Application server software maker Citrix Systems has relocated its regional headquarters to Hong Kong from Sydney as part of its Asian expansion plans. The Hong Kong office will oversee operations in China, Taiwan, Hong Kong, South Korea, India, Singapore, the Philippines, Malaysia, Indonesia, Thailand and Vietnam. With a strong customer base already in Hong Kong, Dennis Rose, vice-president for Asia at Citrix, said it was an easy decision to choose Hong Kong as a regional headquarters. The company saw Hong Kong as a future gateway to the potentially huge China market. Citrix is a Nasdaq-listed thin-client software vendor, which allows companies to run their allocations from a server, rather than the traditional fat-client computing or mainframe model that requires computer devices with high processing power. 'We allow end-users to take applications - it can be Windows applications, Java, Unix - into one phrase rather than hundreds of personal computers,' said Mr Rose. He said the company's core application serving technology, Independent Computing Architecture (ICA), also ran on wireless devices and 'delivered server-based computing of any application on any devices on any network'. Mr Rose said ICA did not require much disc memory. 'It can basically run on Pentium III or Pentium 4 servers. It enables people to have access to their applications over very small bandwidth like 10 to 20 kilobytes per second, which is typical in the GSM connectivity space.' Mr Rose said there had been at least nine million ICA licences installed and shared by 35 million users since the system was introduced in 1995. Citrix also has offices in Singapore and India. It is due to open offices in Kuala Lumpur and Seoul in April. The company reported revenue grew from US$470.4 million in 2000 to US$591.6 million last year. Its Asia-Pacific operations, including Japan, Australia and New Zealand, saw annual revenue growth of 60 per cent. The Korean market is particularly strong. A report by International Data Corp said the Korean market for system infrastructure software was forecast to grow from US$177.4 million in 1999 to US$411.5 million in 2004. Asian clients include Pohang Iron and Steel, the world's biggest steel producer, and wireless devices developer Cyberbank, which plans to start shipping a palmtop device - PC-Ephone - this quarter which runs on Citrix's application serving software MetaFrame. Mr Rose said: 'The E-phone of Cyberbank is a very good example of Citrix's licensing applications. Users can have their phones as devices to connect to servers running on Windows, Java or Unix applications.' In Hong Kong, Citrix helped Midland Realty implement a server-based computing system after its merger with Hong Kong Property Service Holdings. The new system centralised all data among branch offices and reduced the bandwidth requirement. The leased line costs were decreased from HK$15 million in 1999 to HK$5 million this year.
