Is there any service in AWS which would start and stop the instance at particular time?

I have an EC2 instance and I want to stop at 12:00 am at night and start it again at 7pm everyday.Is there any AWS service by which I could achieve this?

Any help would be appreciated

My recommendation would be to use AWS Instance Scheduler. There is a demo video at https://aws.amazon.com/premiumsupport/knowledge-center/stop-start-instance-scheduler/

You can do that using Two approach, Two lambda functions or you do that using one but for that, you may need to check trigger time and second is bash script using AWS CLI with cron job.

Using Lambda:

  1. Lambda function to stop instance at 12:00 AM
  2. Lambda function to start instance at 7 PM

Important thing both Lambda should be based on scheduled event. Remember that the time is in UTC.

enter image description here

1.To Stop

region = 'us-west-1'
instances = ['i-12345cb6de4f78g9h', 'i-08ce9b2d7eccf6d26']

def lambda_handler(event, context):
    ec2 = boto3.client('ec2', region_name=region)
    ec2.stop_instances(InstanceIds=instances)
    print 'stopped your instances: ' + str(instances)
  1. To start
import boto3
region = 'us-west-1'
instances = ['i-12345cb6de4f78g9h', 'i-08ce9b2d7eccf6d26']

def lambda_handler(event, context):
    ec2 = boto3.client('ec2', region_name=region)
    ec2.start_instances(InstanceIds=instances)
    print 'started your instances: ' + str(instances)

Lamda role

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:CreateLogGroup",
        "logs:CreateLogStream",
        "logs:PutLogEvents"
      ],
      "Resource": "arn:aws:logs:*:*:*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "ec2:Start*",
        "ec2:Stop*"
      ],
      "Resource": "*"
    }
  ]
}

You can read more details about this approach here and here.

Using AWS cli and Cron Job

stop.sh

#!/bin/bash
ID="i-1234567890abcdef0"
echo "stop instance having ID=$ID
aws ec2 stop-instances --instance-ids $ID

start.sh

#!/bin/bash
echo "starting instance....."
aws ec2 start-instances --instance-ids i-1234567890abcdef0

cron job

To stop

0 0 * * * stop.sh To start

0 7 * * * start.sh

Using the second approach you will be saving resources and cost of Lamda function.

There are a few different ways to do this.

  1. Create an ASG with timed scaling events. Scale to 0 instances at 12:00 AM and 1 instance at 7:00 PM. That's super easy!
  2. Use CloudCustodian and create a custodian policy.
  3. Use the reference arch here: https://aws.amazon.com/solutions/instance-scheduler/

There are enough examples on this, you can follow the official links of aws for doing this.

If you are looking for a simple solution I would suggest doing it using AWS lambda and cloudwatch https://aws.amazon.com/premiumsupport/knowledge-center/start-stop-lambda-cloudwatch/

If you are looking for a robust solution, then as mentioned in earlier doc follow https://aws.amazon.com/premiumsupport/knowledge-center/stop-start-instance-scheduler/
