By alexismp on Aug 21, 2008
Australia's Wotif.com is a successful business that has grown quite a bit in the past year and a half, becoming the number one hotel website in both Australia and New Zealand. Each month, Wotif.com attracts over 3.2 million visitors and processes more than 200,000 bookings for 11,000 hotel partners around the world as explained in this detailed story.
Beyond Wotif.com's extensive use of GlassFish, this story also mentions who they migrated from Apache Active MQ 3 to Open Message Queue 4.0. Architect Greg Luck calls "Open Message Queue to be faster than Active MQ and rock solid in production”. You'll find more details on this slide deck and this set of videos.
