Lightweight, certified Kubernetes for IoT and edge computing environments

About k3s

K3s is a certified Kubernetes distribution designed specifically for production workloads in resource-constrained, remote, or unattended environments such as IoT devices and edge computing nodes. It simplifies Kubernetes deployment by packaging the entire system into a single binary under 70MB, reducing dependencies and installation complexity. This makes it ideal for organizations looking to extend cloud-native infrastructure to edge locations with limited resources.

The platform supports multiple architectures including ARM64 and ARMv7, enabling it to run efficiently on devices ranging from Raspberry Pi to large cloud servers. K3s is optimized for high availability and secure operation in environments where traditional Kubernetes distributions may be too heavy or complex. Its streamlined architecture and automated updates help enterprises manage distributed clusters with minimal operational overhead, making it suitable for industries deploying IoT solutions, edge computing, and CI pipelines on ARM-based hardware.

Backup & Disaster Recovery

Evaluate Veeam, Commvault, Rubrik, Cohesity, Dell PowerProtect, and Druva against your real RTO and RPO targets — with ransomware resilience, not backup windows, as the deciding criterion.

Cloud Cost Management & FinOps

Compare IBM Apptio Cloudability, VMware Tanzu CloudHealth (Broadcom), Flexera One, Harness, Finout, Zesty, and Vantage on the question this category actually turns on — not whether a dashboard is pretty, but whether shared-cost allocation is accurate, committed-use buying is optimized, and engineering acts on the recommendations.

Cloud Infrastructure & IaaS

Compare AWS, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure, IBM Cloud, Alibaba Cloud, and DigitalOcean on the one thing the pricing calculator hides — egress, support-tier costs, committed-use discounts, and lock-in — not the on-demand compute rate the demo shows you.
