Does AWS charge for lambda in sleep state

Question

For instance:

count = 0
        while True:
            try:
                if count == 5:
                    break
                snap = ec.create_snapshot(
                    VolumeId=vol_id,
                    Description=instance['InstanceId']
                )
                break
            except Exception as e:
                print(e)
                sleep(180)
                count = count + 1

So If I have lot of instances and errors then it could be long time of running lambda. What could be alternative to put Lambda to sleep?

Answer 1

Yes you are still charged. Calling sleep() does not stop the execution environment. You pay for the duration of the execution environment, from the time the function is invoked until the time the function finishes executing (or until it reaches the configured timeout).

Answer 2

My assumption is yes they do. AWS Lambda charges based on three factors

1. Allocated memory to function
2. Number of Executions
3. Compute duration

If you look at the definition of how duration is calculated.

Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 100ms. The price depends on the amount of memory you allocate to your function. You are charged $0.00001667 for every GB-second used.

AWS calculates charges from the time your code begins executing, to the point at which it returns/terminates.
