// 03 Challenge
Bringing a secure private cloud — software-defined networking (BGP, IPsec tunnels, routing, subnets, firewalling and security), infrastructure-as-code and a developer workflow engine — up to the reliability and security standards expected of a critical energy-sector operator, primarily through advisory and quality-assurance work.
noriba supported a secure private-cloud programme for a critical energy-sector infrastructure operator. The engagement was weighted toward quality engineering and technical consultancy, with a smaller share of hands-on development — roughly 40% quality assurance and testing, 40% consultancy and 20% development.
As technical consultants, we helped shape the software-defined networking (BGP, IPsec tunnels, TCP/IP, IPAM, routing, subnets, firewalling and security), the infrastructure-as-code approach (Terraform, Ansible, Kubernetes) and the design of a developer workflow engine and VPN-secured workspaces. The largest part of the work was quality assurance and testing: verifying platform services, automation and network behaviour against the security and reliability standards expected of critical infrastructure, with automated test suites (pytest) run through GitLab CI/CD and Flux CD. Our development contribution was delivered in Python (FastAPI, Pydantic).
