Google Cloud – Multisite with or without Bitnami

Hi everyone,

I'm thinking about hosting a client's WP Multisite on Google Cloud. But they propose 2 options:

WordPress Multisite – estimated cost is $24.67/month

WordPress Multisite Certified by Bitnami – estimated cost is $14.20/month

I do not understand why the Bitnami version is cheaper and I don't even understand what's so special about the Bitnami version. I assume it is a pre-installed package which is monitored against treats and such… But I'm not sure.

Does anyone of you has experience with one of the versions or is anyone able to explain a bit more about this?

Much appreciated !
