Data centre equipment in Australia is a $2.5 billion a year business, but it ain't the business it once was. Growing demand for cloud rather than building your own data centre means that we're seeing a decline in building activity, especially for larger centres.
Gartner sums up the situation in its annual roundup of data centre expenditure:
Despite this spending increase, the number of data centres in Australia continues to decline as Australian businesses are focused on improving data centre economics, coupled with agility and management. Of the 62,314 data centres in Australia in 2015, only 11 are classified as large data centres, defined by Gartner as having at least 1,000 racks of equipment and/or at least 20,000 square feet, while 78 are enterprise data centres with at least 250 racks of equipment and/or at least 5,000 square feet. The vast majority are classed as single deployments or small racks in "computer rooms" in smaller companies.
One point to note there? Despite the widespread availability of cloud computing, there are still thousands of on-premises centres. We're not entirely ready to go all-cloud just yet.
