We are excited to announce that Amazon EMR on EKS now supports vertical autoscaling, a feature to automatically tune the memory and CPU resources of EMR Spark Applications to adapt to the needs of the provided workload, offering a simplified mechanism for customers to tune resources, enhance reliability and optimize costs. Amazon EMR on EKS enables customers to run open-source big data frameworks such as Apache Spark on Amazon EKS without having to manage application provisioning themselves.
