AWS has upgraded Amazon Aurora Serverless to respond faster to sudden workload spikes, including those generated by agentic AI applications. The database now adds up to 16 Aurora Capacity Units to its current capacity within one second and continues scaling up to 256 ACUs as demand increases.
When workloads finish, Aurora Serverless automatically scales down to zero, helping organizations avoid paying for unused capacity. The improvement targets applications with unpredictable traffic, short bursts of database activity and long idle periods.
Instant scaling is enabled by default for Aurora Serverless clusters running platform versions 3 and 4, requiring no configuration changes.
