也許 edge computing 是telco的唯一差別

Web-Scale 和 Telcos 就是不同

http://www.telcotransformation.com/author.asp?section_id=401&doc_id=734673 但telco要能存活一定要學webscale Tom Anschutz:  They have, so I would say "yes" overall. A lot of what they've done, in terms of microservices, is focusing on a sort of computer service model, rather than a functional entity model, which is really core to the whole transition into microservices as  VNFs . That's sort of the big thing. They've [web-scale companies] also improved operational efficiency and what I would call maybe "business efficiency" as well. But in other cases, we don't have as much of an alignment with the large web services companies. Notably, their business typology, or their infrastructure typology, is significantly different. They remain on the bleeding edge of buying more servers, and putting them into a small number of very large locations. They keep taking the technology in one direction, one that we're not close to needing or being at. The fact

still someone in faith on networking

https://www.nextplatform.com/2017/07/17/google-wants-rewire-internet/ Amin Vahdat : We are in a golden age of networking. I won’t tell you the specifics in terms of where we are in our transition plan, but it is an exciting time to be doing networking. For the first time in a long time we have startups in this space. You know it’s funny though, at the same time though the processor speeds are slowing down, or improvements are slowing down, but networking is not really showing signs of slowing. And for me that actually points to a really big opportunity because I think that actually networking is going to be central to improving computing performance overall by enabling us, basically, to leverage more parallelism across servers.
