Oracle Autonomous Database Auto-Scaling: A DBA's Guide to Elastic Performance

Oracle Autonomous Database auto-scaling automatically adjusts CPU and storage resources based on workload demands, eliminating manual scaling decisions. The feature scales CPU up to 3x baseline capacity during sustained 80 %+ utilization and increases storage automatically at 85% capacity. Implementation requires enabling the feature via OCI CLI, establishing baseline metrics, and configuring proper monitoring. Real-world benefits include 30-50% cost reduction and 99.9% availability during peak periods. Best suited for unpredictable workloads in e-commerce, financial services, and healthcare. Avoid sub-100ms SLA requirements or predictable batch workloads. Key success factors: baseline establishment, comprehensive monitoring, phased deployment, and SQL optimization before scaling.
