This blog was updated by Irene Garcia Lopez, Solutions Architect, and Mehdi Yosofie, Solutions Architect, in April 2024 to reflect Karpenter beta changes. Overview Karpenter is a dynamic, high performance, open-source cluster autoscaling solution for the Kubernetes platform introduced at re:Invent 2021. Customers choose an autoscaling solution for a number of reasons, including improving the […]

Video encoding and transcoding are critical workloads for media and entertainment companies. Delivering high-quality video content to viewers across devices and networks needs efficient and scalable encoding infrastructure. As video resolutions continue to increase to 4K and 8K, GPU acceleration is essential to real-time encoding workflows where parallel encoding tasks are necessary. Although encoding on […]

This post is co-written with Suraj Nair, Sr. DevOps Engineer at Grover. Introduction Grover is a Berlin based global leader in technology rentals, enabling people and empowering businesses to subscribe to tech products monthly instead of buying them. As a pioneer in the circular economy, Grover’s business model of renting out and refurbishing tech products results […]

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 […]

Introduction Karpenter is a Kubernetes node lifecycle manager created by AWS, initially released in 2021 with the goal of minimizing cluster node configurations. Over the past year, it has seen tremendous growth, reaching over 4900 stars on GitHub and merged code from more than 200 contributors. It is in the process of being donated to […]

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 […]

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 […]
