You can use the Amazon EC2 Instance to start, stop or reboot provisioned Amazon Elastic Compute Cloud (Amazon EC2) instances on demand, e.g. only when needed by the build itself (development) or at specific times of the day (operations).
Creating/Terminating instances
We currently consider instance lifecycle goals (i.e. create/terminate) to be sufficiently addressed by the AWS CloudFormation Stack task, hopefully covering the majority of use cases (please let us know otherwise).
