Modernising Infrastructure with Kubernetes


Improving software delivery speed, stability, and scalability through isolated environments and automated pipelines.

The client was running development, testing, and production environments on a single on-premise virtual machine using Docker Compose. This setup caused resource contention, scalability issues, and operational risk. Bion implemented isolated Kubernetes environments, improved CI/CD pipelines, and optimised database configurations. The result was a more secure, scalable, and efficient infrastructure that enabled faster releases and greater stability.

Modernising Infrastructure with Kubernetes

Client Overview

Treasy is a SaaS company providing cloud-based treasury solutions for financial institutions and banks. The platform enables full treasury front-office, mid-office, and back-office transactions, operations, and reporting. As its product matured and its customer base expanded, Treasy needed a more resilient and scalable development infrastructure to support fast iteration, strong security, and environment-specific testing.

Challenge

The client faced increasing limitations with a single shared environment, impacting development speed, scalability, and system reliability. Key challenges included:

Lack of Environment Isolation

All environments ran within a single VM using Docker Compose, causing resource contention and security concerns.

Limited Scalability and Resilience

The infrastructure was not built to scale or handle fault-tolerant workloads, limiting application growth and stability.

Inefficient CI/CD Pipelines

Manually configured pipelines lacked automation and slowed down deployment cycles and testing.

Complex Database and Resource Management

Shared configurations and infrastructure hindered performance and made it difficult to manage data and resources across environments.

Solution

Bion introduced a modular, secure, and scalable on-premises Kubernetes environment along with enhanced CI/CD capabilities.

Environment Segregation

  • Dedicated Kubernetes Clusters: Deployed isolated clusters for development, testing, and production to reduce cross-environment risks.
  • Custom Resource Quotas and Access Controls: Configured each cluster with tailored permissions and quotas, improving both performance and security.

Infrastructure Optimisation

  • On-Prem Kubernetes via Kubespray: Set up a scalable, production-ready Kubernetes infrastructure following best practices.
  • Improved Database Configurations: Optimised database setups to ensure high availability and consistent performance across all clusters.

CI/CD Pipeline Enhancement

  • Azure DevOps Pipelines: Introduced automated CI/CD pipelines using Azure DevOps Server, reducing build and deployment time.
  • Deployment Automation: Integrated tools for automated rollouts and rollbacks, enhancing delivery speed and reliability.

Knowledge Transfer and Documentation

  • Hands-on Training: Delivered in-depth training and documentation to enable the internal team to manage and extend the infrastructure independently.

Results

The new Kubernetes-based architecture and optimised CI/CD pipelines significantly improved operational performance and development agility.

Boosted Development Efficiency

Streamlined workflows and automation freed up engineering resources, allowing teams to focus on building new features.

Technology Stack

 

To support a scalable and secure development environment, the following technologies were implemented across infrastructure, deployment, and automation layers.

  • Infrastructure: On-Premise Virtual Machines, Kubernetes (via Kubespray)
  • Package Management: Helm
  • CI/CD & Version Control: Azure DevOps Server, Azure DevOps Repositories

By adopting this upgraded technology stack, the client achieved a secure, scalable, and efficient development environment, laying the foundation for long-term product growth and innovation.
