Case Study: Large Japanese Travel Agency achieves data‑center independence and scalable, cost‑efficient operations with IBS Software (AWS migration)

Achieving Data Center Independence with Public Cloud Services

Large Travel Agency, a Japan‑based travel firm with 500+ branches and 18,000 employees, faced surging demand, exponential look volumes after metasearch integration, and an expiring data center contract. IBS Software recommended and led a migration to Amazon Web Services (AWS), using services such as AWS RDS, AWS ALB, EC2 and Route 53 to address scalability, cost and business‑disruption concerns.

IBS Software re‑engineered parts of the application and executed a staged, zero‑downtime migration—moving scheduled jobs, the transaction database, and end‑user applications, deploying EC2/RDS across multiple AZs, shifting SSL termination and URL routing to AWS ALB, removing IP hardcoding, and enabling monitoring with CloudWatch/ELK and traffic splitting via Route 53. The project delivered measurable results: about 35% annual infrastructure cost reduction, decommissioning 65+ servers with full data center giveback, and an additional ~20% savings from further optimizations, while improving availability and scalability.
