The website generates more than 100,000 unique visitors to its website each day addressing the flight needs of people in eight South East Asian regions, covering five languages.
The regions include Australia, New Zealand, Indonesia, Japan, Malaysia, Singapore, Thailand and Vietnam. The languages are English, Japanese, Chinese, Thai and Vietnamese.
Hostworks is a critical application management and hosting services company.
Klaus Bartosch sales and marketing director at Hostworks said the Jetstar contract demonstrated its 'strategic value for fast-growing businesses'.
"We are proud to support Jetstar's growth plans as it is one of the great Australian successes of the past few years," he said.
Jetstar's decision to outsource management of its Jetstar.com website is part of its growth strategy, which includes long-haul routes with orders for a number of Boeing 787 Dreamliners.
In line with its risk management strategy, Jetstar has its booking engine hosted by a separate service provider.
Jamie Perry general manager Distribution and Commercial Systems, Jetstar said the company selected Hostworks because of its specialist skills.
"As the business grows, this platform prepares us for growth in a structured and planned way," he said.
"Through the new Hostworks contract, we are in a virtualised environment.
"If we need more capacity than we currently have, virtualisation means it's a straightforward process to bring them on.
"Hostworks has the specialists on board to make it happen.
"We also have our mobile website hosted by Hostworks as mobile is a high growth area of the Internet."
