Feed: Recent Announcements. You can now resolve the private Kubernetes API server endpoint of your Amazon Elastic Kubernetes Service (EKS) cluster in AWS GovCloud (US) regions. This allows you to easily connect to an EKS cluster that is only accessible within a VPC, including when using AWS services such as AWS Direct Connect and VPC peering. When only the private endpoint is enabled, Amazon EKS automatically advertises the private IP addresses of the private endpoint from the public endpoint. Clients (such as the kubectl CLI tool) use the public endpoint as a DNS resolver to connect to the private endpoint ... Read More

Feed: AWS Big Data Blog. Amazon EMR is a cloud big data platform for running large-scale distributed data processing jobs, interactive SQL queries, and machine learning (ML) applications using open-source analytics frameworks such as Apache Spark, Apache Hive, and Presto. Amazon EMR supports Kerberos for authentication; you can enable Kerberos on Amazon EMR and put the cluster in a private subnet to maximize security. To access the cluster, the best practice is to use a Network Load Balancer (NLB) to expose only specific ports, which are access-controlled via security groups. By default, the NLB prevents Kerberos ticket authentication to any ... Read More
