More Reliable, More Resilient, More Redundant: High Availability Update for Grizzly and Beyond
Speaker: Florian Haas, hastexo
OpenStack high availability has seen a lot of progress since it was defined as an overarching design goal during the Folsom cycle. Not only is there now a reference architecture for highly available OpenStack infrastructure services, but OpenStack is also gradually growing native high availability features. In this session, we are giving an overview of the current state of high availability technology in OpenStack, and an outlook as we enter the Havana cycle.
In particular, this session covers:
– OpenStack infrastructure high availability with the Pacemaker stack
– The status of high availability in OpenStack AMQP messaging and database access
High Availability features in OpenStack Compute (Nova):
– Automatic node evacuation, to address physical compute node failures
– The status of automatic Nova guest recovery
– Ensembles (virtual machine groups) to deploy multi-guest applications resilient to physical node failure
High availability improvements in OpenStack Networking (Quantum)
Attendees should have a good general understanding of OpenStack components. High availability experience is a plus, but not required.
