Edge deployment scenarios
Describe the server Server capabilities for different edge deployments and the OpenStack services that run on these servers:
Control nodes host the OpenStack control plane components, and needs certain capabilities:
OpenStack services: Identity (keystone), Image (glance), Placement, Compute (nova), Networking (neutron) with ML2 plug-in
Message Queue, Database server
Network Interfaces: management, provider and overlay
Compute nodes host:
Hypervisor
OpenStack Networking layer-2 agent, layer-3 agent, DHCP agent, metadata agent, and any dependencies
Network Interfaces: management, provider and overlay
Edge Deployments:
Small footprint edge device: only networking agents
Single server: deploy multiple Multiple (one or more) Computes on edge Compute nodes
Single server: Single Controller (partial set of OpenStack services) and Multiple single Controller and multiple (one or more) Computes on an edge server:Compute nodes
HA at edge (Multiple Controller and multiple Computes on at least 3 edge servers for HA:): Multiple Controller and multiple Compute nodes
