AWS Lambda increases network bandwidth for functions outside VPC

infraawsengineeraws-lambda
feature

AWS Lambda now supports scalable network bandwidth, increasing data transfer speeds for functions outside a VPC. This feature scales from 625 Mbps at 2GB of memory up to 3,000 Mbps at 10GB, benefiting latency-sensitive workloads processing large data volumes. To enable this, customers must request an increase via AWS Service Quotas. The enhancement is available at no additional charge in all commercial AWS Regions.

Features (1) ›
  • Scalable network bandwidth for Lambda functions outside VPC

    AWS Lambda now offers network bandwidth that scales proportionally with function memory for environments outside of a VPC. Bandwidth ranges from 625 Mbps at 2 GB of memory up to 3,000 Mbps at 10 GB.

Enhancements (1) ›
  • Improved performance for latency-sensitive workloads

    This update helps reduce function execution times and per-invocation costs by increasing network throughput for data-intensive processing. It addresses previous limitations of a 625 Mbps cap, enabling faster data transfer for large volumes of data.

Notes (2) ›
  • Enabling scalable network bandwidth

    To activate scalable network bandwidth, customers need to submit a request through AWS Service Quotas for the 'Network bandwidth per execution environment' quota. Once enabled, bandwidth scales automatically based on memory configuration for functions outside a VPC.

  • Availability and cost

    Scalable network bandwidth for functions outside a VPC is available at no additional charge in all commercial AWS Regions. Further details can be found on the Lambda quotas page.
