Telstra has bought a stake in a San Francisco-based company whose software powers more than half of the world's busiest websites.
The strategic investment in NGINX is the 27th deal by Telstra Ventures - which invests in breakthrough companies that are strategically important to the telecom and technology company - since 2013.
No financial details were disclosed on Thursday, but typically Telstra Ventures spends between $5 million to $10 million on strategic investments.
Telstra Ventures managing director Mark Sherman said the investment was "driven by the company's strong market growth as well as its growing technology leadership in the application delivery and deployment market".
"When you look under the hood of many of the most popular websites around the world today you find NGINX's technology. This business continues to grow their share of the web server market and has compelling value-add propositions to sell," Mr Sherman said in a statement on Thursday.
