Fostering Business Agility with Rapid Cloud Transformation for a High-speed Train Service Operator in UK & Europe

Business Challenge

Our client, high-speed train service provider linking the UK to the European continent, wanted to accelerate their digitization journey, improve their online presence and deliver a superior passenger and employee experience. They were limited by the legacy infrastructure environment, manual build & release process leading to high IT operational cost and non-alignment of SLAs with business needs. They required agility and scalability in their operations to respond to unpredictable changes like the COVID-19 pandemic. They envisioned transforming their operations through improvements in fleet, services, and stations, and sought to migrate their backend and critical applications to AWS cloud to reduce the development & release cycle and drive agility in operations.

Coforge Solution

In order to achieve the business goal, Coforge took an aggressive timeline to migrate over 50 business critical applications to AWS cloud in 5 months. An agile team was formed which adopted iterative and collaborative practices to deliver the project within the required timeframe.

Key solution aspects:

Robust, Flexible, and Achievable Plan: Delivery of services as per business criticality was planned in such a way that learning from each sprint was fed to the subsequent sprint.

Migration and Delivery Approach: Lift & shift approach using AWS migration services using agile practices by identifying key applications and their dependencies.

CI-CD: Infrastructure as a Code: Services for new project were launched using CloudFormation scripts, Jenkins and Ansible .

Monitor and Secure: Cloud tools (CloudWatch, CloudTrail, WAF) were planned and implemented.

Results

• Improved agility due to migration of 50+ business critical applications and 200+ servers from on premise IT infrastructure to cloud.
• Out of these services the major one was Departure Control System which benefited client to make passengers travel hassle free.
• Reduction of operational cost by approximately 30%.
• Infrastructure as Code helped in automating the provisioning of the environments fast without any errors
• Monitoring solution helped in debugging problems and optimizing the costs.

Key Highlight

Agile, scalable and secure platform using AWS implementation, the development environment set-up/provision time was drastically reduced, faster release cycles were achieved, and the new infrastructure supported the client's ambitious growth plans, driving excellent experiences for millions of travelers.
