I'm one of the maintainers of the cloud images and I can confirm that our goal is to release at least GCP and Azure images in addition to the AWS ones for the 3.14 release cycle. We're also looking for suggestions on other cloud providers for which people would like to see official Alpine images built.
It is hoped that the cloud images project will get Alpine available in all of the main platforms, we've done AWS already starting with 3.13.
