Scale Look-to-Book Ratio for Online Travel Agent System


A large international tour operator provides 24-hour services to its travel agents and Internet shoppers on HPE NonStop servers. Utilizing the Internet, the tour operator’s business grew and look-to-book ratios increased several-hundred fold.


The search query volume carried such a heavy load that the system ran out of capacity. The tour operator needed to scale-out the query system to a multi-node, distributed solution based on commodity hardware.




  • Use HPE Shadowbase Data Integration for integrating heterogeneous systems
  • Scale query load capacity in a master-subordinate relationship, replicating from the HPE NonStop booking system to both NonStop and Windows query “looking” systems
Diagram depicting Internet users use a look application which runs on a Windows Server for scalability, and is related to a NonStop server look app for processing. Then, users book on a booking app on a NonStop Master Node, then the booking app updates are sent to the look application.
