Policy management in Amazon EKS using jsPolicy
Introduction jsPolicy is an open-source framework for managing validating or mutating admission control policies for Amazon Elastic Kubernetes Service (Amazon EKS) clusters using JavaScript (or TypeScript), which is similar to the way AWS Identity and Access Management (IAM) manages AWS accounts and resource access. It’s also possible to write the entire jsPolicy in a separate file and […]
Architecting for resiliency on AWS App Runner
AWS App Runner is one of the simplest ways to run your containerized web applications and APIs on AWS. App Runner abstracts away the cloud resources needed for running your web application or API, including load balancers, TLS certificates, auto-scaling, logs, metrics, tracing (such as observability), as well as the underlying compute resources. With App Runner, […]
Migrating and modernizing Windows Communication Foundation (WCF) workloads onto AWS container services
Introduction Windows Communication Foundation (WCF) is a framework created by Microsoft in 2008 for building service-oriented architecture (SOA) applications. It provides a set of libraries for building web services, using different network protocols to send and receive data between service endpoints. With the introduction of .NET Core in 2016 and the emergence of microservices, our […]
Leverage AWS secrets stores from EKS Fargate with External Secrets Operator
Secrets management is a challenging but critical aspect of running secure and dynamic containerized applications at scale. To support this need to securely distribute secrets to running applications, Kubernetes provides native functionality to manage secrets in the form of Kubernetes Secrets. However, many customers choose to centralize the management of secrets outside of their Kubernetes […]
Run an active-active multi-region Kubernetes application with AppMesh and EKS
NOTICE: October 04, 2024 – This post no longer reflects the best guidance for configuring a service mesh with Amazon EKS and its examples no longer work as shown. Please refer to newer content on Amazon VPC Lattice. ——— As application architects we have come across many customers who are moving towards a container-only strategy […]
Troubleshooting Amazon EKS API servers with Prometheus
It’s every on-call’s nightmare—awakened by a text at 3 a.m. from your alert system that says there’s a problem with the cluster. You need to quickly determine if the issue is with the Amazon EKS managed control plane or the new custom application you just rolled out last week. Even though you installed the default […]
Harden Amazon EKS in minutes with Styra DAS Free and OPA
In the Amazon EKS Best Practices Guide, AWS recommends Open Policy Agent (OPA) as a policy-as-code (PaC) solution for Kubernetes pod security. The long list of pros provided for PaC focuses mainly on the flexibility and comprehensive control that PaC provides when compared with built-in pod security admission. While PaC brings powerful flexibility, it can […]

Customizing scheduling on Amazon EKS
The interest in Kubernetes spiked in the fall of 2019, according to Google Trends. The US Department of Defense’s announcement that they had deployed Kubernetes on an F-16 could have attributed to the surge in interest. Today, Kubernetes is found in virtually every industry; from building Blockchain networks to 5G networks, customers use Kubernetes to […]
Using IAM database authentication with workloads running on Amazon EKS
Amazon Elastic Kubernetes Service (Amazon EKS) is a managed service that you can use to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control plane or nodes. When running containerized workloads on Amazon EKS, it is common to store the stateful parts of the application outside of the Kubernetes […]
