In its latest 10-K filing, Amazon Web Services has revealed how much property it has control over - 26 million square foot (2,415,500 sq m).

That is broken down between 11.9 million sq ft (1,105,500 sq m) that it owns and 14.1 million sq ft (1,310,000 sq m) that it leases.

The filing does not disclose how much of that is actually data center white space, rather than all the other additional parts of data center, sales, and other property. However, it does not include corporate facilities or headquarters.

"Property and equipment acquired under finance leases was $11.6 billion and $7.1 billion in 2020 and 2021, reflecting investments in support of continued business growth primarily due to investments in technology infrastructure for AWS," the filing states.

Amazon operates 84 availability zones in 26 regions. It does not disclose the location of its data centers, nor which wholesale data center companies it partners with.

In 2018, WikiLeaks revealed the locations of Amazon's data center footprint from 2015.

At the time, the company operated some 38 facilities in Northern Virginia, eight in San Francisco, another eight in its hometown of Seattle and seven in northeastern Oregon. In Europe, it had seven data center buildings in Dublin, Ireland, four in Germany, and three in Luxembourg. Over in the APAC region, there were 12 facilities in Japan, nine in China, six in Singapore, and eight in Australia. It also housed infrastructure in six sites in Brazil.

It also disclosed that the company had partnerships with Equinix, CyrusOne, Digital Fortress, Hitachi, Terremark, KVH, KDDI, Keppel, Tata Communications, Colt, Global Switch, iseek-KDC, NextDC, and Ascenty (now owned by Digital Realty).

Since then, Amazon has only aggressively expanded its data center presence, building out facilities around the world and leasing space from wholesale companies.

Last year, it spent $32.5 million and $40m just to buy two plots of land in Northern Virginia, where it already operates around 40 data centers in Haymarket, Manassas, Ashburn, Chantilly, and McNair. It also plans to build on a 41-acre plot in Fauquier County and has filed an application to build four data centers on an empty plot of land in Manassas, Virginia.

That year, DCD discovered the company was behind a large data center in Oxfordshire, UK, and a smaller facility in Swindon - both of which it tried to keep secret. It is also trying to build up to four upcoming data centers in Clonshaugh, Dublin, and a data center design site in Croatia, to name but a few.

It has eight more regions, each made up of geographically independent zones, known to be on the way.

In the last financial quarter, AWS revenue hit $17.8 billion - up 39.5 percent year-over-year. Synergy Research Group estimates that the company controls about 32-33 percent of the global cloud market share, making it the undisputed largest provider.
