Google App Engine Vpn – Here is a step-by-step guide to building a multi-cloud architecture using GCP Cloud VPN and BGP dynamic routing.
Organizations are adopting hybrid and multi-cloud strategies to deliver best-in-class IT solutions, avoid being locked into a single cloud provider, or take advantage of cloud arbitrage.
Google App Engine Vpn
A VPN allows us to securely access resources residing in multiple clouds using their private IP addresses over the Internet. VPN forms encrypted tunnels between VPN endpoints using the IPSec protocol to secure the communication channel.
Creating A Site To Site Vpn Connection Between Gcp And Azure With Google Private Access
In this guide, we will use BGP (Border Gateway Protocol) dynamic routing, so that routes advertised by BGP from your client/peer’s gateway are automatically propagated to the routing table when the state of this connection Site-to-Site VPN is enabled . and established.
We will create the following components in the same order to establish end-to-end VPN connection between GCP and AWS:-
We should be able to see the external IP address assigned as in the following snippet (IP address intentionally blurred).
Here we need the external GCP IP we reserved in Step 1 to create the Customer Gateway. Use GCP’s reserved external IP as the client’s gateway IP.

Once the VPC is created, we can select that VPC and see the Details tab as shown in the following snippet.
Fill in the details of the gateway (use the external IP we reserved in step 1) and the VPC to share with AWS.
Once the tunnels are UP and established to AWS and GCP respectively, the VPN is up and can be used for private communication between the subnets associated with the VPN endpoints.

Another ideology you own won’t pay more than a quarter of that and the decades are already dead who cares what… As a local developer migrating to the cloud, you might think that the first step is to to start by moving data or virtual machines to the cloud. Actually, creating a VPC should be the foundation of your journey. A VPC stands for Virtual Private Cloud and is a private isolated virtual network partition that gives you managed network functionality for your Google Cloud Platform (GCP) resources. You can think of a VPC as a virtual version of your traditional physical network. It allows you to set up private communication between your virtual machines in the cloud, including routing and firewall rules so that you are protected from unwanted external access and limit the public exposure of your instances.
In a traditional VPC, scope is typically tied to a geographic region (such as US-West or US-East), and all communication between VMs in that region is expected to remain restricted. If you want to go further (connect workloads across regions), you will need private connectivity to ensure your workloads are not compromised (ie use a VPN connection on the public IPs of the regions). While this seems correct in theory, the overhead and cost associated with implementing it increases with each new region that needs to be added.
Google Cloud Brings Bare Metal Solution To New Regions
Imagine scaling to hundreds of projects with huge amounts of VPNs and VPN gateways to connect to. Additionally, you must add multiple routers in each VPC and use them through VPN tunnels to provide dynamic advertisements (BGP sessions) for your subnets, creating a variety of routers and BGP sessions that you manage. Although the tasks can be easily automated, network management can still include the responsibilities of coordinating policies that cross multiple management domains (organization, security, network, project, and endpoints).
This might be fine if your company needs complete isolation between virtual machines in different regions, but if you’re like most companies that want to spread their workloads across regions and reduce latency when traversing the public Internet, you’ll want those virtual machines can communicate. through a private network.
This is where the Google Cloud Global VPC comes into play. A single Google Cloud VPC can span multiple regions
It offers the same private ports for your local hardware, but also gives you global reach across regions, sharable configuration across your projects, and near real-time logging to monitor your application. It also comes with a full range of support services such as Shared VPC, Cloud Router, Firewall support, VPC peering and an industrial VPN.

The most impressive feature of GCP’s VPC system is that it allows your VMs to communicate across regions without needing the additional overhead VPNs to do so. All of this is done using the same global underlying network that powers Search, YouTube and Gmail. This means that Google handles your traffic under the hood by dynamically advertising routes through the VPC, and this is abstracted from the user.
But in case of a hybrid or migration scenario, it is important to plan your VPC and subnet ranges to avoid overlapping private IP ranges. This is the main reason why custom mode subnetting can be ideal on GCP.
Rest assured, you can rest easy knowing that on GCP you can quickly and easily extend your subnet’s IP ranges without interruption to your GCP services.
With that in mind, let’s take a quick tour of setting up a VPC for your existing on-premises setup using Google’s VPC.

If you prefer to create a VPC through a CLI, Google Cloud has a CLI-based SDK for shell scripts or interactive terminal sessions. You can create a VPC by
If you prefer not to use the CLI and are developing an application or prefer a programmatic approach, you can use one of the many client libraries that provide you with a wealth of functionality. You can even write directly to the REST API if you have specific needs. In addition to the above tools, if you need to build larger topologies on a regular cadence, you can visit Google Cloud Deployment Manager.
In the old world of networking, you used tangible building blocks like routers, switches, firewalls, cables, and racks. Assembling all the pieces to build interconnectivity between end users and applications took days and weeks. As the network grew, the associated management and costs of operating it also grew out of proportion.
Cloud networks handle this complexity and extract it from you by giving you managed software-defined networks. Google’s VPC, in particular, hides many of the complexities associated with the old building blocks. Even with increasingly complex networks and workloads, you can map your on-premises network topologies to Google Cloud with less administration and a host of tools. The next step in the migration journey is to set up a direct connection to the Google network. Stay tuned for the next piece.

In this lab, you will create two networks in separate regions and establish VPN tunnels between them so that a VM on one network can ping a VM on the other network by its internal IP.
Create two custom networks and an associated subnet as shown below. See How to Create Custom VPC Networks for detailed steps.
Getting To Know Google Compute Engine And How To Use It
You should be able to ping between VM instances through an external IP, but not through your internal IP.
Create the VPN ports and make all the necessary configurations to establish the VPN tunnels. Create two VPN gateways, one in each region. Then create forwarding rules for ESP, UDP:500 and UDP:4500 for each VPN port.
Configure VPN for Network 1 and reserve a static IP, then create forwarding rules. To create a VPN connection: Check
Next, create forwarding rules for the VPN gateway on Network 2 similar to the one you created for the VPN gateway on Network 1
Resolving Network Connectivity Issues Between Google Cloud Services
The external IP addresses you reserved for each VPN gateway should be used by the forwarding rules you created. To verify, go to VPC Network -> External IP Addresses
Keep in mind that VPNs can take a few minutes to connect to your peers. At this point the ports are connected and communicating. Network services provide connectivity between cloud-based virtual machines, on-premises servers, and other cloud services. Google Cloud treats networking as a global function that encompasses all of its services. GCP’s network is built on Google’s Andromeda architecture, which enables cloud administrators to create and use software-defined network elements such as firewalls, routing tables, and virtual machines.
