Through programming languages like Node.js / Python: See Turn on/off Cloud instances using AWS Lambda. The task running twice a day for typically less than 3 seconds with memory consumption up to 128MB typically costs less than $0.0004 USD/month

For Azure and Rackspace (or other platforms you may have):
Use the above tools to provide a Respective API to start/stop instances on demand.

You may also consider to set scripts-per-boot which runs each time your instance is started.
