Amazon EC2 Spot Instances let you take advantage of unused Amazon EC2 capacity. 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. Starting today, you can assign Amazon Web Services resource tags to Spot Instance requests on creation, in addition to the tags for each individual, launched Spot Instances. Use tags in your Spot Instance requests to more easily identify their purpose. For example, you can use tags to identify all Spot Instance requests used by a particular department, project, or application.
You can use a single API call, Amazon SDK function, or Amazon CLI command to simultaneously create a Spot Instance request and specify its tags. Alternatively, you can also add, delete, or edit tags on Spot Instance requests after creation. You can even add tags to your existing Spot Instance requests today.
