# Cloud Provider Limitations ## Spot Instance Interruptions By nature, EC2 SPOT instances are cheaper because they can be taken back by AWS anytime. [Refer to the official AWS Documentation for more information.](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-interruptions.html) Due to the unpredictable nature of interruptions, e6data Clusters may not function correctly. Therefore, Spot instances are recommended only for non-critical workloads. The following can occur depending on which e6data component was interrupted: * Query execution failures * Autoscaling failures * Catalog creation & modification failures --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
