Ability to add additional external IP addresses via Google Cloud interface to the Compute instance
Currently, Google VM instance can have only one external IP address.
It is required in the hosting industry. For example, to add additional dedicated IP for the website.

I think you can achieve this with multiple load balancers instead of giving the external IP to the instance.

Google, this is important for anyone who wishes to use GCP to offer website hosting via Plesk. Otherwise, all instances have no other option but to use shared IP addresses.
