You have your cloud running. Now it’s time to upgrade. How to do this with minimal customer impact? At Symantec, we are upgrading our platform every 6 months in order to keep up with OpenStack release schedule. During our last upgrade, we went from Havana to Icehouse with zero downtime on the data plane and a mere 10-minute downtime on the control plane. How? We want to share our experiences and approach.
In this talk, we will present our design and approach taken during this upgrade including:
Preparation, Testing and validation
Rollback plans
Minimizing impact on users
Timing, Orchestration and Automation during the upgrade
Operational efficiency
Service by Service upgrade strategy
