Moving on – from on-premise into the cloud

Luminor was established in August 2017 on the basis of the Baltic operations of Nordea and DNB. The Client’s primary focus was to build a payment infrastructure and information systems independent of its parent banks. This was a unique project, entailing bringing together customers of the former branches of DNB and Nordea across three countries – Estonia, Latvia and Lithuania. 

The transformation was essential not only to make sure Luminor is independent of the parent institutions’ infrastructure but also to ensure more flexibility and coherence across the three Baltic countries to ensure the best customer experience going forward. 

Luminor decided to treat the carve-out process as an opportunity to move away from on-premise solutions and into AWS Cloud, to benefit from decreased maintenance costs, more flexibility and security.

What we needed was an efficient, flexible and reliable cloud infrastructure to support us in our transformation journey. Tameshi delivered just that. The expertise and experience of their team made the migration process smooth and seamless –  Gatis Setlers, Head of IT Development, Luminor.

Tameshi offered solution

Client services were grouped by functionality into ones based mostly on static data and dynamic ones. 

Services serving dynamic data were moved to EKS (Elastic Kubernetes Service), a containerized environment that allows us to isolate services from each other, increasing security and, at the same time, allowing to create strict boundaries between developers and operations through the use of artifacts. That way, all project goals were met: the cost of keeping infrastructure was lowered to a minimum, while security levels increased – says Maciej Cetler, CTO, Tameshi.

Maintaining a big infrastructure is always challenging. In this case, we used an out-of-the-box approach to minimize maintenance costs, mainly by delivering new versions of the application. Instead of keeping everything static where utilization is low, we decided to go dynamic whenever possible. Tameshi team created pipelines that dynamically added necessary pieces of infrastructure to utilize them fully. This was possible with the use of EKS in conjunction with Application and Network Load balancers, supported by Route 53. Agents responsible for different functionalities are only created on demand as EKS pods, access to them is distributed with the use of Elastic Load Balancers. This means all infrastructure is utilized when needed and terminated later, not to generate any costs.
