Native, full-stack autoscaling on Upsun: PostgreSQL and MariaDB read replicas now autoscale

Upsun has launched a full-stack autoscaling feature for managed PostgreSQL and MariaDB read replicas, enhancing its platform's capability to dynamically adjust resources based on CPU and memory usage without requiring third-party database engines or a Kubernetes layer. This development, available to all Upsun customers as of July 2026, extends the existing autoscaling functionalities for applications and worker processes to managed databases, effectively eliminating the need for manual capacity adjustments that traditionally accompanied high-traffic events. By automatically scaling resources up or down in response to workload demands, Upsun's autoscaling system helps prevent database incidents during traffic spikes and optimizes resource utilization, thus reducing operational overhead and normalizing costs by aligning spend with actual usage.
