Just about when it felt like OpenStack has conquered the Infrastructure As A Service arena, Apache has just about reminded with this release that CloudStack is not lost in translation. The 6 month incubation comes with more than a dozen features, bug fixes, security fixes and fully audited codebase as per ASF guidelines.
When CloudStack was a Citrix baby, it was predominantly built to support Amazon EC2 API's unlike OpenStack which has created its own set of API's. However this release bundles all such support to Amazon AWS API's into a bundle that can be activated/deactivated as per users choice. The default option though is switched off.
The new release comes with Inter VLAN Routing (VPC), a capability to route network traffic between VLANs enabling communication between multi tier applications deployed on different VLANs. Other useful features includes introduction of "Tags" that can be associated to cloud resources for resource categorization and tracking. CloudStack 4.0.0-incubating now supports using a CAStor cluster as the back-end storage system for a CloudStack S3 front-end, and also supports Nicira NVP Plugin to support connectivity service. A detailed release notes can be found on Apache Incubator website for CloudStack.
For those interested, the Apache 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.
