<br>
Sorry for chiming in really late in this topic, but I think $subj is worth <br>
discussing until we settle harder on the potentially confusing terminology.<br>
<br>
I think the difference between "Edge" and "Far Edge" is too vague to use these <br>
terms in practice. Think about the "edge" metaphor itself: something rarely has <br>
several layers of edges. A knife has an edge, there are no far edges. I imagine <br>
zooming in and seeing more edges at the edge, and then it's quite cool indeed, <br>
but is it really a useful metaphor for those who never used a strong microscope? :)<br>
<br>
I think in the trivial sense "Far Edge" is a tautology, and should be avoided. <br>
As a weak proof of my words, I already see a lot of smart people confusing these <br>
two and actually use Central/Edge where they mean Edge/Far Edge. I suggest we <br>
adopt a different terminology, even if it less consistent with typical marketing <br>
term around the "Edge" movement.<br></blockquote><div><br></div><div>FWIW, we created rough definitions of "edge" and "far edge" during the edge WG session in Denver.</div><div>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.</div><div>See the picture and table here: <a href="https://wiki.openstack.org/wiki/Edge_Computing_Group/Edge_Reference_Architectures#Overview">https://wiki.openstack.org/wiki/Edge_Computing_Group/Edge_Reference_Architectures#Overview</a></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Now, I don't have really great suggestions. Something that came up in TripleO <br>
discussions [1] is Core/Hub/Edge, which I think reflects the idea better.<br></blockquote><div><br></div><div>I'm also fine with these names, as they do describe the concepts well. :)</div><div><br></div><div>// jim</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I'd be very interested to hear your ideas.<br>
