AWS Autoscaling by SQS queues fast with no autoscaling policy using Lambda

Lambda python based over autoscaling lambda

To use this function, activate by triggering a CloudWatch event. The function will check by pairs SQS queue that you want an autoscale group to scale up.

pairs = [{'queue_name': 'sqs_q1', 'autoscale_group': 'autoscale_group1'},
         {'queue_name': 'sqs_q2', 'autoscale_group': 'autoscale_group2'}]

When new SQS count >= Auto scale desired Count it will set a new desired count for the autoscale group

It will consider the MaxSize of the auto scale group as the max size regardless the amount of messages in the queue
