13. The smart home is a reality
• Computers
• Tablets
• Printers
• Network devices (routers,
storage, WiFi extenders)
• Smart phones
• Smart watches
• Game consoles
• IoT devices
• Smart appliances
• Etc.

14. The scalability challenge for IoT

15. = Edge Server
The solution is to decentralize and extend
the infrastructure to the Edge

16. And beyond the Edge, to the billions of devices
who are located everywhere

17. Distributed Architectures at
the Edge

28. The Edge can help you:
o Achieve scale
o Maximize performance
o Minimize cost
o Improve redundancy
o Provide security
