The much anticipated release of the "Folsom" version of OpenStack, with new networking and block storage features, as well as the reintroduction of Hyper-V support, is a major step forward for the open source cloud platform.
The "Folsom" release has more than 185 new features and enhancements developed by more than 350 open source developers.
"Since Essex has been released in April 2012, we can see that many new features are coming thanks to developers. The biggest one is for sure that Quantum is now a core project and Virtual Networking is rapidly approaching," wrote Emilien Macchi, one French OpenStack enthusiast who worked as an intern at StackOps. ""Volume service has now its own separated project : Cinder."
Kevin Jackson, an OpenStack author and Infrastructure Architect, had this to say about Folsom:
"It’s hard to talk about OpenStack Folsom without mentioning two notable new projects: Quantum and Cinder. Quantum provides a feature-rich and extensible API for programmatically defining networks. This allows for far richer network topologies to be defined than currently available such as configuring multi-tier applications and the subnets they’re allocated. It also allows for more advanced configurations at the backend by utilizing plugins, such as utilizing the excellent Open vSwitch software or implementing QoS and security functions. Quantum gives users of OpenStack the ability to completely control all aspects of their cloud compute environment, without compromising the underlying infrastructure and security of the underlying OpenStack environment; Quantum brings true multi-tenancy without any restrictions of VLANs.
Cinder is the OpenStack Block Storage project that was formerly known as nova-volume. This re-birth into its own project allows this crucial piece of core functionality to be developed independently of Nova (Compute) itself. To a user, this means faster development, quicker bug fixes and newer features to meet the demands of today’s hosting requirements.
Other notable features included in Folsom are Microsoft’s hypervisor, Hyper-V, making a comeback."
This is the sixth release of OpenStack in its two-plus year history. The recently launched OpenStack Foundation is gearing up for another release in six months, currently code named Grizzly.
The key devlopers on the Grizzly project come from Rackspace, SwiftStack, Nebula, VMware-owned Nicira, SolidFire and Red Hat.
