Data center locations

You might think that “location” in the world of “the cloud” seems a bit oxymoronic, right? Unfortunately, this is one of the side-effects of marketers pushing “the cloud” as some amorphic mystery, where all of your resources are multi-homed rather than living in a single place. Some services abstract away the idea of “location” to allow your resources to live in multiple places simultaneously, but for many services (such as Compute Engine) resources live in a single place. This means that you’ll likely want to choose one nearby to your customers. For example, if your customers are based in Romania it would be best to look at a service like M247 International Colo to provide the hosting. Over in the UK as well, cloud servers and providers are becoming more and more popular – take EBC Group for example – they are often said to be if not one of, the best data centre birmingham – and maybe even the UK – has to offer.

Those looking to leverage features like colocation, high-speed connectivity, and total security may want to look towards flexible, reliable, and bespoke cloud services that can facilitate the hosting of your business’s servers – 4D Data Centres provides a safe and comprehensive solution for those in the market for this.

To choose the right place, you first need to look at the choices; let’s get right to it. As of this writing, Google Cloud operates data centers in four different regions around the world: two in the United States, one in Europe, and one in Asia.

This might not seem like a lot, but keep in mind that each city has many different data centers to choose from. By this measure, there are thirteen different physical places where your resources can exist.

How does this stack up to other cloud providers, as well as traditional hosting providers? Let’s take a look:

Table 2. Data center offerings by provider

Looking at these numbers, it seems that Google Cloud brings up the rear compared to the other cloud service providers. That said, there are typically two reasons why you might choose a provider based on data center locations offered, and both are focused on network latency:

  1. You need ultra-low latency between your servers and your customers. An example is high-frequency trading where you typically need to host services only microseconds away from a stock exchange, because responding even one millisecond slower than your competitors means you could lose out on a trade.
  2. You have customers who are far from the nearest data center. A common example is businesses in Australia (where neither Google nor Digital Ocean offer data center locations), and the nearest options (Taiwan or Singapore, respectively) are still far away. This means that even something as simple as loading a web page from Australia can be frustratingly slow.

Of course, there are many Advantages of Data Centre usage so the location isn’t always important. If your requirements are less strict, the location of data centers shouldn’t make too much of a difference in choosing a cloud provider, but it’s still important to understand your latency requirements and what geographical location means for that.
