Eucalyptus Supports VMware Hypervisor

Eucalyptus Systems has been noted so far for its ability to supply open source code interfaces that match those of Amazon (NSDQ: AMZN)'s Web services. Open source Eucalyptus code can be used to build an internal cloud that is compatible with Amazon's EC2. The company has announced it will support VMware's ESX
hypervisor and vSphere 4 virtual machine infrastructure as the
foundation for a private cloud.

The move marks the young company's first foray into a commercial product, Eucalyptus Enterprise Edition, which is aimed at allowing VMware customers to leverage their extensive investment in VMware products to build a private cloud.

"This is a first step on the roadmap to let data centers integrate whatever virtualization technology they are most comfortable with," said Rich Wolski, Eucalyptus CTO, in an interview during VMworld. He is on leave from the University of California at Santa Barbara where he lead the Eucalyptus open source project as a computer science professor. The project built interfaces that mimic the basic functions of Amazon's EC2 public cloud, such as loading workloads as virtual machine images, generating long term S3 storage, and short term Elastic Storage Blocks storage.

The Eucalyptus version of those interfaces can be used to build private clouds inside the enterprise capable of running virtual machines governed by the open source Xen or KVM hypervisors. VMware's ESX Server is the first commercial environment Eucalyptus has chosen to support. It's also stopped short of trying to duplicate Amazon's SimpleDB, since MySQL is commonly used in the open source projects and environments where Eucalyptus got its start.

Private clouds are typically described as cluster-type computers in the data center available 24 hours a day through an easily accessible interface, for those authorized to use them. The private cloud can deliver elastic resources, which expand or contract, depending on the needs of the workload sent to them. Users are charged by time elapsed, not the capital expense of setting up the cloud. Clouds are built to run virtual machines and are typically managed through a virtualized environment's management console.
