This is the third public release of the software stack and is thus targeted to the researchers and technology enthusiasts. It extends the functionalities of previous public releases.
The software was released on 16th April 2013.
What's new in the release?
- SLA Manager on the provider level,
- Virtual Infrastructure Network (VIN),
- Federation updates to reflect additional functionality (SLA and VIN support)
- Updates have been made to the security part as well, adding basic OAuth 2.0 functionality.
A Cloud administrator now can offer basic SLA functionalities at the provider level on top of the deployment of applications on a data center. Virtual networks are also possible with proper OVFs.
