Unable to delete GCP VPC, already being used by networkInstances

When tried to delete GCP VPC following error occurs:

jye@cloudshell:~ (<gcp-project>)$ gcloud compute networks delete cloud-sql
The following networks will be deleted:
 - [cloud-sql]

Do you want to continue (Y/n)?  y

ERROR: (gcloud.compute.networks.delete) Could not fetch resource:
 - The network resource 'projects/<gcp-project>/global/networks/cloud-sql' is already being used by 'projects/<gcp-project>/global/networkInstances/v-1171710760-6bcedd6c-b842-4dd0-9e64-65c2ef70f480'

Found out previously I had tried to enable App Engine access Cloud SQL privately by using Serverless VPC Connector

Then in App Engine app.yaml, following statement was used to tell App Engine to use the connector

vpc_access_connector:
  name: "projects/<gcp-project>/locations/us-central1/connectors/cloud-mysql"

This has resulting the App Engine to create a network interface with the VPC specified

Since you cannot purge App Engine, I have deployed another app that doesn’t require connection to the VPC: 

git clone https://github.com/GoogleCloudPlatform/python-docs-samples
cd python-docs-samples/appengine/standard_python3/building-an-app/building-an-app-1
gcloud app deploy

Now that the App Engine is no longer bind with the VPC

Make sure to delete the Serverless VPC connector

In App Engine, make sure to purge versions that uses the Serverless VPC connector.

Then try to delete the VPC again

gcloud compute networks delete cloud-sql
The following networks will be deleted:
 - [cloud-sql]

Do you want to continue (Y/n)?  y

Deleted [https://www.googleapis.com/compute/v1/projects/jye-01/global/networks/cloud-sql].

Success!

Aviatrix High Performance Encryption (pseudo) with 3rd party devices

Aviatrix Gateways – Spoke, Transit, CloudN, and Edge – offer a simple and efficient way to establish highly available and high-performing data planes. With the Aviatrix Controller, multiple encrypted tunnels can be automatically created, ensuring seamless redundancy and fast throughput. By deploying a pair of gateways at each end, Aviatrix builds four full mesh tunnels, creating a reliable data path with up to 5Gbps of throughput. But what makes Aviatrix truly stand out is its patented High Performance Encryption, which leverages multiple IP addresses and CPU cores to create multiple IPSec tunnels. This unique approach can achieve up to 70Gbps throughput, delivering exceptional performance.

However, not all customers are ready to implement CloudN or Edge. For these situations, Aviatrix still provides encryption and the ability to create multiple IPSec tunnels for higher throughput. In this blog post, we will delve into how to achieve this and explore the benefits of using Aviatrix Gateways for highly available and high-performing data planes.
