An important tenet of on-premise cloud computing is that it takes advantage of an organization's existing resources and organizational infrastructure

Eucalyptus Systems, Inc., creators of the leading open source private cloud platform, today announced the first major update of the open source Eucalyptus cloud computing software since it was launched. The latest version of Eucalyptus features new multi-cluster support and enhanced concurrency management for improved scaling, enabling users to seamlessly overlay their Eucalyptus cloud on top of virtually any existing IT infrastructure, regardless of size or configuration. Eucalyptus now also includes new monitoring capabilities to deliver ongoing visibility into the status of an organization's on-premise cloud. This newest version of Eucalyptus is available today and can be downloaded at

This news follows the company's announcement last week that Eucalyptus software is the engine behind the Ubuntu Enterprise Cloud (UEC), a new cloud computing solution packaged in the latest version of the popular Ubuntu Linux distribution. UEC powered by Eucalyptus will ship with every copy of Ubuntu 9.10 Server Edition, which is available now at

"An important tenet of on-premise cloud computing is that it takes advantage of an organization's existing resources and organizational infrastructure," said Dr. Rich Wolski, co-founder and CTO at Eucalyptus Systems. "Our goals for this significant new release are two-fold. First, we enhanced the flexibility with which Eucalyptus can be deployed so that it can take greater advantage of the IT hardware, software, security, and organizational policies already in place in the data center. Secondly, we have concentrated on engineering better performance into the platform itself to enhance scale. We believe that these features will provide the benefits of Eucalyptus on-premise cloud computing to virtually any organization."

Eucalyptus is an open source software infrastructure for implementing on-premise cloud computing using an organization's own IT infrastructure. Eucalyptus turns data center resources such as machines, networks, and storage systems into a cloud that is controlled and customized by local IT. With Eucalyptus, businesses of any size can leverage their own IT resources to get the benefits of cloud computing without the concerns of lock-in, security ambiguity and unexpected storage costs that can be associated with public clouds.

Eucalyptus is the only cloud architecture to support the same application programming interfaces (APIs) as public clouds, and today, with the release of version 1.6.1, Eucalyptus is the only on-premise cloud platform that is fully compatible with the Amazon AWS public cloud infrastructure. By virtue of its open source foundation and seamless interoperability with other major clouds, Eucalyptus delivers an unmatched level of flexibility and freedom, enabling users to successfully avoid the pitfalls associated with getting locked in to a specific vendor's cloud infrastructure.

"We have been running Eucalyptus in our production environment for over six months and have been extremely satisfied with the technology," said Guy Naor, CTO of Morph Labs, which provides a complete solution for private and hybrid clouds, and enterprise PaaS. "We are looking forward to upgrading to version 1.6.1 and taking advantage of the new features that will enable us to provide a more scalable and robust cloud computing environment for our global customer base."

Multi-Cluster Support, Enhanced Scaling and Configuration

The latest release of Eucalyptus now features support for multiple clusters, enabling Eucalyptus users to manage compute, network, and storage resources across multiple distinct clusters. It is not uncommon for IT infrastructures to be organized as separate clusters of machines to segregate resources based on different user groups, to partition the resources across geographically distributed data centers, or to isolate machines within a datacenter in accordance with organizational, business, or security policies. The extension of Eucalyptus to support multiple clusters provides a new level of organizational flexibility for IT administrators, allowing them to view their entire IT infrastructure as a single Eucalyptus cloud.

In addition, Eucalyptus can now more easily scale up to meet the requirements of an expanding IT infrastructure. An IT administrator can now install different components of Eucalyptus on different physical machines, ensuring that Eucalyptus can leverage both the security and performance topologies present in the IT data center. Further, to support greater flexibility and ease of management Eucalyptus installation is also now faster, with an easy, more automated install process.


With an elastic cloud computing infrastructure such as Eucalyptus, deployed to encompass multiple clusters, it is important for users to have visibility into various aspects of what is happening within the cloud. The latest release of Eucalyptus makes available a variety of relevant information which can be used in open source tools like Nagios and Ganglia to provide cloud administrators with insights on various aspects of the cloud, as well as the status of specific Eucalyptus components.

Eucalyptus Enterprise Edition Available

In addition to developing and supporting the Eucalyptus open source software, Eucalyptus Systems provides Eucalyptus Enterprise Edition (Eucalyptus EE), a commercial version of its eponymous software designed to meet the needs of enterprise IT. With Eucalyptus EE, customers can implement an on-premise Eucalyptus cloud with industry-leading virtualization technologies, including vSphere®, ESX™ and ESXi™. The only private cloud today to support VMware vSphere, Eucalyptus EE provides a robust, affordable cloud computing solution that leverages customers' investments in VMware technologies. Eucalyptus EE also supports other hypervisors typically found in a data center, such as Xen and KVM, providing customers the flexibility to configure cloud solutions that best meet their infrastructure needs.

Eucalyptus runs on a wide range of popular Linux distributions, including Ubuntu, Red Hat Enterprise Linux, CentOS, SUSE Linux Enterprise Server, OpenSUSE and Debian. The latest release, Eucalyptus version 1.6.1, is available today for download at
