Spot Instances for AWS

Create Autoscaling Groups (ASG) with Spot Instances in the DuploCloud platform

Spot Instances are spare capacity priced at a significant discount compared to On-Demand Instances. Users specify the maximum price (bid) they will pay per hour for a Spot Instance. The instance is launched if the current Spot price is below the user's bid. Since Spot Instances can be interrupted when spare capacity is unavailable, applications using Spot Instances must be fault-tolerant and able to handle interruptions.

Spot Instances are only supported for Auto-scaling Groups (ASG) with EKS
