Case Study: World’s Leading Cruise Lines achieves 90% reduction in business-critical response time with IBS Software

Technology upgrade for a cruise line to achieve 90% reduction in business critical response time

World’s Leading Cruise Lines, one of the world’s largest private cruise operators with presence in 70 countries and nearly two million guests a year, struggled with a legacy mass file transfer cache that delivered stale XML data to partners and vendors. Dynamic data like fares and inventory changed rapidly, causing overbookings, mismatched invoices, inefficient partner operations and poor guest experience. IBS Software was engaged to modernize the data cache and search stack (implementing Couchbase for the cache and Elasticsearch for search) to enable near real‑time, permissioned data access.

IBS Software built a high‑performance Couchbase-based data cache and deployed Elasticsearch across B2C and B2B touchpoints, enabling near real‑time retrieval and powerful distributed search. The engagement delivered a ~90% reduction in inter-system response time (from ~2 seconds to ~200 ms), a 20% overall system performance improvement, search scale from under 1M to 4M+ records with monthly growth of 1M+, and search combinations rising from <5 to >27 — eliminating overbooking, synchronizing partner bookings, and materially improving guest experience and vendor integration.
