AutoSpotting Reviews & Product Details

AutoSpotting allows you to safely and reliably cut your AWS EC2 costs by up to 90% (usually 50-80%) without long term commitments or upfront payments, by replacing EC2 instances in autoscaling groups with identically configured Spot instances. It installs in minutes using CloudFormation and Terraform, and can be configured using tags and even taking over all the groups from your account, without requiring launch template or launch configuration changes, and without causing IaC drift. For maximum compatibility, it supports most applications backed by on-demand autoscaling groups, including for AWS services such as Beanstalk, EKS and ECS that use ASGs under the hood. The main requirement is for the instances to be replaceable without noticeable impact to your users, which is usually the case for autoscaling groups out of the box. For maximum security, privacy and reduced runtime costs it is a fully self-hosted, serverless, pay as you go software that runs entirely in your account with minimalist IAM permissions. Once enabled on your on-demand ASGs by tagging them(you can use any tool for tagging, but we also have a GUI to make it easier and reduce the chance of human errors), it gradually replaces their instances with diversified Spot instances. Under the hood we use attach API calls, then terminate the initial instances, leaving you with up to 90% cheaper but identically configured Spot instances. To minimize capacity churn as much as possible, any new instances are also replaced with the same approach within seconds of being launched, and we use a capacity optimized allocation strategy that gives us instances with lower probability of interruption. To ensure you always get the capacity you need for your application, Spot instances are launched with widest possible diversification, and we also have failover to on-demand instances with the same level of diversification we use for Spot instances. This makes the groups managed by AutoSpotting more resilient to Insufficient Capacity Events that may occasionally impact OnDemand ASGs usually configured with a single instance type. For increased performance and reduced carbon emissions, it always provisions the newest available instance types.
