How We Built a High-Load Tourism System with Instant Request Processing
The tourism market is rapidly evolving. Travel agencies and online platforms handle huge volumes of data daily: finding suitable properties, checking availability, and updating prices. This is especially crucial when booking houses and villas — a segment where customers expect accurate and instant information.
Initial Situation
A company providing property booking services for tourists approached us. Their system aggregated offers from dozens of suppliers and delivered them to agencies. However:
- the process took too much time;
- the property database was limited;
- the system froze under heavy loads;
- the API couldn’t handle requests and responded with delays of tens of seconds.
Management realized: in tourism, a slow search means losing customers. They needed a scalable architecture capable of handling hundreds of thousands of requests per second.
Solution: Reworking the Architecture and API
We conducted a detailed audit and offered a comprehensive upgrade:
- New architecture. Migrated to a microservice approach with dedicated modules for data collection, normalization, search management, and results delivery.
- API optimization. Rebuilt API with asynchronous processing, caching of popular queries, and optimized response structures.
- Faster search. Distributed databases and indexing reduced response time from tens of seconds to less than 200 ms.
- Scalability. Horizontal scaling allows growth in suppliers and requests without performance drops.
- Monitoring & analytics. Built-in tools to track load, detect bottlenecks, and prevent failures.
Results After Implementation
- the number of properties (houses, villas, apartments) increased several times;
- API response time dropped to fractions of a second, even under peak loads;
- the system now handles hundreds of thousands of requests per second;
- partner agencies gained a fast and convenient tool for property search;
- the client’s business scaled and entered new markets.
Additional Opportunities
We ensured flexibility for growth: adding new suppliers, expanding property types, integrating with external CRMs and booking systems. The architecture allows new modules to be added without downtime.
Conclusion
The system, once limited in speed and data volume, was transformed into a powerful solution for the tourism industry. The reworked architecture and optimized API provided instant request processing and allowed the client to become a competitive player in the international market.
Tourism is about speed, accuracy, and scale. With this solution, agencies get access to an up-to-date property database, and users enjoy instant search results.
