  "account": "For startups weighing the option of using EKS (Elastic Kubernetes Service) or k3s on AWS, the decision hinges on factors like cost, complexity, and the size of the team. The article advises that if you are an indie builder or a 1 to 2 person team testing out Kubernetes, running k3s on a single EC2 box is recommended. This approach avoids the $73/month control plane fee associated with EKS and allows for quick setup in under a minute.\n\nIf you are a small team of up to 20 engineers without a dedicated platform owner, starting with k3s is also advised. Focus on shipping the product first, and decide later whether to graduate to EKS. For teams of 20+ engineers dealing with production traffic, multi-AZ requirements, or strict compliance needs, EKS is the better choice. The controlled environment and AWS-native autoscaling features like IRSA (Identity and Access Management roles for service accounts) and autoscaling pay off at this scale.\n\nThe article highlights that both EKS and k3s are Kubernetes, meaning they share the same API and manifests. The key difference lies in who owns the control plane and the level of AWS infrastructure management required. EKS entrusts AWS with the control plane, requiring additional glue components like IRSA, VPC CNI, and autoscalers. In contrast, k3s runs the control plane on an EC2 instance, making upgrades and management faster and easier. Network management, ingress, storage, and upgrade processes also differ significantly between the two.\n\nA practical example comparing costs shows that running k3s on EC2 can handle around 8 vCPU/16GB of production pods plus staging environments for less than $400/month, accommodating 5-10 services, including staging and previews. On the other hand, EKS incurs a higher monthly cost (~$410-$440), primarily due to the control plane fee, additional nodes, and the complexities of VPC CNI and ingress controllers. The article also emphasizes the hidden costs of setup and management, such as engineer days required for initial setup, upgrades, and troubleshooting issues like IP exhaustion and ALB controller version pinning. Conversely, k3s setup is considerably faster (under a day) and requires less operational overhead, with tasks like updating the AMI and nightly etcd snapshots handling the maintenance.",
  "summary": "You have an app to ship. Maybe a few. You're on AWS because that's where the credits are and where the auditors want your data. Somebody on the team said \"Kubernetes\" out loud and now you're trying to decide between EKS and k3s before the week is out. We'll save you the essay. Here's our take: If you're an indie builder or a 1 to 2 person team just trying the product out , run k3s on a single EC2…",
