Amazon EC2 Spot Instances

Run fault-tolerant workloads for up to 90% off

Amazon EC2 Spot Instances let you take advantage of unused EC2 capacity in the Amazon Web Services cloud. Spot Instances are available at up to a 90% discount compared to On-Demand prices. You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, CI/CD, web servers, high-performance computing (HPC), and other test & development workloads. Because Spot Instances are tightly integrated with Amazon Web Services services such as Auto Scaling, EMR, ECS, CloudFormation, Data Pipeline and Amazon Batch, you can choose how to launch and maintain your applications running on Spot Instances.

Moreover, you can easily combine Spot Instances with On-Demand and RIs to further optimize workload cost with performance. Due to the operating scale of Amazon Web services, Spot Instances can offer the scale and cost savings to run hyper-scale workloads. Only on Amazon Web Services, you have easy access to unused compute capacity at such massive scale - all at up to a 90% discount.


Low, Predictable Prices

You can purchase Spot Instances at prices up to 90% lower than On-Demand instances. Moreover, you can provision capacity across Spot, On-Demand, and RIs using EC2 Auto Scaling to optimize workload cost with performance.

Scale Your Application

Spot Instances offer you the advantages of the massive operating scale of Amazon Web Services. You can run hyperscale workloads at a significant cost savings or you can accelerate your workloads by running parallel tasks. Learn more »

Easy to Use

Spot Instances are easy to launch. Add a single parameter to the same API used to launch OD instances - instances will be launched immediately as long as capacity is available. Learn more »

How it works

Step 1: Before running Spot instances, refer to using Spot instances.

Step 2: Choose all instances and Availability Zones that work for your workloads.

Step 3: Select your interruption behavior (Stop/Terminate).

Step 4: Launch and Scale your target capacity.

Use Cases

Spot Instances are well suited to a variety of workloads. The more distributed, scalable, and fault tolerant your application, the easier it is to save money and increase throughput.
