Google Cloud Platform (GCP) Free Tier conditions (https://cloud.google.com/free/docs/gcp-free-tier) say that "30 GB-months HDD" is included with a f1-micro VM instance.
But when you create an instance, you can choose a "standard persistent disk" or "SSD persistent disk".
My question is, does the "30 GB-months HDD" include "SSD persistent disk" or only "standard persistent disk"?
Thanks.
According to Google Cloud Platform documentation: "Standard persistent disks are backed by standard hard disk drives (HDD). SSD persistent disks are backed by solid-state drives (SSD)."
So, to be in the Free Tier you should choose a "Standard Persistent disk" when creating your VM instance.
For future reference, here you can find the performance (IOPS and Maximum sustained throughput) differences between these two types of persistent disks.
With Free Tier you can't use SSD persistent disks but if you signup with Free trial account you get $300 as mentioned here.
With this amount of credit you can use any resources you want. Once the the free credit is consumed, you will have to make a subscription to continue using deployed resources or to create new ones on GCP.
