Automates EC2 Spot instance usage on existing AutoScaling groups to save up to 90% of AWS costs.
AutoSpotting is an open-source AWS cost optimization tool that automates the use of Spot instances for existing AutoScaling groups. It replaces on-demand EC2 instances with cheaper Spot instances, delivering significant cost savings while maintaining reliability through automated failback mechanisms. The tool requires minimal configuration and integrates seamlessly with AWS services like CloudFormation and Terraform.
AWS users and DevOps teams managing AutoScaling groups who want to reduce EC2 costs with minimal operational overhead. It is particularly valuable for organizations with large EC2 footprints seeking quick, scalable Spot adoption.
Developers choose AutoSpotting for its frictionless integration with existing AutoScaling setups, automated failover to on-demand instances, and cost savings of up to 90%. Unlike manual Spot management, it requires no launch configuration changes and uses safe, auditable open-source code hosted in your own AWS account.
Saves up to 90% of AWS EC2 costs by automating the use of spot instances on existing AutoScaling groups. Installs in minutes using CloudFormation or Terraform. Convenient to deploy at scale using StackSets. Uses tagging to avoid launch configuration changes. Automated spot termination handling. Reliable fallback to on-demand instances.

Enabled via simple tags like 'spot-enabled=true', allowing quick rollout at scale without modifying launch configurations or infrastructure, as highlighted in the minimal setup requirements.
Delivers 60-90% cost reductions by automatically replacing on-demand EC2 instances with cheaper Spot instances, leveraging AWS Spot pricing with minimal operational overhead.
Automatically falls back to on-demand instances during Spot capacity interruptions, ensuring high availability without manual intervention, as described in the failover features.
Uses a capacity-optimized-prioritized allocation strategy to select compatible Spot instance types, balancing low cost and reduced interruption rates without vendor lock-in.
Many advanced features like multi-region support, parallel instance replacement, and recent instance type coverage are only available in the Commercial Edition, as shown in the feature comparison table.
The Community Edition silently fails for AutoScaling groups using Mixed Instances Policy, which can lead to undetected operational issues and require manual workarounds.
Spot event handling defaults to Rebalancing Recommendation in the Community Edition, increasing instance churn compared to the optional Termination Notification in the Commercial Edition.
