• VPC peering
• Service Perimeter
• Cloud Router (~ vpc)
• Cloud Storage (~ S3)
• Compute Engine (~ ec2 )
• Cloud interconnect (~ direct connect )
• Persistent disk (Block storage service)
• Local SSD : (Ephemeral locally attached block storage)
• Firebase Hosting

Compute Engine:

For ssh access, best thing is to enable 'OS Login, check this link

• Best is to use linux from a 'public' image. They have the 'guest environment preinstalled.
• IAM-Admin > Manage resources . Select your project, add member, role 'Owner'. Or we can be more restrictive and add this roles by doing 'add role' and click in 'manage roles'
• Adding-ssh-keys : do it via the cloud shell (top right, command prompt symbol). The command is below (use double quotes to enclose the PubKey):

gcloud config set project <your-project-name>
gcloud compute os-login ssh-keys add --key='AAAsdfA..'

Shared VPC:

• We can have interconnects in different regions. GCP advertises prefixes via interconnects in different regions. So, if we lose all interconnects in one region, we, as a user can access gcp prefixes in that region via interconnects in other sides of the world.

TERRAFORM:
https://github.com/jotasantos/pubcloud/tree/main/gcp/tf_gcp
First install gcp sdk:

cd your-project
python3 -m venv env
source env/bin/activate
tar -xf google-cloud-sdk-352.0.0-linux-x86_64.tar.gz 
./google-cloud-sdk/install.sh    # exit the shell so the .bashrc changes take effect.
deactivate

Now authenticate your project and it will generate a json file that will be used in the tf provider:

gcloud auth application-default login --project <my-project-id-not-name>

Now we define the provider.tf (+ terraform init, terraform plan)

provider "google" {
credentials = "/home/myuser/.config/gcloud/application_default_credentials.json"
project = "my-project-id-not-name"
region = "us-east1"
}
