Distributed TensorFlow training using Kubeflow on Amazon EKS

Training heavy-weight deep neural networks (DNNs) on large datasets ranging from tens to hundreds of GBs often takes an unacceptably long time. Business imperatives force us to search for solutions that can reduce the training time from days to hours. Distributed data-parallel training of DNNs using multiple GPUs on multiple machines is often the right […]

Running secure workloads on EKS using Fairwinds Polaris

Getting configurations right, especially at scale, can be a challenging task in cloud-native land. Automation helps you to make that task more manageable. In this guest post from EJ Etherington, CTO for Fairwinds, we look at an open source tool that allows you to check your EKS cluster setup, providing you with a graphical overview […]

EKS support for the EBS CSI driver

Today, we are announcing EKS support for the EBS Container Storage Interface driver, an initiative to create unified storage interfaces between container orchestrators such as Kubernetes and storage vendors like AWS. A History of Storage in Kubernetes As originally conceived, containers were a great fit for stateless applications. However, there was no provision for persistent […]

Introducing fine-grained IAM roles for service accounts

Here at AWS we focus first and foremost on customer needs. In the context of access control in Amazon EKS, you asked in issue #23 of our public container roadmap for fine-grained IAM roles in EKS. To address this need, the community came up with a number of open source solutions, such as kube2iam, kiam, […]

Using a Network Load Balancer with the NGINX Ingress Controller on Amazon EKS

Kubernetes Ingress is an API object that provides a collection of routing rules that govern how external/internal users access Kubernetes services running in a cluster. An ingress controller is responsible for reading the ingress resource information and processing it appropriately. As there are different ingress controllers that can do this job, it’s important to choose the right one for the type […]

AWS ParallelCluster with AWS Directory Services Authentication

AWS ParallelCluster simplifies the creation and deployment of HPC clusters. In this post we combine ParallelCluster with AWS Directory Services to create a multi-user, POSIX-compliant system with centralized authentication and automated home directory creation. To grant only the minimum permissions to the nodes in the cluster, no AD configuration parameters or permissions are stored directly […]

Best Practices for Running Ansys Fluent Using AWS ParallelCluster

Using HPC (high performance computing) to solve Computational Fluid Dynamics (CFD) challenges has become common practice. As the growth from HPC workstation to supercomputer has slowed over the last decade or two, compute clusters have increasingly taken the place of single, big SMP (shared memory processing) supercomputers, and have become the ‘new normal’. Another, more […]
