If you have a choice, we recommend storing your servers and data in two external data centers instead of one. In this blog, we explain why using multiple data centers make sense.
Collocating your server park and associated storage capacity is all about guaranteed uptime and limiting the risks. Using two external data centers in different locations – which are, of course, linked together by high-speed networks – is an option that provides maximum redundancy and allows you to mitigate additional risks.
Physically split data and processes
With geographically split data centers, your data and processes are physically split. This is very important when data is stored in one of the data centers or when there’s difficulty in accessing data. Two data center deployment can be done in various ways and configurations. For example, one data center can be used for data backup. But it is also possible to run both environments in parallel. This way, you never lose data and your business-critical applications will always be up and accessible.
Guidelines for geographical distance
In the banking world, for example, there are guidelines for the required geographical distance between a primary and secondary external data center. A distance of at least 30 km is recommended. Latency, i.e. the time it takes for data to get to its destination across the network, is another important factor that should be taken into consideration if you plan to make use of two data centers. The enormous exchange of data between both data centers will also increase the cost. So it’s important to find the appropriate balance between security and budget.
