It is hard to deny that Google has grown considerably ever since it burst onto the scene in the latter stages of the 20th Century. After all, it has gone from being just a search engine to offering widely-used services and products such as YouTube and Google Mail, in addition to one of the world’s most popular mobile operating systems in the form of Android. So, it’s safe to say that Google’s products have taken the world by storm over the last couple of decades.

Upon the introduction of the Google Cloud Platform in 2008, the tech giant began to provide a collection of their computing resources – making them available as a public cloud offering which the general public could make full use of. By 2017, Google had made 22 zones and 8 news regions available, which extended the original offering of 18 zones in 6 regions. This included Oregon, Iowa, Belgium, Taiwan, Tokyo, and South Carolina.

One of the most popular services provided by Google Cloud Platform is undoubtedly the Google Cloud VPN service – allowing you to connect the network on your premises to your Google Cloud Platform Virtual Private Cloud (VPC) network. This makes use of a secure IPsec VPN tunneling protocol which encrypts traffic traveling between the two networks by one gateway, then it is decrypted by the other VPN gateway.

In the following article, we’ll delve deeper into what Google Cloud VPN is all about and how it can help to secure private networks and any data that is transferred over the network. So, without any further ado, let’s get to it!

What is Google Cloud VPN and what does it do?

Before we jump into how Google Cloud VPN works, it would be appropriate to explain exactly what it is first, right?! Well, it is essentially a service which allows you to connect your existing infrastructure to the widely-used Google Cloud Platform, otherwise known as GCP.

Using the same infrastructure that is used for end-user products including YouTube and Google Search, Google Cloud Platform has gone from strength to strength in that it allows its user base to benefit from over 50 services. Not only does this include the Google Cloud VPN, but it also includes such things as Storage and Databases, Networking and Identity, Management and Developer tools, and so much more.

Each feature of the Google Cloud Platform can be used individually or even in combination. So, if you’re looking to make use of the Google Cloud VPN service in conjunction with another of the services, you have the ability to do exactly that if you so desire.

This is something that you would do if you were to connect using a device such as a computer or a tablet device.

The whole set up process should be relatively plain and simple for anyone who is an expert when it comes to setting up VPN connections. To get things up and running, you will need to run through your settings on the Google Cloud Platform web interface. Once you have done exactly that, you will be able to connect your existing infrastructure to the secure Google Cloud Platform over the internet – taking full advantage of the authenticated and encrypted connection which keeps your personal information and data secure at all times.

However, just remember that while site-to-site VPN is supported with an SLA of 99% service availability, you will need a dedicated physical or virtual VPN gateway on the client side. So, be sure to bear this in mind before you attempt to get everything set up.

    Am I wrong for thinking this is similar to letting the fox guard the henhouse? I don’t see people who value their privacy entrusting any secure data to Google. My understanding is they work with governments to spy on people. Please correct me if I’m wrong, but I use my VPN to protect myself from Google so why would I use the Google Cloud VPN?

      I feel the same way. Google already knows too much about all of us so why give it even more power? It’s clear that intentionally or unintentionally (being hacked), the data Google stores can be at risk at any time.
