Google has the largest private network in the world

Google is more than a search engine. It’s the mother of all clouds. Google Cloud has the largest privately-owned network in the world.
Over the past few years, the amount of data and traffic has increased dramatically. As Google handles about 25% of all internet traffic, Google invested $30 billion in infrastructure in the past 3 years. And because of the expected growth, we increased our investments this year with another $13 billion.

Google’s private network
This enormous increase in data usage translates into a need for increased performance. Using our own network, we have managed this increase by creating a more efficient network. As such, we can deliver faster and more reliable connectivity by developing direct paths between the cloud and end-users; with Google’s network there is no need to rely on other public networks. 

Clearly, our network is big with up to 60% of all internet connected devices communicating via our network daily, including game consoles and home media devices. In addition, Google owns or operates all subsea cables that we use, which allows us to play a big role in intercontinental communication. 

4.000 miles of private subsea cable
To improve services, we have recently started construction of our own private Trans-Atlantic subsea cable. Yes, that is Google’s own 4.000 mile long fiber optic cable. The cable will run on the bottom of the ocean from the US to France. Usually, most companies either use an existing cable or build one with a consortium. We did it on our own. This way, we can design a network that best suits our own customers.

We’ve built some shorter private Alpha, Beta and Curie cables. Recently, Google announced that it would name private cables after influential innovators in alphabetical order. As such, the newest cable is called Dunant, named after the first Nobel Peace Prize winner. Dunant is expected to be completed in late 2020. It will allow for even faster and better connectivity between Europe and the US.

Connectivity at the speed you need
Operating our own private network, we have the opportunity to fine-tune the performance that is provided to customers. For some user applications, faster connectivity is most important, whereas for other applications it’s cost. To address connectivity versus cost issues, Google introduced two options: Standard Tier and Premium Tier networks. Standard tier provides lower performance at a lower cost, and traffic travels over public clouds. While the downside is that some more congestion and outages can occur, traffic is still comparable to that of other leading public clouds. The Premium Tier option uses Google Cloud and guarantees the fastest connectivity.
