Reserved Instances are not really instances - they're a billing feature, giving you a lower hourly rate for any running instance that matches the availability zone and OS and instance type of the reservation. You still need to launch the instances and manage their lifecycles. You can boot from an EBS-backed AMI. EBS-backed instances can be "stopped" and "started", which allows you to keep them off but intact. The contents of disk are preserved while "stopped", and to the OS it looks like a power off (stopping it) and power on (restarting it). @Vivek Khurana,

Halting your machine will wipe it because machine is deleted when halted. Btw, Amazon reserved instances preserve data when you halt a machine.
