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
