20160070555 | AUTOMATED TENANT UPGRADES FOR MULTI-TENANT SERVICES - Automated tenant upgrades are provided for moving tenants in a multi-tenant service from a source scale unit to a target scale unit. Before real tenants are moved, test tenants are moved and the target scale unit health is monitored. Monitoring simulates user activity in the test tenants to look for problems with the target scale unit. If no significant problems are detected after moving the test tenants, real tenants are upgraded in batches. Target scale unit monitoring continues while real tenants are being upgraded and problems reported by real tenants already upgraded to the target scale unit are also considered when assessing the target scale unit health. If a significant problem occurs, tenant upgrades are paused until the issue is resolved. Automated tenant upgrades improve usability of a multi-tenant service by minimizing the service disruptions due to upgrade problems while providing cost effective upgrades to the latest builds. | 03-10-2016 |
