Lightsail Load Balancer with Plesk Ubuntu Wordpress Instances

Hi,

From all the documentation I've seen, AWS suggests that Lightsail Wordpress Highly Available and Scalable sites be set up with Wordpress Bitnami Instances.

Can Plesk Instances be used in this kind of setup? Is there any documentation to help show how to integrate Plesk Ubuntu instances with a Lightsail Load Balancer? (plus the other resources...Lightsail managed/RDS database, Cloudfront, etc.)

Or is it not recommended to do so?

Thanks!

David
