Data centres assist businesses by allowing them to outsource computing power and/or digital data storage.
Data centres are generally classifieds in one of the following categories:
Data centre REITs typically build centres in key network locations, provide infrastructure for drawing power and cooling, then lease space or “racks” to customers wanting a reliable location to store and use their information infrastructure. Customers will pay a recurring fee for the rack and pay for their own power use, power usage is typically a pass-through cost for the Data Centre REIT.
Another key increasingly important revenue driver for data centres is the ability to charge tenants for interconnection. Interconnection in its simplest form is to connect two different customers within the data centre infrastructure whether the connection is physical or a software solution. This allows the two tenants to access each other’s servers without using a “public” connection such as a telecommunication provider allowing for faster and more reliable connection. Data Centres will charge an on-going interconnection fee for this. The importance of scale is highlighted in interconnection as larger data centres are able to interconnect more tenants globally.
Generally, the more developed a data centre market is, the more interconnection revenue is derived from it.
Capital costs to build data centres are high further highlighting the importance of scale. Unlike another commercial real estate where the land is the largest cost, land typically comprises just 5-10% of the total build cost of a data centre. Fitouts, electrical systems, air conditioning play a much larger role in the cost structure of a build.
Barriers to entry is also high with certification of uptime a key requirement to attract tenants. Data centres are expected to run without failure and very little maintenance. The Uptime Institute is the global standard for grading data cente uptimes, their requirements are as follows:
Customers can generally be broken into two types, wholesale and retail.
Wholesale tenants generate fewer sales per unit of capacity, require larger power output, but will generally have long lease terms and are an important selling point to all other customers. Customers such as Amazon Web Services (AWS) Microsoft (Azure), Google Cloud also interconnect with other tenants ensuring low latency for all tenants. Although not a perfect analogy, large wholesale customers can be seen as the anchor tenants which drive other data traffic as an anchor supermarket would in a shopping centre.
Retail customers such as small to medium enterprises, startups generate better unit economics and require less power but have shorter terms and are considered a lower quality credit.
As one would expect, the growth of data centre revenue is directly related to the amount of data that needs to be stored and accessed globally. Colocation services is expected to grow at mid to high single digits, whilst interconnection revenue is expected to grow at low double digits CAGR in the medium term.

Data Centres are becoming more relevant and important in a deeply digitally penetrated world, however they are not immune to risks such as:
Data centres are a key infrastructure enabler of the information technology age. It is an attractive industry with structural tailwinds as data usage, access and storage continue to grow. Data Centre REITs are an attractive way to gain exposure to this thematic with solid economics. As the market grows organically at 5-10%, additional services such as interconnection will serve as high margin incremental income with relatively low current penetration.
