Amazon EMR on EKS Gets IPv6 Support for Massive Analytics Workloads
AWS just dropped IPv6 support for Amazon EMR on EKS, meaning you can now run massive Spark and Flink jobs on IPv6 clusters without IPv4 address headaches. Scale your analytics workloads across all AWS Regions with virtually unlimited address space—no more CIDR range workarounds needed, and it costs nothing extra starting with EMR 7.14.0.
