The Apache CloudStack project is pleased to announce the 4.0.0-incubating release of the CloudStack Infrastructure-as-a-Service (IaaS) cloud orchestration platform. This is the first release from within the Apache Incubator, the entry path into the Apache Software Foundation (ASF).

Apache CloudStack is an integrated software platform that allows users to build a feature-rich IaaS. CloudStack includes an intuitive user interface and rich API for managing the compute, networking, accounting, and storage for private, hybrid, or public clouds. The project entered the Apache Incubator in April 2012.

The 4.0.0-incubating release represents the culmination of more than six months work by the CloudStack community. The release includes more than a dozen new features, many bugfixes, security fixes, and a fully audited codebase that complies with ASF guidelines.

New Features:

  • Inter-VLAN Routing (VPC)
  • Site-to-Site VPN
  • Local Storage Support for Data Volumes
  • Virtual Resource Tagging
  • Secure Console Access on XenServer
  • Added the ability to create a VM without immediately starting it (via API)
  • Upload an Existing Volume to a Virtual Machine
  • Dedicated High-Availability Hosts
  • Support for Amazon Web Services API (formerly a separate package)
  • AWS API Extensions to include Tagging
  • Support for Nicira NVP (L2)
  • Ceph RBD Support for KVM
  • Support for Caringo as Secondary Storage
  • KVM Hypervisor support upgraded to work with Ubuntu 12.04 and RHEL 6.3

In addition to the official source code release, individual contributors have also made convenience binaries available on the Apache CloudStack download page.

CloudStack Collaboration Conference

The CloudStack project will have its first collaboration conference in Las Vegas, from November 30th through December 2nd at The Venetian. The conference will provide an opportunity for the community to learn more about CloudStack, share best practices for deploying CloudStack, and discuss ideas for upcoming releases.

Apache CloudStack is an effort undergoing incubation at The Apache Software Foundation (ASF). Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

The CloudStack Collaboration Conference schedule is now up! You can find it at:

A big thank you to everyone who's submitted talks, and to David Nalley, Chip Childers, and John Kinsella for helping wade through the submissions. We were initially concerned about the quantity of submissions given the short run-up to the conference - but we were blown away by the quality *and* quantity of the submissions.

We'll be announcing keynotes shortly, and the evening events. A lot of really good stuff coming for the conference - I hope to see many of you there, you really don't want to miss it!
