Define a reference architecture for edge and far edge deployments including OpenStack services and other open source components as building blocks.


"The most mature view of edge computing is that it is offering application developers and service providers cloud computing capabilities, as well as an IT service environment at the edge of a network." - Cloud Edge Computing: Beyond the Data Center by the OSF Edge Computing Group

"We define Edge computing as an infrastructure deployment focused on reducing latency between an application and its consumer by increasing geographical proximity to the consumer." - Denver PTG (2018) definition

Tiers of computing sites

The below table captures the discussions at the PTG and refers to the definitions we created earlier in collaboration with the OPNFV Edge Cloud Project as they are described in their whitepaper.

OpenStack Denver PTG (2018) OPNFV Edge Cloud Project
Regional Datacenter
  • A large centralized facility located within 100ms of consumers.
  • Typically one deployer will have less than 10 of these.
Large Edge
Edge Site
  • A smaller site located within less than 15-20ms to consumers.
  • One deployer could have hundreds of these.
Medium Edge
Far Edge Site/Cloudlet
  • A smaller site located within less than 10ms to consumers.
  • One deployer could have thousands of these.
Small Edge
Fog computing
  • Devices physically adjacent to consumer (typically within the same building) within 1-2ms of consumers.
  • One deployer could have tens of thousands of these.
