Architecture & System Design

Overview

Architecture standards govern how systems are structured, integrated, operated, modified, and supported by approved technology.

Choose a standard below to read it in full.

A service is scoped to one business domain, so it can be built, deployed, and evolved independently.

A schema is owned by exactly one service and evolves through version-controlled, backward-compatible changes.

Every API follows a contract-first design and versioning approach so breaking changes do not affect existing consumers unexpectedly.

Every event has a defined contract and delivery guarantee; every consumer safely tolerates duplicates.

Health data is exchanged using recognised interoperability standards and shared clinical terminology.

A workload's packaging, runtime model, and deployment location are selected according to its requirements.

Every technology is classified as approved, trial, or deprecated, and a new technology is approved before adoption.
