Introduction Sustainable cloud design requires understanding and minimizing the impacts of architectural decisions. With conscientious cloud architecture, we can innovate rapidly while treading lightly on our shared environment. As cloud computing becomes ubiquitous, it’s imperative that we build sustainable cloud architectures that minimize environmental impacts. While cloud economies of scale improve efficiency, our design choices […]

In the evolving cloud-native landscape, enterprises utilizing Amazon Elastic Kubernetes Service (Amazon EKS) often encounter challenges that hinder their pursuit of operational efficiency and cost-effectiveness. Notable among these challenges are the costs associated with Cross Availability Zone (AZ) traffic, with difficulties associated with achieving seamless scalability, hurdles in provisioning right-sized instances for nodes, and intricacies […]

In today’s cloud-native landscape, efficient management of event-driven workloads is essential for real-time data processing. Traditional autoscaling often falls short amidst unpredictable event volumes, leading to inefficiencies and increased costs. Amazon Elastic Kubernetes Service (EKS), which is a managed container orchestration platform and is well-suited for deploying container-based applications. By integrating Kubernetes Event-Driven Autoscaling (KEDA) […]

Introduction Karpenter is an open-source, high-performance Kubernetes cluster autoscaler that automatically provisions new nodes in response to unschedulable pods. Customers choose Karpenter for many reasons, such as improving the efficiency and cost of running workloads in their clusters. Karpenter works by configuring a custom resource called Provisioner. This Provisioner sets constraints on the nodes that […]

March 2024: This blog has been updated for Karpenter version v0.33.1 and v1beta1 specification. 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 […]

[May, 2024 – This blog has been updated to reflect Karpenter v1beta1 API changes] 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 […]
