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 simplifies the creation and the deployment of HPC clusters. AWS API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. In this post we combine AWS ParallelCluster and AWS API Gateway to allow an HTTP interaction with the scheduler. […]

We are happy to announce that Open Distro for Elasticsearch 1.1.0 is now available for download! Version 1.1.0 includes the upstream open source versions of Elasticsearch 7.1.1, Kibana 7.1.1, and the latest updates for alerting, SQL, security, performance analyzer, and Kibana plugins, as well as the SQL JDBC driver. You can find details on enhancements, […]

Many Open Distro for Elasticsearch users manage data life cycle in their clusters by creating an index based on a standard time period, usually one index per day. This pattern has many advantages: ingest tools like Logstash support index rollover out of the box; defining a retention window is straightforward; and deleting old data is […]

Open Distro for Elasticsearch Security (Open Distro Security) comes with authentication and access control out of the box. Prior posts have discussed LDAP integration with Open Distro for Elasticsearch and JSON Web Token authentication with Open Distro for Elasticsearch. Security Assertion Markup Language 2.0 (SAML) is an open standard for exchanging identity and security information […]

Data is being gathered and created at rates unprecedented in history. Much of this data is intended to drive business outcomes but, according to the Harvard Business Review, “…on average, less than half of an organization’s structured data is actively used in making decisions…” The root of the problem is that data is typically spread […]

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 […]

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 […]

This post describes how to configure Gravitational’s Teleport as an authentication proxy for Amazon Elastic Kubernetes Service (Amazon EKS), using GitHub as the identity provider for authenticating users. In this example, Teleport is installed onto a stand-alone EC2 instance and configured to use GitHub authentication to authenticate users identities. Once authenticated, the role assigned to […]

When we launched Amazon EKS, we had a plan for a more complete command line. We were intrigued by Weaveworks’ simultaneous launch of the open source command line tool eksctl, and excited about the user feedback we were hearing. We decided, instead of building our own, to embrace eksctl as part of the EKS planning […]
