Will OpenStack in containers be a big topic of discussion. From a high-level I get some of the appeal. But are there improvements in Mitaka that lend itself to stateless compute?

Stuart Miniman top attended sessions at recent summits, @coreoslinux attends, @docker is discussed. Kubernetes is the new hot topic.

Kenneth Hui What do you mean stateless compute? Containers, cloud-native apps, serverless computing?
1 Votes Vote
Kenneth Hui @stu The user survey shows big increase in use of kubernetes as opposed to docker swarm.
1 Votes Vote
Brian Gracely @kenhuiny Swarm seems to be confined to the All-Docker environment, whereas k8s seems to have broader appeal in more frameworks

Keith Townsend Meaning the management layer running in containers ie Heat in a rkt container. It allows for versioning of the mgmt layer. But can OpenStack management nodes easily operate in such an infrastructure.

Mark Collier @kenhuiny user survey showed top 3 technologies of interest were 1) Containers 2) NFV & SDN, 3) Bare Metal.

Russell Bryant It will certainly be discussed. I see OpenStack as very complementary as a platform to run your containers / orchestration system of choice on

Brian Gracely @sparkycollier OpenStack on k8s as an application, or OpenStack with k8s as a container scheduler for applications?

Steve more noise has been made about containers *on* OpenStack but definitely lots of work being done on the backend on containerizing OpenStack itself. Main improvement in Mitaka from this perspective is probably Kolla upgrade support.
2 Votes Vote
Steve Also working on making Kolla a little bit more abstract, easier to plug in different orchestration options (Ansible, Mesos, Kubernetes)
1 Votes Vote
Brian Gracely @xsgordon what's the difference between Magnum and Kolla?
1 Votes Vote
Kenneth Hui @bgracely @xsgordon My understanding is Magnum focuses on containers 4 workloads on OpenStack & Kolla focused on deploying OpenStack using containers.
2 Votes Vote
Steve @kenhuiny yes, there is a bit more flexibility regarding workloads though - folks also using Heat directly or even just rolling their own using e.g. Ansible on older clouds that don't have Murano/Heat yet.
1 Votes Vote
Steve Existing deployments will of course also need an upgrade path to get to containerized OpenStack in the first place (not an issue for greenfield).

Heidi Joy Tretheway Also, User Survey showed Magnum #1 project of interest (44%) followed closely by Manila.

What's New in the Mitaka release that IT Organizations or Developers should care about?

Brian Gracely I saw @sparkycollier talk about Mitaka being more focused on operations and running the platform. Would love to understand more.

Kenneth Hui Be particularly interested in hearing what end users are excited about.

Mark Collier OpenStack Client is really maturing as a standard way to interact with OpenStack powered clouds
1 Votes Vote
Kenneth Hui @sparkycollier That's big. The recent user survey cited APIs as the top reason 4 deploying OpenStack.
0 Votes Vote
Steve From an operational perspective it's great to see rolling upgrade support making its way to more projects, incl. Cinder in Mitaka.
3 Votes Vote
Mark Collier A lot of the user driven improvements were directly from users like Comcast, Time Warner Cable, China Mobile, Yahoo!, Walmart, Deutsche Telekom who've been running in production over time.
1 Votes Vote
Steve also for operators, the ability to combine the distributed virtual router feature with high availability of the layer 3 agent in OpenStack Networking (Neutron)
1 Votes Vote
Kenneth Hui Deployments are still being cited as pain points. What has improved there with Mitaka?
0 Votes Vote
Brian Gracely @xsgordon it's still strange that functionality like "rolling upgrades" doesn't make it into all projects. this is why people struggle with how to understand OpenStack.
0 Votes Vote
Mark Collier @kenhuiny Great point, 97% of users said having a standard API & platform were top business drivers for selecting openstack

Steve @bgracely did someone say something about a big tent?
1 Votes Vote
Kenneth Hui @bgracely I would hope this would make it into at least the core projects. But then we need to define the core projects. :)

Stuart Miniman the user survey is a great resource - April 2016 data just released https://www.openstac...

Brian Gracely In general, how stable is Neutron in Mitaka? That's an area that is frequently called out as needed more work. Is it production ready?
1 Votes Vote
Russell Bryant @bgracely The user survey shows that over 90% (i think?) of deployments are using Neutron, so I'd say so. There's still a lot of variation on the backend, though.
3 Votes Vote
Steve @kenhuiny another aspect is where you can/can't tolerate downtime - arguable different level of need for infra building blocks (neutron, cinder, nova) versus IaaS+ (trove, sahara, etc.) IMO
1 Votes Vote
Steve @xsgordon e.g. Nova rolling upgrades got people a long way, because the VMs stay up while we move everything else around them.
2 Votes Vote
Mark Collier most users are running Neutron in production for the past 2 or 3 releases and with Liberty we actually heard really positive feedback. Mitaka took the stability of Liberty and added some ease of setup improvements for operators.

Steve @sparkycollier it also seems like we are gradually seeing less people stuck many versions behind current releases too - just my eyeball test though

A big theme in the past 2 Summits is enterprise adoption, particularly enterprisey apps. Where are we with that in Mitaka?

Kenneth Hui Do we get to a day where Oracle runs on OpenStack and not just only cloud-native apps?

Stuart Miniman will we see Microsoft or more Google (other than Kubernetes) deeper into OpenStack?

Mark Collier I recently learned of a large bank running Oracle on OpenStack in production, and SAP is also doing a lot to support OpenStack. SAP is doing a keynote in Austin, in fact.

Kenneth Hui @stu Google seems to be getting more involved. They are Foundation members and recently rolled out Cinder backup to GCP https://goo.gl/2IGQz...

Brian Gracely I keep hearing that there is a proposal to add vMotion-like functionality to OpenStack. Is that the last piece needed to get traditional apps on OpenStack?
1 Votes Vote
Mark Collier yes it's great to see google involved, and in fact @cmcluck is joining my keynote to talk about how kubernetes and OpenStack along with @polvi of coreos - Tuesday morning April 26

Steve @bgracely this is delivered by a combination of API hooks for e.g. Nova hooked into existing HA tools (e.g. Pacemaker) number of vendors have this working now, still more failure types to be handled in future though.
1 Votes Vote
Kenneth Hui @bgracely That and VM HA. @russellbryant has written a bunch about it.
1 Votes Vote
Steve @bgracely features like the "mark host down" API added by OPNFV folks allow external HA tools to do their job more efficiently in terms of recovery times in case of e.g. node failure
2 Votes Vote
Mark Collier @xsgordon OPNFV has been working in the community to help OpenStack evolve to meet the needs of the Telecom industry. Collaboration is key!

What's the biggest misperception about OpenStack in the market today?
2 Votes Vote
Sriram Subramanian one needs a large bench to adopt OpenStack
1 Votes Vote
Kenneth Hui I think there is still some misunderstanding about project vs. product. Users expect the project to be a polished product.
1 Votes Vote
Brian Gracely @kenhuiny that's not an unreasonable thing for users to expect
0 Votes Vote
Steve That OpenStack as it exists on openstack.org is a product.
0 Votes Vote
Steve that depends on consumption model, consuming directly from the Open Source fire hose comes with its own challenges. Some operators are able to manage this and contribute back, and we should applaud that, but it's not for everyone.
0 Votes Vote
Mark Collier one is that containers are somehow competitive with OpenStack, when in fact they are just another useful tool that can and will be adopted up and down the stack. Kolla for example is a project to put OpenStack services into containers.
2 Votes Vote
Brian Gracely I was sort of surprised that in 2016, I was still seeing major vendors having to do OpenStack 101 presentations to the market.
0 Votes Vote
Kenneth Hui I think it's right to expect the core/kernel to be polished and stable. But productizing it is often a bigger task.
0 Votes Vote
Steve @sparkycollier I think we create some of this ourselves by talking about OpenStack support for Containers, VMs, and baremetal. Containers really run on one of the latter two "machines".
1 Votes Vote
Mark Collier I think that from within the cloud world we have known what cloud (and openstack) are for years, but when you get outside that bubble your realize a HUGE amount of IT isnt on any kind of cloud. So the 101 talks are still necessary.
0 Votes Vote
Sriram Subramanian @sparkycollier Mark, to put it more bluntly; the idea that COE+ Containers on baremetal obviates the need for OpenStack/ IaaS layer.
0 Votes Vote
Keith Townsend I think it's a general lack of knowledge around the different projects. OpenStack as an umbrella project isn't too well understood.
0 Votes Vote
Brian Gracely @sparkycollier agreed about containers. The PaaS companies are fighting the same misperception. Containers are a thing. Operating them is a much more complicated thing. Many options available.
1 Votes Vote
Heidi Joy Tretheway We see requests for 101 presentations often, and we're working on one with an MVP by early June.

Kenneth Hui Another shameless plug. @radez form Red Hat and I are doing an OpenStack 101 workshop at the Summit. :)
