The presentation by Roozbeh Shafiee discusses network design for the Iran OpenStack community, covering essential topics such as IP address planning and the roles of various networks in an OpenStack deployment. It emphasizes the importance of structured IP planning, including public interfaces, internal communications, and redundancy for future growth. The presentation also honors Ian Murdock's contributions to open source software and encourages community engagement through various communication channels.

IP Address Planning
An IP address plan might be broken down into the following sections:
• Subnet router
• Control services public interfaces
• Object Storage cluster internal communications
• Compute and storage communications
• Out of band remote management
• In-band remote management
• Spare space for future growth

Subnet Router
Packets leaving the subnet go via this address, which could be a dedicated router
or a nova-network service.

Control Services Public Interfaces
Public access to swift-proxy, nova-api, glance-api, and horizon come to these
addresses, which could be on one side of a load balancer or pointing at individual
machines.

Object Storage Cluster Internal Communications
Traffic among object/account/container servers and between these and the proxy
server’s internal interface uses this private network.

Compute and Storage Communications
If ephemeral or block storage is external to the compute node, this network is used.

Out of Band Remote Management
If a dedicated remote access controller chip is included in servers, often these are
on a separate network.

In-Band Remote Management
Often, an extra (such as 1 GB) interface on compute or storage nodes is used for
system administrators or monitoring tools to access the host instead of going
through the public interface.

Spare space For Future Growth
Adding more public-facing control services or guest instance IPs should always
be part of your plan.
