I am the Chair of the Open Glossary of Edge Computing, the Linux Foundation project mentioned in the blog post. I would be happy to invite an OpenStack nominee onto our TSC. We seek to harmonize and define the various flavors of edge, and OpenStack is doing interesting work and I'd like to see the communities collaborate. I am also part of the iMasosn effort.

Hi,
I’m adding the ECG mailing list to the discussion.
I think the root of the problem is that there is no single definition of „the edge” (except for [1< https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_T...]), but it changes from group to group or use case to use case. What I recognise as the commonalities in these edge definitions, are 1) a distributed cloud infrastructure (kind of a cloud of clouds) 2) need for automation or everything 3) resource constraints for the control plane.
The different edge variants are putting different emphasis on these common needs based ont he use case discussed.
To have a more clear understanding of these definitions we could try the following:
- Always add the definition of these to the given context
- Check what other groups are using and adopt to that
- Define our own language and expect everyone else to adopt
Br, Gerg0

Hi all,
Sorry for chiming in really late in this topic, but I think $subj is
worth
discussing until we settle harder on the potentially confusing
terminology.
I think the difference between "Edge" and "Far Edge" is too vague to
use these
terms in practice. Think about the "edge" metaphor itself: something
rarely has
several layers of edges. A knife has an edge, there are no far edges. I
imagine
zooming in and seeing more edges at the edge, and then it's quite cool
indeed,
but is it really a useful metaphor for those who never used a strong
microscope? :)
I think in the trivial sense "Far Edge" is a tautology, and should be
avoided.
As a weak proof of my words, I already see a lot of smart people
confusing these
two and actually use Central/Edge where they mean Edge/Far Edge. I
suggest we
adopt a different terminology, even if it less consistent with typical
marketing
term around the "Edge" movement.
FWIW, we created rough definitions of "edge" and "far edge" during the
edge WG session in Denver.
It's mostly based on latency to the end user, though we also talked
about quantities of compute resources, if someone can find the pictures.
Perhaps these are the pictures Jim was referring to?

That's it, thank you!

I'm involved in some TripleO work called the split control plane:
https://specs.openstack.org/openstack/tripleo-specs/specs/rocky/split-contro... < https://urldefense.proofpoint.com/v2/url?u=https-3A__specs.openstack.org_ope...
After the PTG I saw that the split control plane was compatible with the type of deployment discussed at the edge WG session in Denver and described the compatibility at:
https://etherpad.openstack.org/p/tripleo-edge-working-group-split-control-pl... < https://urldefense.proofpoint.com/v2/url?u=https-3A__etherpad.openstack.org_...
See the picture and table here:
https://wiki.openstack.org/wiki/Edge_Computing_Group/Edge_Reference_Architec... < https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.openstack.org_wiki...
Now, I don't have really great suggestions. Something that came up in
TripleO
discussions [1] is Core/Hub/Edge, which I think reflects the idea
better.
I'm also fine with these names, as they do describe the concepts well. :)
// jim
I'm fine with these terms too. In split control plane there's a deployment method for deploying a central site and then deploying remote sites independently. That deployment method could be used to deploy Core/Hub/Edge sites too. E.g. deploy the Core using Heat stack N. Deploy a Hub using stack N+1 and then deploy an Edge using stack N+2 etc.
John
I'd be very interested to hear your ideas.
