Database Isolation: How We Fight a Hundred Direct DB Connections
summary
The talk describes Solidgate’s migration from many services making hundreds of direct database connections to a service-based data access model. It covers stages of the transition, the bottlenecks encountered (connection scaling, operational overhead), how isolation changed infrastructure maintenance, and honest lessons about what worked and what didn’t.
