Previously limited to IPv4 connectivity, Amazon EMR Serverless now supports running Apache Spark and Hive workloads over IPv6 and dual-stack subnets within an Amazon VPC. This enhancement provides flexible connectivity options, allowing workloads to access IPv4 and IPv6 endpoints seamlessly while maintaining backward compatibility with existing IPv4 applications.

Addressing IPv4 address exhaustion and emerging regulations mandating IPv6, this update enables gradual IPv6 adoption. Operational in all AWS Regions offering EMR Serverless, these connectivity options are available at no extra charge and compatible across all EMR Serverless release versions.
