Your Spot Instance runs until you stop or terminate it, or until Amazon EC2 interrupts it (known as a Spot Instance interruption). Amazon EC2 can stop, terminate, or hibernate a Spot Instance when it interrupts it. When you use Spot Instances, you must be prepared for interruptions.

To use Spot Instances, you create a Spot Instance request that includes the desired number of instances, the instance type, and the Availability Zone. If capacity is available, Amazon EC2 fulfills your request immediately.

June 30, 2025 - Use proactive capacity balancing: Capacity rebalancing helps maintain availability by adding a new Spot instance to the fleet before a running Spot instance receives the two-minute notification. It balances the capacity-optimized allocation strategy and the policy of mixed entities.
