Introduction Cluster autoscaler, has been the de facto industry standard autoscaling mechanism on kubernetes since the very early version of the platform. However, with the evolving complexity and number of containerized workloads, our customers running on Amazon Elastic Kubernetes Service (Amazon EKS) started to ask for a more flexible way to allocate compute resources to […]

Introduction Amazon VPC Lattice is a fully managed application networking service built directly into the AWS network infrastructure that you use to connect, secure, and monitor all of your services across multiple accounts and virtual private clouds (VPCs). With Amazon Elastic Kubernetes Service (Amazon EKS), customers can use Amazon VPC Lattice through the use of […]

Introduction When the margin for error is razor thin, it is best to assume that anything that can go wrong will go wrong. AWS customers are increasingly building resilient workloads that continue to operate while tolerating faults in systems. When customers build mission-critical applications on AWS, they have to make sure that every piece in […]

Introduction WebSocket is a common communication protocol used in web applications to facilitate real-time bi-directional data exchange between client and server. However, when the server has to maintain a direct connection with the client, it can limit the server’s ability to scale down when there are long-running clients. This scale down can occur when nodes […]

Introduction AWS Fargate is a serverless compute engine for running Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Elastic Container Service (Amazon ECS) workloads without managing the underlying infrastructure. AWS Fargate makes it easy to provision and scale secure, isolated, and right-sized compute capacity for containerized applications. As a result, teams are increasingly choosing AWS […]

About a year ago, we published a post on how to Optimize your Spring Boot application for AWS Fargate, where we went into different optimization techniques to speed up the startup time of Spring Boot applications for AWS Fargate. We started the post with “Fast startup times are key to quickly react to disruptions and […]

Introduction Karpenter is an open-source cluster autoscaler that provisions right-sized nodes in response to unschedulable pods based on aggregated CPU, memory, volume requests, and other Kubernetes scheduling constraints (e.g., affinities and pod topology spread constraints), which simplifies infrastructure management. When using Cluster Autoscaler as an alternative autoscaler, all Kubernetes nodes in a node group must […]

Introduction Today, we’re announcing the preview of Amazon Elastic Kubernetes Service (EKS) extended support for Kubernetes versions. You can now run Amazon EKS clusters on a Kubernetes version for up to 26 months from the time the version is generally available on Amazon EKS. Extended Support is available as a free preview for all Amazon […]

Introduction In the ever-changing landscape of cloud computing, organizations continue to face the challenge of effectively managing their virtual network environments. To address this challenge, many organizations have embraced shared Amazon virtual private clouds (VPCs) as a means to streamline network administration, and reduce costs. Shared VPCs not only provide these advantages but also enable […]

Introduction In this post, we’ll explore how to publish and consume services running on Amazon Elastic Container Service (Amazon ECS) and AWS Lambda, as Amazon VPC Lattice services. For an introduction to Amazon VPC Lattice, please read the documentation here. One main reason customer experience a lower velocity of innovation, is the complexity they deal […]
