İMMİB: high availability with a zero data loss target
High availability with a zero data loss target for exporters’ associations using SQL Server Always On.
- 01
Problem
The SQL Server carrying the export registration systems ran on a single server; maintenance windows and hardware failures caused transaction outages.
- 02
Solution
Synchronous replication, automatic failover and read load distributed to the secondary copy with a SQL Server Always On Availability Group.
- 03
Result
Planned maintenance now runs without downtime; failover within seconds in a failure scenario, zero data loss.
- 04
Ongoing
Database management under Sentinel managed services; a monthly performance report.
