Scheduled Instances are a good choice for workloads that do not run continuously, but do run on a regular schedule. For example, you can use ScheduledInstances for an application that runs during business hours or for batch processing that runs at the end of the week.If you require a capacity reservation on a continuous basis, Reserved Instances might meet your needs and decrease costs.https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-scheduled-instances.html
