Content delivery networks were all about edge
networking before edge networking was sexy, but the
primary purpose of a CDN is localized storage, not
localized compute cycles. Now Ericsson hopes to
combine the two.
The most practical use cases for edge computing are
still being determined, but (they are) demonstrating an
application that analyzes real-time video and attempts
to identify objects in the video stream.

10. Wait, what is Edge Computing?

16. There is no edge
of the Internet

18. Device

19. Telecom

20. Edge Cloud

21. Cloud

22. There are some… problems.

23. Device

24. Advantages
• Single-tenant
• Near zero latency
• Low-cost
Challenges
• Local state only
• Limited power
• Limited bandwidth

25. Applications
• Applying models computed at origin
• Communication between local devices (IoT)
• Privacy!
• Some day: True peer-to-peer distributed computations.

27. Device level edge computing is not new.

28. Device

29. Telecom

30. Advantages
• Very low latency
Challenges
• Limited state
• Limited power
• Questionable economics

31. Applications
• Packet-level routing and shaping
• ???

32. Telecom

33. Edge Cloud

34. oh wait, that’s us…

35. Advantages
• Low latency
• Powerful servers
• Distributed state
• High-speed interconnection
Challenges
• Not unlimited power
• Keeping security bulletproof

37. git branch tyler/do-not-ever-merge-this

38. lua %{
function fact (n)
if n == 0 then
return 1
else
return n * fact(n-1)
end
end
}%
sub vcl_recv {
set req.http.Factorial5 = lua_call("fact", 5);
}

39. Software Fault Isolation

40. The Problem:
Run tens of thousands of
processes per second.
Each secure and isolated.
At near native speeds.

49. So that’s what we did.

50. What does this mean for you?
