Business Overview
As one of France’s leading digital banks, this organization serves more than four million customers through a fully online platform offering savings, investment products, loans, insurance, and rich financial education tools. Their competitive advantage stems from low fees, intuitive digital services, and a strong culture of technological innovation. To maintain this leadership—and to keep pace with customer expectations—the bank continually invests in its digital infrastructure. With over 1,500+ environments running critical financial services, their engineering and platform teams knew they needed a smarter, more efficient way to deploy applications, maintain security, and scale innovation
Challenges
The bank recognized that its manual container processes were holding back innovation and risking security:
- Complex scripts and configurations were required to deploy applications manually
- Inconsistencies between development, test, and production environments increased risk
- Onboarding new software could take up to five days
- Debugging and log management were cumbersome and resource-intensive
- Ensuring security and compliance across hundreds of environments posed growing concerns
Solution
The bank evaluated container tools and selected Portainer Business Edition for its balance of security, simplicity, and manageability:
- Portainer’s intuitive UI enabled standardized Docker and Kubernetes deployments
- Role-based access controls (RBAC) secured access across over 1,500 environments
- Edge Agents and Edge Stacks made it easy to launch apps from a single central node
- GitOps integration streamlined CI/CD, syncing deployments from Git automatically
- The unlimited licensing model offered predictable cost even at large scale
