Auto Shutdown and Start Amazon EC2 Instance?

I recommend you take a look at the EC2 Getting Started Guide which shows you how to do what you need using the EC2 command line tools. You can easily script this into a cron job (on Linux / UNIX) or scheduled job on Windows to call the start and stop commands at a given time.

If you want to do this from your own code, you can use the SOAP or REST APIs; see the Developer Guide for details.

You can try using the Amazon EC2 API tools directly. There are really only two commands you need: ec2-start-instances and ec2-stop-instances. Make sure that environment variables such as EC2_HOME, AWS_CREDENTIAL_FILE, EC2_CERT, EC2_PRIVATE_KEY, etc.Are properly configured and all AWS credentials, certificate and private key files are in proper location - you can find more info in the AWS EC2 API tools documentation.

You can test the command by hand first and then, when everything works fine, configure Unix crontab or Scheduled Tasks on Windows. You can find the example below for the Linux /etc/crontab file (do not forget that all those environment variables mentioned above need to be present for 'your-account' user. /etc/crontab 0 8 * * * your-account ec2-start-instances 0 16 * * * your-account ec2-stop-instances # Your instance will be started at 8am and shutdown at 4pm.

I am a developer for the BitNami Cloud project, where we package the AWS tools (including the ones I mentioned) in a free, easy to use installer that you may want to try: BitNami CloudTools pack stack.

You could look at Ylastic to do this. The alternative seems to be having one machine running that shuts down/starts other instances using a cron job or scheduled task. Obviously if you only want one instance this is an expensive solution, as one machine has to always be running, and paying ~$80 a month for one machine to run cron jobs isn't cost effective.

If it's not mission critical - A simplistic thing to do is to schedule batch file to run 'SHUTDOWN' (windows) at 3am every day. Then at least you don't run the risk of accidentally leaving an unwanted instance running indefinitely. Obviously this is only half the story!

You cannot do this automatically, or at least not without some programming and API manipulation in script files. If you want to a reliable solution to stop, restart and manage your images (presumably to control costs in your environment) then you may want to look at LabSlice.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
