Stopping and starting EC2 instance to save money - drawbacks?
Because Amazon charges for their instances based on running hours, it's tempting to simply start the instance when you need it, then start the Wowza service, stream your content and then simply stop the instance when the show is over. Then next time you need to stream you just repeat that.
We might only stream five one-hour events a week and so for us, applying this strategy, will mean much lower cost than having the instance always running.
Now, are there any drawbacks to this? And would you recommend having the instance always running instead?
Are you using an EBS backed instance and stopping/starting it? The S3 backed instances which only allow you to start then terminate, not stop and start again, are the ones that need a startup package. The EBS backed instances can be stopped and started again and will still be configured as they were when stopped.
