Now that we’re seeing intense competition in the cloud infrastructure market, each of the vendors is looking for as many ways to differentiate itself as possible. Big wallets are required to build the infrastructure and picking the right locations to deploy that capital is becoming an important choice. Cloud vendors can be innovative on a product or technical level, but location is just as important — which geographies does your cloud vendor have data centers in and why does that matter?
Why is location important?
There are a number of reasons why a diverse range of locations is important:
- Redundancy: Compared to the chances of a server failure, whole data center outages are rare — but they can happen. In the case of power outages, software bugs or extreme weather, it’s important to be able to distribute your workloads across multiple, independent facilities. This is not just to get redundancy across data centers but also across geographies so you can avoid local issues like bad weather or electrical faults. You need data centers close enough to minimize latency but far enough to be separated by geography.
- Data protection: Different types of data have different locality requirements, e.g. requiring personal data to remain within the EU.
- User latency: response times for the end user are very important in certain applications, so having data centers close to your users is important, and the ability to send traffic to different regions helps simplify this. CDNs can be used for some content but connectivity is often required to the source too.
Deploying data centers around the world isn’t cheap, and this is the area where the big cloud providers have an advantage. It is not just a case of equipping and staffing data centers — much of the innovation is coming from how efficient those facilities are. Whether that means using the local geography to make data centers green, or building your own power systems, this all contributes to driving down prices, which can only truly be done at scale.
