Enter , two engineers who were tired of seeing startups burn through their funding on idle servers. They realized that the cloud providers (AWS, Azure, Google Cloud) had a secret inventory: Spot Instances .
| Aspect | AWS ASG | EC2 Fleet | Elastigroup | |--------|---------|-----------|--------------| | Spot fallback | Manual mixed policies | Yes | Fully automated | | Pre-termination hook | 2 min notice (you handle) | Same | Automatic drain + replace | | Stateful spot | No | Partial (volume reuse) | Yes (disk + network state) | | Cost savings | 60–70% (spot) | 60–70% | 70–90% via diversification | | Learning-based scaling | No | No | Yes | elastigroup
The technology became so robust that it could handle stateful workloads—databases and complex applications that were previously thought too fragile for the Spot Market. Enter , two engineers who were tired of
: For data-heavy tasks that require massive parallel processing, Elastigroup provides the scale needed at a fraction of the price. : For data-heavy tasks that require massive parallel
| Feature | Description | Benefit | |---------|-------------|---------| | | Chooses instance types with lowest historical interruption | Higher stability | | Fallback to on-demand | When spot market price > bid or capacity unavailable | 99.9% availability SLA | | Predictive scaling | Uses ML to scale before load arrives | Lower latency | | Stateful recovery | Retains ephemeral disk data across spot terminations | Stateless apps become stateful | | Integration | CloudFormation, Terraform, EKS, ECS, GKE, Datadog | Operational ease |
