Multi-Product Travel Search
Users can search flights, hotels, rail, buses, insurance, and travel packages through a unified experience connected with multiple external inventory and pricing providers at scale.
Cloud-Native B2B Travel Portal Development Platform
A scalable travel technology platform that unifies flight, hotel, rail, bus, insurance, and package booking through real-time supplier integrations, event-driven services, and a cloud-native microservices architecture designed for reliable global operations.
Project Overview
We developed a cloud-native travel booking and aggregation platform that brings multiple travel products and supplier connections into one scalable ecosystem. The solution supports real-time search, pricing, booking, ordering, payments, and shared operational data across flights, hotels, rail, buses, insurance, and travel packages. Built with .NET Core, CQRS, Dapr, Redis, PostgreSQL, Docker, and Kubernetes, its independently deployable services improve scalability, system resilience, and maintainability. Centralized identity, API routing, observability, and supplier integrations provide a reliable foundation for travel operators serving multiple products, users, and markets.
Tackling the Complexities of Travel Tech Modernization
From monolithic legacy tools to container scaling issues, the platform required a total transformation to deliver modern, scalable b2b travel software development capabilities.
Fragmented Travel Booking Operations
Travel products, supplier connections, and operational workflows were distributed across disconnected systems, making it difficult to provide customers with one consistent search and booking experience.
Difficulty Scaling Multiple Travel Products
Adding suppliers, markets, and travel products increased architectural complexity because integrations, business rules, and booking workflows could not evolve independently within the existing environment securely.
Complex Third-Party Supplier Integrations
Each travel provider exposed different availability models, pricing structures, APIs, and booking rules, creating a need for standardized integration and reliable data orchestration more reliably.
Distributed State and Transaction Integrity
Coordinating inventory, orders, and payments across independent services introduced risks around shared state, caching, event sequencing, failures, and transactional consistency during multi-step bookings at scale.
Deployment and Infrastructure Complexity
Multiple services required consistent containerization, configuration, orchestration, scaling, and load balancing across development, testing, and production environments without compromising platform stability through coordinated platform operations.
Limited Engineering Visibility
A distributed architecture required centralized logging, monitoring, metrics, and tracing so engineering teams could identify performance issues and follow transactions across several interconnected services reliably.
Scalable Architecture to Power Global Travel Operations
Ditstek introduced a cloud-native architecture that standardized supplier integration, separated core travel capabilities, strengthened service communication, and created a scalable operational foundation for multiple products and markets for growing businesses.
Cloud-Native Microservices Architecture
Travel capabilities were separated into independently deployable services, enabling booking modules, supplier integrations, payments, and shared business functions to evolve without destabilizing the complete platform.
CQRS-Based Service Design
Command and query responsibilities were separated to improve maintainability, clarify transactional workflows, and allow individual services to process reads and writes according to their operational needs.
Dapr-Based Service Communication
Dapr standardized service invocation, state management, configuration, and publish-subscribe communication, reducing direct dependencies while supporting reliable coordination between distributed booking and operational services more reliably.
Redis Messaging and Caching
Redis was configured for high-speed caching and event communication, improving access to frequently requested information while supporting responsive, asynchronous interactions between independent platform services worldwide.
Standardized Supplier Integration
TravelPort, Air Arabia, and TBO Hotel integrations were connected through structured services that normalize external availability, pricing, and booking information for consistent platform use securely.
Centralized Identity and Authorization
Keycloak provides single sign-on, OTP authentication, identity brokering, user federation, and controlled permissions through one secure access layer shared across the distributed platform more reliably.
Containerized Deployment Architecture
Multi-stage Docker builds reduced unnecessary dependencies, while Kubernetes automated service deployment, scaling, load balancing, and availability across development, testing, and production environments across global markets.
End-to-End Observability
Prometheus, Grafana, Loki, Promtail, Zipkin, and Serilog provide centralized metrics, dashboards, logs, and distributed tracing for faster diagnosis across interconnected services through coordinated platform operations.
Reusable Master Services
Shared services centralize countries, cities, currencies, agents, suppliers, products, and platform rules, reducing duplication and maintaining consistent information across different travel modules for growing businesses.
Feature-Rich Platform for Travel Search, Booking & Management
The platform combines real-time travel search, supplier connectivity, distributed booking orchestration, secure identity, payments, routing, shared master data, and operational observability within one extensible digital ecosystem through coordinated platform operations.
Flight and Hotel Booking
Integrated supplier APIs support current availability, pricing, selection, ordering, payment, and booking confirmation workflows across airline and accommodation products within one platform through coordinated operations.
Event-Driven Booking Choreography
Dedicated airline, ordering, and payment services coordinate booking events through publish-subscribe communication, maintaining clear responsibilities throughout complex reservation and transaction workflows within complex travel environments.
Unified Supplier Integration Layer
A standardized connectivity layer manages communication between internal services and external travel providers, limiting supplier-specific dependencies across the wider booking and operational architecture at scale.
Secure Identity and Access Management
Keycloak centralizes token-based access, OTP authentication, user federation, single sign-on, and role permissions for administrative, operational, supplier, and booking-related platform users through coordinated platform operations.
API Gateway and Service Discovery
Ocelot routes application requests through a controlled gateway, while Consul enables service discovery and configuration management across independently deployed backend components within complex travel environments.
Real-Time Caching and State Management
Redis supports frequently requested search information, distributed state, and asynchronous events, while PostgreSQL maintains reliable transactional data for ordering and booking workflows across global markets.
Centralized Observability Suite
Integrated metrics, dashboards, logging, and distributed tracing provide engineering teams with clear visibility into service performance, request journeys, communication failures, and infrastructure health with confidence.
Extensible Travel Product Architecture
The modular foundation supports additional suppliers and products, including rail, buses, insurance, hotels, and vacation packages, without requiring the overall platform to be redesigned reliably.
