Brings Open Source Cloud Computing to VMware Customers, a leader in open source private and public cloud computing software, today announced that its industry leading platform, CloudStack now supports VMware vSphere™ 4.1 and VMware vCenter™ Server. This new support enables enterprises and service providers who have already standardized on VMware virtualization technologies to extend their capabilities into the cloud without requiring changes to their existing infrastructure or virtualization management tools. will be demonstrating CloudStack on VMware vSphere at VMworld 2010, taking place August 30 – September 2 at the Moscone Center in San Francisco.

“We are pleased to see add support for VMware vSphere™,” said Jian Zhen, director, cloud computing solutions, VMware. “’s support underscores customer demand for developing cloud strategies on the industry’s only enterprise-class virtual infrastructure.’s customers can now choose to deploy their cloud infrastructure on the leading virtualization and cloud platform.” delivers all of the essential components used to build, deploy and manage multitier and multitenant cloud applications in a simple to install software package. CloudStack seamlessly integrates with existing data center infrastructure without modification, special-purpose hardware or reconfiguration, making it possible for customers to instantly realize the benefits of the cloud. Through the implementation of’s common cloud APIs, including planned support for VMware’s vCloud API, provides an open environment that interoperates with a user’s existing cloud initiatives, bringing interoperability and extensions to users’ existing cloud deployments.

“Since introducing CloudStack in May, we have seen incredible demand for our product on all hypervisors, so adding support for VMware vSphere and VMware vCenter allows us to support a large population of virtualization users with a diverse set of deployments and use cases,” said Sheng Liang, CEO and founder at “By supporting VMware vSphere, we are enabling customers to extend their virtualized environments to the cloud while enabling them to continue using tools that are already familiar to them. We expect this to greatly accelerate the time to market and the ROI that users experience with the cloud.”’s integration with VMware vSphere underscores its commitment to supporting a wide range of enterprise virtualization technologies to give’s users maximum flexibility and portability in architecting their cloud deployments.

“’s CloudStack combined with VMware vSphere enables us to build out reliable, elastic cloud computing solutions by using technologies that offer the best of both worlds – a leading open source cloud computing environment, running on the industry’s most advanced virtualization and cloud platform,” said Jason Baker, CTO at VISI. “With the addition of VMware vSphere as a supported platform for CloudStack, there is a significant reduction in complexity and risk to deploying a cloud service since we can do it with technologies and tools we already use.”


Founded in 2008 by leaders in open source, virtualization and infrastructure development, has pioneered a new approach to simplifying and accelerating the deployment, management and configuration of multi-tier and multi-tenant private and public cloud services. CloudStack is already deployed in production environments at leading enterprises and service providers, providing them with a new level of product stability and capability that is not found in solutions currently available in the market. is backed by leading Silicon Valley venture capital firms.
