About Tink, A Visa Solution
Tink, A Visa Solution, is a payment services and data enrichment platform that offers API-based solutions for payments, banking, and lending. Tink’s platform enables banks, fintechs, and merchants to build data-driven financial services, supporting a broad spectrum of businesses across Europe.
Why Tink Needed a Feature Management Solution:
Tink operates a complex monolithic architecture that demanded safe, efficient feature releases. Additionally, given their hybrid application setup with multiple services and environments to manage, they needed a system that would allow for granular control over deployments to minimize disruptions and rollbacks.
Managing deployments in a monolithic system is particularly risky. Any issues with a feature could require rolling back an entire deployment, which is time-consuming and can disrupt all teams. Tink faced challenges in handling this complexity of rollouts and rollbacks within the monolith and ensuring that changes were safe and reversible without impacting the entire system.
The Benefits of Unleash Feature Management for Monoliths
Unleash allowed Tink to decouple feature rollouts and rollbacks from deployments. By implementing feature flags, Tink could release new features incrementally, reducing the need for large-scale rollbacks if something went wrong in one part of the monolithic application. The alternative was rolling back all changes, something that was unacceptable from a business and user experience perspective.
The Business Outcomes of Unleash:
By using Unleash, Tink significantly improved deployment safety. They could turn off specific features if issues arose, without risking full rollbacks. This led to smoother releases, faster deployment cycles, and more confident developers. Even with the complexities of managing a monolithic architecture, Unleash helped Tink scale feature toggling across their many services and environments.
Conclusion:
For Tink, Unleash was a game-changer in managing feature rollouts within a monolithic architecture. The platform gave their teams the flexibility and confidence to deploy changes incrementally, reducing the risks and delays associated with large-scale rollbacks. Unleash continues to be a vital tool as Tink scales its services and expands its feature set.
