The following are recommendations, rather than fixed requirements. However, our experience in developing this documentation indicated the following suggestions.

Cloud Controller (CLC)

Hardware	Minimum	Suggested	Notes
CPU	1GHz	2 x 2GHz	For your cloud to scale it helps to have at least a dual core processor
Memory	512MB	2GB	the Java web front end benefits from lots of available memory
Disk	5400rpm IDE	5400rpm SATA
Disk Space	40GB	40GB
Networking	100Mbps	1000Mbps	Cloud controller may be subject to heavy traffic on a busy cloud setup

Walrus Controller (WS3)

Hardware	Minimum	Suggested	Notes
CPU	1GHz	2 x 2GHz	For your cloud to scale it helps to have at least a dual core processor
Memory	512MB	2GB	File serving benefits from the presence of memory for caching
Disk	5400rpm IDE	10000rpm SATA	File serving benefits from fast disk access
Disk Space	40GB	1TB	Disk space will condition image storage as well as user data
Networking	100Mbps	1000Mbps	Walrus may be subject to heavy traffic on a busy cloud setup and image needs to be copied over the network to NC at startup: faster network will mean faster initial instanciation time

Cluster + Storage Controllers (CC + EBS)

Hardware	Minimum	Suggested	Notes
CPU	1GHz	2 x 2GHz	For your cloud to scale it helps to have at least a dual core processor
Memory	512MB	2GB	Block storage serving benefits from the presence of memory for caching
Disk	5400rpm IDE	10000rpm SATA	Block storage serving benefits from fast disk access
Disk Space	40GB	1TB	Disk space will condition block stora capacity
2 Network interfaces	100Mbps	1000Mbps	Cluster will be subject to heavy traffic on a busy cloud setup as it will act as a router for all instances started on NC it Controls and will provide block storage (if needed) to them

Node(s) (NC)

The other system(s) are nodes, which will run the node controller (NC) These systems will actually run the instances. You will need one or more systems with:

Hardware	Minimum	Suggested	Notes
CPU	VT extensions	VT, 64-bit, Multicore	64-bit can run both i386, and amd64 instances; by default, Eucalyptus will only run 1 VM per CPU core on a Node
Memory	1GB	4GB	additional memory means more, and larger guests
Disk	5400rpm IDE	7200rpm SATA or SCSI	Eucalyptus nodes are disk-intensive; I/O wait will likely be the performance bottleneck
Disk Space	40GB	100GB	images will be cached locally, Eucalyptus does not like to run out of disk space
Networking	100Mbps	1000Mbps	machine images are hundreds of MB, and need to be copied over the network to nodes
