Eucalyptus was designed to be easy to install and as non-intrusive as possible. The
software
framework is modular, with industry-standard, language-agnostic communication. Eucalyptus
provides a virtual network overlay that both isolates network traffic of different
users and
allows two or more clusters to appear to belong to the same Local Area Network (LAN).
Also,
Eucalyptus offers API compatability with Amazon’s EC2, S3, and IAM services. This
offers you the capability of a hybrid cloud.
