Spot Instances

Spot Instances are a type of AWS EC2 instance that allows you to take advantage of unused capacity in the AWS cloud at a significantly reduced cost. Spot Instances are available at a discount of up to 90% compared to On-Demand Instances, however, they are subject to interruption if AWS needs the capacity back for other purposes. This makes Spot Instances ideal for workloads that can tolerate interruption, such as batch processing, data analysis, and web servers.

Spot Instances are a great option for a variety of use cases, including:

• Batch processing: Spot Instances are ideal for batch processing jobs that can be interrupted without losing data. For example, you could use Spot Instances to process a large dataset or to run a series of simulations.
• Data analysis: Spot Instances can be used for data analysis tasks that can be interrupted without losing data. For example, you could use Spot Instances to analyze a large dataset or to train a machine learning model.
