Challenge: Transform Legacy Login Service for a Sustainable Travel Partner in 3.5 months

The client sought assistance in replacing the legacy login service with one of its customers – a distinguished railway company that provides eco-friendly train travel solutions in Sweden and Norway. The service required an update without changing the main application structure and user behavior and leveraging top-notch cloud capabilities to create a secure and seamless user experience.

The main challenge was modernizing an outdated login solution without jeopardizing business processes and customer experience and with no downtime for maintenance. The client required developing the solution using their current technological infrastructure and ensuring that it could easily adapt to future updates or potential changes.

On top of that, the project scope required a team of professionals experienced in working with complex enterprise systems to deliver the solution in time and with minimum disruptions.

Solution: Optimized Architecture for Seamless User Experience

The client partnered with DataArt to deliver a solution specifically designed to flawlessly connect the main train booking application customers with their existing global online solution, automatically redirecting them to the proper entity.

To achieve this, DataArt carefully analyzed the existing legacy architecture of the client's solution and offered a specific scope of services aligned with the project's tight timeline and budget.

Additionally, DataArt used their expertise as a certified AWS Travel and Hospitality Partner and experience in working with complex enterprise architectures, to integrate the client's cloud and security model into AWS. Since the initial client’s architecture was built on AWS, the team created similar environments within DataArt's AWS ecosystem for faster solution development and testing while the client's AWS environments were being provisioned.

Outcomes

As a result, DataArt's engineers elegantly developed the architecture to provide the same integration behavior supporting co-existence with the legacy system. DataArt helped deliver a secure, future-proof, and cloud-agnostic solution to enable the client to switch between providers by adjusting the application's cloud setup.

Highlights

DataArt team planned and successfully performed gradual migration from the legacy system to minimize possible risks related to the end-user experience.
The solution supports extended non-functional requirements, including high availability and scalable architecture. Whereas a reduced set of whitelisted frameworks and libraries can be used and comply with logging standards to send application logs to Elasticsearch / Kibana.
DataArt developed the project focused on reducing the Total Cost of Ownership (TCO). The application complies with modern processes and the client's Software Development Life Cycle (SDLC), ensuring smooth and easy support and evolutionary maintenance.
The developed solution was integrated with several systems, while DataArt managed to keep the upfront budget under tight control by avoiding considerable re-engineering efforts.
Project execution took only 3.5 months, aligning with the initial timeline.
