AWS introduced scalable network bandwidth for Lambda functions executing outside virtual private clouds (VPCs), with throughput increasing linearly from 625 Mbps at 2 GB memory allocation up to 3,000 Mbps at 10 GB. This upgrade addresses latency-sensitive, large-volume data processing workloads by providing faster external data access, potentially reducing invocation duration and associated costs. The feature requires service quota activation and is available at no extra charge across commercial AWS regions.
This network enhancement targets customers needing higher data transfer rates, enabling serverless functions to better handle growing data volumes without redesigning architectures. While AWS provided these bandwidth rates, independent real-world measurements assessing throughput gains or impact on latency were not included in the announcement.
