The Rackspace Cloud consists of the following networks:
PublicNet connects a Cloud Server to the Internet. When creating Cloud Servers with PublicNet, your servers get an IPv4 and an IPv6 address. Outbound public traffic is billed for per published rates. A Cloud Server can be created without a public network, however, access to operating system updates, Cloud Monitoring remote checks, etc., may not work. See here for more info. (Note: PublicNet is required for RackConnect and Managed Cloud Service Level customers).
ServiceNet is an internal, multi-tenant network within each Rackspace Cloud region and provides Cloud Servers access to regional services such as Cloud Files, Cloud Load Balancers, Cloud Databases and Cloud Backup free of charge. ServiceNet is currently IPv4 only. Historically, ServiceNet was used for Cloud Server to Cloud Server communication, but Cloud Networks is now recommended for this purpose. ServiceNet is also required for Windows Cloud Server activation. It is recommended that Cloud Servers be connected to ServiceNet and all new connections inbound to the server be denied by a software firewall such as IPTables or Windows Firewall. Nonetheless, a Cloud Server can be created without a ServiceNet interface. See here for more info. (Note: ServiceNet is required for RackConnect and Managed Cloud Service Level customers).
Every Rackspace Cloud Infrastructure Service Level account has a default limit of 10 Cloud Networks. To request an increase, please submit a ticket in the Cloud Control Panel with details on how you intend to use the additional networks.
Yes. Each cloud network can be attached to a maximum of 250 Cloud Servers.
Yes. You can add or remove any network (PublicNet, ServiceNet, or Cloud Networks) from a server with an Infrastructure Service Level. However, Managed Cloud Service Level and RackConnect customers are required to have PublicNet and ServiceNet interfaces. This capability means that you can freely make networking changes to your existing deployments without having to rebuild Cloud Servers. Click here for more information. Please be aware that removing PublicNet and/or ServiceNet interfaces may impact certain Rackspace services and capabilities.
Yes. IP addresses on Cloud Networks are usable by any other Cloud Server on that network.
No. At this time, you cannot transfer PublicNet or ServiceNet IP address between Cloud Servers.
The amount of network throughput varies based on the Cloud Server flavor. For more details, see here.
Cloud Networks are regional in scope and can be attached to any of your Cloud Servers in a given region.
