From Fedora Project Wiki



Eucalyptus is a cloud computing software platform for on-premise (private) Infrastructure as a Service clouds. It uses existing infrastructure to create scalable and secure AWS-compatible cloud resources for compute, network and storage.


Current status

Detailed Description

This feature would include version 3.2 of all of the major components of Eucalyptus:

  • Cloud Controller (The central web service stack, web UI, account management, etc.)
  • Storage Controller (analogous to EBS)
  • Walrus (analogous to S3)
  • Cluster Controller (analogous to EC2)
  • Node Controller (which manages the hypervisor on individual compute nodes in a cluster)

It also includes the new web-based User Console for managing cloud resources.

Eucalyptus works with either Xen or KVM, and can use openldap for account management.

Benefit to Fedora

Fedora can be used to build a highly available and scalable AWS-compatible compute/storage cloud.


The main challenge is in packaging a large number of Java dependencies. There is a list of direct dependencies at Eucalyptus, but it does not contain all transitive build dependencies yet. There will also be some distro integration work, but much of this is happening as part of the upstream packaging and release process.

How To Test

1) Install the following packages:

eucalyptus-cloud eucalyptus-sc eucalyptus-nc eucalyptus-cc eucalyptus-walrus

The configuration will default to "SYSTEM" mode for networking, which would allow a single node configuration to work for test purposes.

2) component configuration and registration will mostly follow my blog post from 1/19, though we may script a simpler process for this.

3) Test image launching either with boxgrinder-generated images or with images from Eustore

4) Possibly run through various automated test cases using the Eutester framework

User Experience

Users will have the ability to build an Amazon-compatible cloud and use tools such as boto, euca2ools, BoxGrinder, HybridFox, etc. to manage compute instances and storage.



  • ActiveMQ
  • Axiom
  • Google Web Toolkit
  • Hibernate
  • JasperReports (optional)
  • Mule
  • Spring
  • Axis2c
  • WSDL2C (from Axis2/Java, but may be separated into a fragment package, as Axis2/Java has a huge dependency list)

Contingency Plan

We would punt to F19.


Release Notes

Eucalyptus is an AWS-compatible cloud which allows users to manage compute and storage resources in a private cloud using the same tools and APIs as are used with AWS.
