Harness Cluster Orchestrator for Amazon EKS, a feature within the Harness Cloud Cost Management (CCM) module, empowers engineering, DevOps, and CloudOps teams to efficiently manage EKS clusters by providing workload-driven intelligent autoscaling, cost visibility, and automated optimization. By leveraging AWS Spot Instances and the distributed Spot orchestration capability, users can achieve up to 90% savings on cloud costs. The tool offers a simplified approach to workload and node resizing, ensuring that clusters are not over-provisioned, and provides options to balance Spot and On-Demand nodes for critical workloads. Harness, recognized as part of the AWS Service Ready Program for Amazon EC2 Spot instances, supports best practices and API integration for successful management of Spot instances. The Cluster Orchestrator also offers comprehensive features including workload distribution strategies, cost visibility down to an hourly level, anomaly detection, and workload resizing recommendations to optimize resource use and reduce expenses.
