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.

AWS Hybrid architecture and Edge 2.0

One of our customers approached Aviatrix in search of a high-performance encryption solution for their on-premise data centers and AWS. They were impressed with Aviatrix’s features, including visibility, a dedicated data plane, high-throughput encryption, and Terraform capability. However, they also had sister business entities still using AWS TGW, and didn’t want to spend too much time trying to convince them to switch to Aviatrix. That’s when they turned to us for a hybrid architecture solution.

Migrate from Azure vNet hub and spoke architecture to Aviatrix Transit

As enterprises increasingly strive to simplify their Multi-Cloud Networking Management, Aviatrix’s MCNA (Multi-Cloud Networking Architecture) has emerged as a leading solution. The MCNA offers a standardized and flexible multi-cloud networking infrastructure that spans regions and clouds with ease. When combined with Aviatrix Edge, enterprises benefit from a dynamic and dedicated data plane, and a wealth of day-2 operational enhancements, including deep visibility, auditing, and troubleshooting capabilities. The standardized and intelligent networking helps bridge skill gaps and advanced security features provide an extra layer of protection to the network. It’s no wonder that so many organizations are turning to Aviatrix’s Multi-Cloud Transit architecture.

However, for organizations that have already deployed cloud networking solutions, the migration process can be perceived daunting, with the fear of risk and the possibility of wanting to revert back to their previous architecture.

In this blog post, I will guide you through the process of migrating from an Azure native vNet hub and spoke architecture to Aviatrix Transit. I will show you how to do so seamlessly and with minimal risk, ensuring a smooth transition to the advanced features and benefits of Aviatrix MCNA.

Express Route to Aviatrix Transit – Option 3

In the past blogs, we have reviewed two options to connect from on-premise to Aviatrix Transits:

  • Express Route to Aviatrix Transit – Option 1, where we build BGP over IPSec overlay towards Aviatrix transit. This solution have following constrains:
    • Each IPSec tunnel have 1.25G throughput limit
    • Azure only support IPSec, not GRE as tunneling protocol
    • On-premise device must be able to support BGP over IPSec, also it is manual process to build/maintain IPSec tunnels from on-premise device.
  • Express Route to Aviatrix Transit – Option 2, where we utilize Azure Route Server and some smart design to bridge the BGP between Aviatrix Transit, Azure Route Server and ExpressRoute Gateway, then towards on-premise device. This solution have fpllowing constrains:
    • ARS can only exchange up to 200 routes with ERGW
    • No end to end encryption between on-premsie towards Aviatrix Transit, only MACSec can be used between on-premise devices towards Microsoft Enterprise Edge router.
    • Additional architecture complexity/cost and lose operational visibility, also this solution is in Azure only, means you will end up with different architecture in different clouds.

For enterprises moving business critical applications to multi-cloud, needing point to point encryption without sacrificing the throughput, looking for unified solution that can provides enterprise level visibility, control, audibility, standardization and troubleshooting toolsets. Neither above two solution would be ideal. IPsec is industry standard utilized by all Cloud Service Providers, but how are we able to overcome it’s limitation of 1.25Gbps per tunnel?

Aviatrix’s winning formular solves these challenges with it’s patented technology called High Performance Encryption (HPE). It automatically builds multiple IPSec tunnels over either private connectivity such as express route, or over Internet. Aviatrix then combine these tunnels into a logical pipe, to achieve line rate of encryption up to 25Gbps per appliance.

Aviatrix have several products supports HPE from edge locations: CloudN (Physical form factor), Edge 1.0 and Edge 2.0 (Virtual and physical form factor). They can be deployed on-premise data center, co-location, branch offices or retail locations. These edge devices enable customer enterprise grade visibility and control, monitoring and auditing and troubleshooting capability, as well as providing unified architecture for all major Cloud Service Providers. These solutions enable us easily push all the goodies Aviatrix Transit and Spoke architecture from the clouds towards on-premise.

In this blog, we will focus on how CloudN is deployed and connect to Aviatrix Transit. Here below is the architecture diagram:
