Icehouse release overview


Published on

We welcome the newest version of OpenStack - Icehouse - and set an #OSATH user group meeting to talk more on this.
What's new in OpenStack
In this session we are going to review all OpenStack features and emphasize on the recent developments added during the last development cycle.
Following the 6-months release cycle, OpenStack releases the Icehouse version, which brings many new features and bug fixes.
Some of the issues to discuss are:
• compute hosts upgrade is better managed
• network configuration enhancements
• storage configuration and management changes
• Database as a Service (Trove) integration
Finally, we shall discuss what is being expected in the next development cycle, Juno.
