Compute Engine
f1-micro only has 0.6gb RAM. So we'll need to allocate a swap file, just in case we ran out of memory. Use the commands below.
1. sudo fallocate -l 1G /swapfile
2. sudo chmod 600 /swapfile
3. sudo mkswap /swapfile
4. sudo swapon /swapfile
5. echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
Even if there is already plenty of RAM available, it's still beneficial to have swap [source]

The Compute Engine stores the disk data independently of the instance. A persistent disk's life cycle is not tied to a particular instance, making them flexible and easily migrated. Persistent disks are also encrypted, and data is encrypted the moment it leaves the instance. [source]

GCE static IP pricing | Note: Starting January 1st, 2020, GCP will introduce an additional charge for publicly addressed VM instances that don't fall under the Free Tier. You will not be charged for other publicly addressed resources, such as forwarding rules. | “Each month, eligible use of all of your f1-micro instances and associated external IP addresses are free until you have used a number of hours equal to the total hours in the current month” https://cloud.google.com/free/docs/gcp-free-tier
