Colocation Services Sydney

When you think of colocation, you should definitely consider Sydney, Australia’s ICT and Digital Capital; and the ICT investment destination of choice in Australia.

Convenient Location for Colocation Services

The NTT ICT Sydney data centre is just outside of the major metropolitan CBD area, perfect for colocation and easily accessible by a range of transport options.

More colocation options for your business

NTT ICT colocation services come in a flexible range of power and cooling options to support anything from one rack unit devices to the most powerful blade server or storage enclosures. Optional additional services for colocation in the data centre include remote hands and feet, managed infrastructure and utility (cloud) services.

NTT ICT colocation facilities offer significant cost savings on connectivity – you can expect to save 20–40% on the cost of a circuit delivered to our data centre versus an office-based facility.

Our data centres are purpose-built for energy efficiency, and are typically 20–40% more efficient than office-based facilities. This is due to our efficient internal distribution systems, and our connection to the national grid via high voltage cable.

 The IT landscape in Sydney

Sydney is the IT hub of NSW which has an $18.6 billion information, media and telecommunications industry - the largest of any Australian state. Home to around half of Australia’s startup companies, Sydney is an innovation hotspot which has prompted breakthroughs, such as those when:

  • Google’s Sydney office developed Google Maps
  • The technology behind WiFi was developed in the CSIRO’s labs in NSW

In recent years Sydney has seen prominent global ICT companies such as Dropbox, LinkedIn and Expedia choose the city’s CBD as the location for major regional headquarters.

Sydney was found to be the most future ready economy in Australia and tenth in the world in an April 2016 study by Dell. Not only Australia’s biggest population centre, Sydney is home to 46.5% of Australia’s startup companies, making it an innovation hotspot. With over 178,000 ICT workers in NSW - more than any other state - ICT is flourishing in Sydney which boasts the best quality of living standards of any major Australian city, according to the Mercer 2016 Quality of Living survey.

 As the capital of NSW, Sydney is the financial capital of Australia and provides companies with ready access to funds and financial advice. Similarly, Sydney provides access to a sophisticated telecommunications infrastructure, blue ribbon office space and a large skilled and educated workforce.
