Modernizing Lisbon’s ticketing system with Oracle Cloud

At Linkroad, we helped Transportes Metropolitanos de Lisboa (TML) modernize and optimize its critical ticketing platform by migrating it to Oracle Cloud Infrastructure (OCI). The project delivered a scalable, secure, and high-performing system capable of supporting millions of transactions daily. With a managed services model, TML now ensures 24/7 availability, enhanced security, and cost-efficient operations, paving the way for future integration with Mobility-as-a-Service (MaaS) solutions.

Lisbon Ticketing Platform Cloud Migration on OCI

Objective: To modernize TML’s ticketing platform by migrating from legacy infrastructure to Oracle Cloud Infrastructure (OCI), ensuring high availability, resilience, and compliance while reducing operational costs.

Cloud & InfrastructureCloud Migration Managed ServicesSecurity & Compliance

Challenges

Migrating a high-volume, mission-critical ticketing system with minimal disruption.

Guaranteeing high availability during peak traffic.

Ensuring compliance with GDPR and financial regulations while protecting sensitive passenger data.

Reducing infrastructure costs without compromising performance or security.

Our approach

We migrated TML’s ticketing platform to a multi-region, high-availability Oracle Cloud Infrastructure (OCI) environment. Core backend services such as fare calculation, ticket validation, and transaction logging were containerized with Oracle Kubernetes Engine (OKE) and supported by Oracle Autonomous Database. Legacy monoliths were modularized into stateless microservices (Java/Spring Boot, Node.js, Python) for scalability. Security was reinforced with OCI Firewall, IAM, and automated monitoring. A 24/7 managed services model was implemented using Infrastructure as Code (Terraform), CI/CD pipelines, and ITIL v4 best practices, ensuring secure, automated, and cost-efficient operations.

Outcomes

Faster ticket validation and improved transaction processing.

99.9% uptime SLA with uninterrupted service during peak demand.

Reduced operational costs thanks to a flexible cloud-native model.

Improved scalability and readiness for future MaaS integration.

Better data insights to guide transport policies and innovation.

TML’s cloud migration showcases how public transportation providers can embrace digital transformation to achieve resilience, scalability, and smarter mobility services.
