Lab architecture

This Openstack Lab is composed of one region (fr1) and two availability zones (az1 and az2).

In the first availability zone :

• 3 compute nodes (aka hypervisors) for Nova
• 1 Ceph cluster for Cinder
• 3 bare metal nodes for Ironic

In the second availability zone :

• 3 compute nodes
• 1 Ceph cluster

Lab architecture

The different networks are :

• fr1-az1 : provider network in AZ1 (flat, i.e. without VLAN, shared, i.e. available for everybody and external, i.e. managed outside Openstack)
• fr1-az2 : provider network in AZ2
• ironic : external VLAN for bare metal nodes (only available in AZ1)
• octavia : external VLAN for Octavia management (only available in AZ2)
