Connect to Google Cloud Free for 90 Days with Digital Realty

This is the web view link from an email I received:

https://www.digitalrealty.com/connect-to-google-cloud-free-for-90-days-with-digital-realty

I have no idea whether this is a good deal or not. I'm just naively reacting to the "Free" marketspeak.

Hope it's helpful to someone.

¡Saludos!
