The company's recently published Data Gravity Index report claims that Sydney will be the fourth fastest growth for data storage by 2024. It predicted that four of the six fastest growing cities for data storage would be in the Asia-Pacific region: Singapore (1st), Hong Kong (2nd), Sydney (4th) and Tokyo (6th).
Digital Realty pointed out that Australia was strategically located along submarine fibre cable routes, linking Sydney to Asia and said its new investment would complement its existing data centre in Western Sydney.
American consul-general Sharon Hudson-Dean said: "Digital Realty's continued investment in Australia, and Western Sydney specifically, is a welcome and positive development that builds upon the already strong business and investment ties between the United States and New South Wales, two critical partners for a prosperous future in the Indo-Pacific region."
Digital Realty chief executive A. William Stein added: "Sydney has always been a leading hub in developing and adapting to new data-led technologies, particularly through its position as a key economic centre within the Asia Pacific region. This acquisition represents a key milestone on our global roadmap for PlatformDIGITAL and will strengthen our ability to serve local and multinational enterprise customers in a key centre of data exchange."
The company's APAC managing director Mark Smith commented: "Big data, artificial intelligence, 5G mobile services and the Internet of Things are gaining momentum locally, with emerging technologies expected to contribute A$30 billion to Sydney's economy by 2029. The accelerating pace of digital transformation makes Sydney a key market for investment and the expansion of our global platform."
And Matt Berzak, vice-president of Portfolio Management, APAC for Digital Realty, said, "The expansion in Australia is an exciting new development, providing further evidence of Digital Realty's capabilities in the technology sector and in response to increased demand for digitisation from investors and enterprises.
"As the pandemic continues to drive more business around the world online, developing our PlatformDIGITAL® offering is crucial to supporting businesses through their digital transformation journey."
