Scalable and secure cloud infrastructure with AWS EKS and CI/CD automation
A fintech company in the online payment sector was faced with the challenge of making its cloud infrastructure for containerized applications more efficient, scalable and secure. The aim was to create a highly available environment with optimized CI/CD processes to enable smooth and secure deployments.
The BITS team was commissioned to design and implement the architecture.
A robust solution was developed on the basis of AWS EKS (Elastic Kubernetes Service), which is flexibly adaptable and versionable thanks to Infrastructure as Code (AWS CDK).
A monitoring and logging system with LGTM (Loki, Grafana, Tempo, Prometheus) was integrated to ensure comprehensive monitoring and error analysis. In addition, automated rollout and rollback strategies ensure high availability and operational efficiency.
The new cloud infrastructure has not only enabled the company to optimize scalability and performance, but also to efficiently implement security and compliance requirements such as PCI DSS.
Challenge
Various technical and organizational challenges had to be overcome as part of the project:
Realization
In order to meet the fintech’s requirements for scalability, security and automation, the BITS team developed a high-performance cloud infrastructure based on AWS EKS (Elastic Kubernetes Service). This managed Kubernetes environment enables a highly available and fail-safe platform for containerized applications.
Thanks to the Infrastructure as Code (IaC) strategy with AWS CDK (Cloud Development Kit), all infrastructure components could be defined declaratively, versioned and deployed automatically. This ensures faster deployment, lower error rates and transparent change tracking.
To ensure smooth software deployment, BITS implemented a modern CI/CD pipeline with GitHub Actions and ArgoCD. This automation reduces manual effort, minimizes downtime and ensures that new versions are rolled out efficiently and securely.
To ensure comprehensive monitoring and error analysis, a powerful monitoring and logging system has been integrated with LGTM (Loki, Grafana, Tempo, Prometheus). This enables a detailed analysis of system metrics, performance data and error logs in real time.
As security is a top priority in the financial sector, a security-first approach was pursued. AWS IAM, Secrets Management, network policies and a PCI DSS-compliant architecture ensure the highest security standards and protect sensitive customer data.
Automatic rollback strategies are another key feature of the solution. These detect faulty releases at an early stage and enable the previous stable version to be restored immediately, thereby reducing operational interruptions to a minimum.
With this innovative cloud infrastructure, the fintech benefits from scalable performance, automated workflows and maximum security – ideal for the dynamic online payment business.
Conclusion
With the support of BITS GmbH, the fintech was able to implement a highly available, secure and scalable cloud infrastructure that meets the high requirements of the online payment sector.
The combination of AWS EKS, CI/CD automation, infrastructure as code and comprehensive monitoring ensures an efficient and future-proof solution.
