2.2.2. Cloud Controller Deployment with One or More Compute Nodes
In this configuration one system acts as the cloud controller by hosting services including the Compute database and API server.
Other available systems are used as Compute nodes on which virtual machine instances are run. Support services such as image storage are provided on either the cloud controller or one or more of the Compute nodes.
Cloud Controller
- Processor
- 64-bit x86 processor with support for the Intel 64 or AMD64 CPU extensions, and the AMD-V or Intel VT hardware virtualization extensions enabled.
- Memory
- A minimum of 2 GB of RAM is recommended.
- Disk Space
- A minimum of 50 GB of available disk space is recommended.Add additional disk space to this requirement based on the amount of space that you intend to make available to virtual machine instances. This figure varies based on both the size of each disk image you intend to create and whether you intend to share one or more disk images between multiple instances.1 TB of disk space is recommended for a realistic environment capable of hosting multiple instances of varying sizes.
- Network Interface Cards
- 2 x 1 Gbps Network Interface Cards.
