AWS Lambda announces new capabilities to optimize costs up to 90% for Provisioned mode for Kafka ESM

This article announces new cost optimization capabilities for AWS Lambda's Provisioned mode for Kafka event source mappings (ESMs), enabling up to 90% cost reduction.

• ESM grouping allows multiple Kafka ESMs to share Event Poller Unit (EPU) capacity within same VPC
• Default event pollers per EPU increased from 4 to 10 for low-throughput use cases
• Improved EPU utilization reduces costs up to 90% for low-throughput workloads
• Maintains Provisioned mode benefits: throughput controls, schema validation, filtering, low-latency invocations
• Available in all AWS Commercial Regions where Lambda Provisioned mode for Kafka ESM operates
• Configuration via Lambda ESM API, Console, CLI, SDK, CloudFormation, and SAM using PollerGroupName parameter

These enhancements make Provisioned mode cost-effective for all Kafka workloads, including lower-throughput applications, while preserving performance and control features.
