Minerva Technologies

Minerva branded

Minerva Technologies, a nascent startup situated in Milan, meticulously marries the realms of computer science, mathematics, physics, finance, and economic theory, employing a scientific method approach to transform the art of decision-making. By harnessing sophisticated algorithms and quantitative analyses, and underpinned by our proficiency in big data management, they empower Executives to make well-informed strategic and tactical choices. Their methodology, deeply embedded in the scientific method, emphasizes empirical evidence and rigorous research, facilitating a perpetual refinement of our practices in these core disciplines. The outcome is a collection of research-based reports and insights, meticulously designed to navigate the complexities and fluidity of the contemporary corporate landscape. This synthesis of interdisciplinary expertise and scientific methodology underscores their dedication to pioneering solutions that resonate with the nuanced demands of today’s businesses.

Looking at this retrospectively, the migration process would have been a lot more manual without SysDojo.

Their expertise ensured seamless integration of Proxmox, pfSense, and Kubernetes within Hetzner’s infrastructure, meeting critical deadlines without compromising quality. Their partnership has been invaluable in achieving our goals efficiently.

  1. Security Concerns: The client stressed the importance of stringent security measures to protect sensitive user data and prevent unauthorized access, particularly under the pressure of a tight deployment schedule.
  2. Scalability Requirements: As their user base continued to grow rapidly, the client required a scalable infrastructure solution capable of accommodating increased traffic and workload demands.
  3. Complex Networking: Integrating Proxmox servers with pfSense firewalls and ensuring seamless OpenVPN access added complexity to the deployment process.
  4. Kubernetes Deployment: Implementing a Kubernetes cluster with master, worker, and Nginx nodes demanded careful planning and execution to ensure optimal performance and reliability.


  1. Proxmox Installation on Hetzner Infrastructure: Leveraging the robust capabilities of Hetzner’s infrastructure, we deployed Proxmox servers to provide virtualization and containerization capabilities. This allowed for efficient resource utilization and simplified management of virtualized environments.
  2. Integration of pfSense Firewalls: To enhance security and facilitate remote access, we installed pfSense firewalls on top of the Proxmox servers. Configuration of OpenVPN ensured secure and seamless connectivity for authorized users, while stringent firewall rules mitigated potential threats.
  3. Kubernetes Cluster Deployment: With the foundation in place, we proceeded to deploy a Kubernetes cluster to orchestrate containerized applications effectively. This involved setting up master nodes for control plane management, worker nodes to execute application workloads, and ingress nodes to manage inbound traffic through ingress routing.
  4. Configuration of Ingress Controller (Nginx): Nginx was configured as the ingress controller to route external traffic to the appropriate services within the Kubernetes cluster. This facilitated efficient load balancing, SSL termination, and path-based routing, optimizing application performance and accessibility.


  1. Enhanced Security: The integration of pfSense firewalls with Proxmox servers provided robust perimeter security, protecting the client’s infrastructure from external threats and unauthorized access.
  2. Scalability and Flexibility: The Kubernetes cluster architecture allowed for seamless scalability, enabling the client to accommodate increased workload demands and adapt to evolving business requirements.
  3. Improved Performance: Nginx ingress routing optimized traffic distribution and load balancing, resulting in improved application performance and responsiveness.
  4. Streamlined Management: Centralized management through Proxmox simplified administrative tasks, while Kubernetes provided automated deployment and scaling of containerized applications, reducing operational overhead.
  5. Cost-Efficiency: By leveraging Hetzner’s infrastructure and open-source technologies, the client achieved cost efficiencies without compromising on performance or security.


Our swift and successful integration of Proxmox servers, pfSense firewalls, and Kubernetes cluster deployment within the Hetzner infrastructure not only underscores our unwavering commitment to delivering innovative and tailored solutions but also highlights our agility in meeting tight deadlines. By effectively addressing their security, scalability, and performance imperatives, we have empowered our client to excel in a fiercely competitive digital environment, positioning them for enduring growth and prosperity.
