IZBooking: Delivering a real-time travel commerce and auction platform on AWS.
Cloud modernization · AWS infrastructure · Multi-tenant architectureAT A GLANCE
The project at a glance.
IZBooking operates a travel commerce model combining tours, cruises, experiences and real-time auction mechanics. Its marketplace connects B2C travelers, B2B travel agencies and transportation operators across Vietnam and Southeast Asia.
TitanBases successfully delivered the AWS infrastructure and integration engagement for IZBooking. The technical scope is grounded in the May 30, 2026 SOW, including multi-tenant architecture, transactional data, event-driven services, operations and security. SOW metrics are shown separately as engineering criteria, not as independently verified production measurements.
Solution delivered by TitanBases
- Implemented merchant and tenant edge routing with Amazon CloudFront, AWS WAF, CloudFront Functions and KeyValueStore.
- Deployed the application platform on Amazon ECS (EC2), an Application Load Balancer and two Availability Zones with six microservice groups.
- Integrated transactional data, events and notifications with Aurora PostgreSQL, MemoryDB, DynamoDB, SQS, EventBridge, Lambda and SES/SNS.
Delivery outcome and architecture scope
- AWS infrastructure and integration project successfully delivered.
- Multi-tenant architecture designed to support up to 1,000 merchant subdomains.
- Traffic, latency, availability and notification thresholds are SOW requirements, not substituted for measured production outcomes.
ABOUT IZBOOKING
More than a booking platform. A connected travel marketplace.
IZBooking develops a digital travel marketplace that brings together discovery and booking of tours, cruises and experiences with dynamic auctions. Unlike a traditional OTA, the platform combines limited-slot travel inventory, demand-driven bidding windows and booking journeys in one digital experience.
Its three-sided model connects individual travelers, travel agencies and transportation operators. Beyond bookings and auctions, IZBooking incorporates geolocation- and anomaly-based review fraud checks, along with loyalty points and rewards.
Discovery and bookings
Tours, cruises and experiences in one travel marketplace.
Real-time auctions
Dynamic bidding windows, limited-slot inventory and demand-driven pricing.
Reviews and fraud protection
Geolocation review validation and anomaly detection.
Loyalty and rewards
Points and rewards integrated with the booking workflow.
TitanBases successfully delivered AWS infrastructure and the integration layer for a multi-tenant architecture supporting booking, auctions, reviews and loyalty workloads. Application business logic and the frontend remain in IZBooking’s development scope under the SOW.
THE CHALLENGE
Business challenge · Concurrency · Resilience · Tenant isolation
When every auction second can determine a booking.
IZBooking unites traditional OTA commerce and dynamic auctions: limited seats, demand-driven pricing and concentrated bidding near auction closing windows. B2C travelers, B2B agencies and transportation operators need tenant-aware access to one shared platform.
Engineering requirements spanned tenant-aware routing, durable bid state, consistent booking and loyalty transactions, event-driven alerts and review fraud detection.
TitanBases delivered AWS infrastructure and the integration layer per the SOW. Booking engine business logic, auction algorithms and frontend UI remained in the customer’s application-development scope.
ENGINEERING AT SCALE · DELIVERED PROJECT
One AWS architecture. Many merchants. Consistent transactions.
TitanBases delivered the infrastructure and integration platform based on the SOW architecture: tenant-aware edge routing, ECS application services and dedicated data and event services supporting booking, auctions and loyalty.
Project delivery is complete. These are design-scope figures, not observed merchant count or production traffic.
THE SOLUTION
AWS architecture · Edge · Containers · Data · Events
An AWS architecture delivered across workload-specific layers.
AWS WAF and Amazon CloudFront protect the edge, while CloudFront Functions and KeyValueStore support merchant-subdomain routing. An Application Load Balancer distributes traffic to Amazon ECS (EC2) services in private subnets across two Availability Zones. Six scoped microservices cover bookings, auctions, review and anti-fraud, OTA pricing, loyalty and tenant configuration.
Amazon Aurora PostgreSQL handles transactions; MemoryDB for Redis handles bid and session state; DynamoDB covers auction and merchant configuration data; and OpenSearch supports search and review filtering. SQS, EventBridge, Lambda and SES/SNS support asynchronous services, while S3, ECR, Secrets Manager, IAM/KMS, CloudWatch, CloudTrail and Config support delivery, security and operations.
