AWS Cloud Watch alarm triggering multi-metric auto-scaling

Question

I want to create a cloud browsing alarm clock that starts autoscaling based on more than one metric information. Since it is not supported by Cloud Watch (correct me if I am wrong). I was wondering how to overcome this.

Can we get data from different indicators, for example, CPUUtilization, NetworkIn, NetworkOut, and then create custom indicators using mon-put-data and enter this data to create a new metric based on how to initiate autoscaling?

Yes .. Cloudwatch simulators can only run on one Cloudwatch metric, so you will need to publish your own “aggregate” metric and alarms, as you yourself suggest.

Here is a blog post describing the use of custom metrics to run autoscale.
