Harness Cluster Orchestrator Launched
December 05, 2022

Harness announced Harness Cluster Orchestrator to allow customers to optimize their Kubernetes cloud workload costs and realize up to 90% cloud cost savings with Amazon Elastic Compute Cloud (Amazon EC2) Spot instances from Amazon Web Services (AWS).

A fully managed feature of Harness Cloud Cost Management (CCM), Harness Cluster Orchestrator brings advanced automation to orchestrate Amazon EC2 Spot instances for Amazon Elastic Kubernetes Service (Amazon EKS) workloads, so enterprises can ensure application uptime at the lowest cost, without any manual engineering intervention.

Harness also announced it has joined the AWS Service Ready Program for Amazon EC2 Spot instances. This designation recognizes that Harness CCM with Cluster Orchestrator implements best practices and API support to successfully manage Amazon EC2 Spot instances in customers' cloud environments. Joining the Amazon EC2 Spot Service Ready Program differentiates Harness as an AWS Partner Network (APN) member with a product that works with Amazon EC2 Spot instances and is generally available for and fully supports AWS customers, helping them benefit from Amazon EC2 Spot savings for their workloads.

Amazon EC2 provides a variety of instance purchase options that enable customers to optimize costs based on their workload needs. Spot instances use spare EC2 capacity that is available for less than the On-Demand price. Because Spot instances enable customers to request unused EC2 instances at steep discounts, customers can lower their Amazon EC2 costs significantly. Additionally, Spot instances are a cost-effective choice for customers that can be flexible about when their applications run and if their applications can be interrupted. For example, Spot instances are well-suited for data analysis, batch jobs, background processing, and optional tasks.

Harness Cluster Orchestrator delivers fully automated Amazon EC2 Spot instance orchestration and automation, following AWS best practices, allowing customers to save up to 90% on their cloud costs. Harness Cluster Orchestrator closes the gap on compute availability guarantees to increase Amazon EC2 Spot instance deployment across production workloads and proactively manages cluster resources, so engineers do not have to manually do so. When receiving an Amazon EC2 Spot instance interruption notice from AWS, Harness Cluster Orchestrator automatically provisions an alternate Amazon EC2 Spot instance that has available capacity, enough resources to run the pods, and the least likelihood of future interruptions. Harness Cluster Orchestrator temporarily switches from Spot to On-Demand when Amazon EC2 Spot instance capacity is unavailable to maintain availability and avoid running under-capacity. During this fallback from Amazon EC2 Spot to On-Demand, the Harness Cluster Orchestrator continuously monitors for available Amazon EC2 Spot capacity and when it finds available capacity, does a reverse fallback to Amazon EC2 Spot. This process is fully automated, with no manual intervention required.
