP architecture to clean it up and discuss comments and questions before moving it to a wiki page. Please let me know if you would like to get access to the document and I will share it with you. Please let me know if you have any questions or comments to the above captured items. Thanks and Best Regards, Ildikó (IRC: ildikov)

OSF Edge Computing Group BoF at ONS EU at the time of the Tuesday call
by Ildiko Vancsa 21 Sep '18

21 Sep '18

Hi, As a few of us will be at ONS EU next week the weekly working group call on Tuesday (September 25) will be “co-located” with a BoF session around Edge at ONS EU in Amsterdam. The session’s purpose is to explore use cases and current ongoing design, development and testing activities under the OpenStack Foundation umbrella, OPNFV, ONAP, Akraino and so forth and to identify next steps. You can find more details about the session here: https://onseu18.sched.com/event/GZqk/edge-computing-group-at-ons-europe I will setup Zoom just like for the weekly call with the usual link (https://zoom.us/j/879678938) we use every week. Please let me know if you have any questions. See you next week in Amsterdam or on the Zoom call! :) Thanks and Best Regards, Ildikó

MVP Edge Architecture
by Waines, Greg 15 Sep '18

15 Sep '18

Hey James, I dumped my understanding of the MVP Edge Architecture from yesterday into some slides ... before I forget it all :) . Let me know if you think this accurately reflects yesterday afternoon’s architecture discussion in the edge-computing group. https://www.dropbox.com/s/255x1cao14taer3/MVP-Architecture_edge-computing_P… NOTE: I did have one question in red on Slide 5 Greg.

PTG information and agenda
by Ildiko Vancsa 12 Sep '18

12 Sep '18

Hi, The next PTG (https://www.openstack.org/ptg) is just around the corner staring next Monday (Sept 10) and ends on Friday (Sept 14). As most of you know this is a developer focused event to provide space and time for face to face technical discussions relevant to the work the project teams are doing and for cross-project collaboration. To emphasize on collaboration you will find representation from all the projects under the OpenStack Foundation umbrella and the event is also co-located with the OpenStack Ops Meetup. The Edge Computing Group is meeting on Tuesday in Ballroom A (https://web14.openstack.org/assets/ptg/Denver-map.pdf) from 9am MDT. You can find our agenda on this etherpad: https://etherpad.openstack.org/p/EdgeComputingGroupPTG4 As mentioned earlier we will do our best to provide an option to participate remotely. I will post a Zoom link and dial-in info on the etherpad above before the sessions start on Tuesday. I will also distribute the information here on the mailing list. As the time slots on the agenda are estimates we are using a dedicated web page (http://ptg.openstack.org/ptg.html) to track the current and next topics and also a dedicated IRC channel (#openstack-ptg) for communication and news sharing. You can find the links to all PTG related resources here: http://ptg.openstack.org Also please note that the weekly call this week is in the APAC time slot, Thursday 0700 UTC and we are cancelling next week’s meeting due to the discussions taking place at the PTG. Please let me know if you have any questions about the event or the Edge related sessions. Thanks and Best Regards, Ildikó
