Migrating a Swiss Digital Bank from OpenShift to AWS EKS
About the End Customer
Our end customer is a Swiss digital bank for anti-money laundering built for crypto transactions. They are in the market to transform the way people do banking and incorporate digital assets into regulated institutions. They aim to give people control and freedom when managing their own finances while using protocols that enable the secure functioning of a decentralized digital database.
What They Needed Help With
As a fintech solution, their main concern was regulations, governance, and frequent audits. They needed a team of experts to migrate their solution from Openshift to Kubernetes. So they were on the hunt for a DevOps team to support their migration while improving their existing pipelines.
The digital asset bank wanted to build an easily scalable, more responsive platform to quickly transfer data to the customer and provide an exceptional experience to end users.
A Secure Cloud Infrastructure: Implementing Terraform, Kubernetes, and Calico
As we continued to work together, we became an integral part of their product and SRE teams. We automated the provisioning of AWS infrastructure resources using Terraform, and utilized Kubernetes for workload orchestration. We also used Calico to enhance security, and provide isolation. Overall, our efforts played a key role in helping our end customer achieve their desired outcomes.
Terraform: Maximizing Efficiency and Streamlining Infrastructure Management
We implemented Infrastructure as Code (IaC) and DevOps practices to automate the provisioning and management of the infrastructure and deployments, improving productivity, increasing quality, and decreasing delivery time. The entire execution of the project followed an IaC approach using Terraform, and Atlantis for automating Terraform via pull requests.
We provisioned and maintained AWS resources and improved existing Gitlab pipeline templates based on their needs. Running on AWS EKS as a multitenant solution, we've set up dynamic resource provisioning based on available tenants (B2B clients). Creating a multitenant architecture makes the product available for many customers, white-labeling it, and selling it as a company-branded service.
Kubernetes: Facilitating Agility, Modernization, and Efficiency
Container orchestration technologies provide the foundation for managing microservices and architecture at scale. Kubernetes is the best open-source container orchestration platform for Fintech companies to facilitate developer agility, modernization, and operational efficiency.
Containers allow Fintechs such as our end customer to develop an executable bundle of software that is abstracted away from (not connected to or dependent on) the host operating system so that it can execute uniformly and reliably across any platform or cloud.
Calico: Our Approach to Kubernetes Networking and Security
To build workload isolation in multi-tenant environment we turned to Tigera’s Calico for microsegmentation. Calico is an open-source networking and security solution for containers, virtual machines, and baremetal host-based workloads.
Its comprehensive networking and security policy architecture made it simple to restrict communication and control the traffic flow between workloads inside the cluster and to the external parties outside the cluster. Its security policy engine applied the same policy model at the host networking and service mesh layers, safeguarding client’s infrastructure from compromised workloads and client’s workloads from compromised infrastructure.
This allowed client to build and manage container clusters with Kubernetes while securing their containerized workloads with Calico.
How DevOps Helps Fintech Organizations Like Our Client

Our team's expertise in Kubernetes enablement made us the perfect choice to help our end customer build a secure, scalable, and reliable platform.
As a Kubernetes Certified Service Provider and Tigera partner, we have the knowledge and advanced expertise in consulting and providing professional services for organizations embarking on their Kubernetes journey.
Although it is increasingly easy to spin-up a Kubernetes cluster, it can be challenging to implement Kubernetes in a way that aligns with your company's needs. Many applications may not be ready for containerization, making it difficult to take the first steps towards a cloud native environment. We help guide you through the process, providing the necessary services, software, and support to run a production-grade Kubernetes infrastructure in a secure, reliable, scalable, and efficient manner.
