National Health Information System — Infrastructure Readiness & Performance Planning

A national health program needed its health information platform — built on DHIS2 — to operate reliably at national scale, with clear security, availability and performance expectations across the whole environment.

Ubuntu, Nginx, Tomcat, PostgreSQL, DHIS2, storage and network services.

Production readiness questions across the stack: sizing, reliability, security posture and the operational risks of running health data at national scale.

Reviewed the target architecture and its operational layers from Linux and PostgreSQL up through Tomcat, Nginx, security controls and monitoring.

Defined implementation plans and infrastructure requirements across the stack, and specified secure, resilient architecture expectations for the platform rollout.

A clear readiness and implementation plan covering architecture, security, monitoring and operations for the national rollout.

In national-scale health systems, the application is only part of the risk — availability, security and operations decide whether the program succeeds.
