NHS architecture principles

Deliver sustainable services

All services need to be delivered sustainably.

Put our tools in modern browsers

All digital services should be browser based and utilise open web standards.

Internet first

All digital services should adopt internet standards and protocols, including that services are available over the public internet by default.

Public cloud first

Digital services should move to the public cloud unless there is a clear reason not to do so.

Build a data layer with registers and APIs

Digital services should only store data once and make it available via open APIs whilst maintaining privacy and security.

Adopt appropriate cyber security standards

Services must adopt the appropriate cyber security standards, subject to risk appetite, including keeping all software, networks and systems up to date​​.

Use platforms

Digital services should build upon existing platforms to deliver their services.

Put user needs first

Every service must be designed around user needs, whether the needs of the public, clinicians or other staff.

Interoperability with open data and technology

Digital services should adopt open data and technology standards.

Reuse before buy/build

Digital services should demonstrate that they have sought to reuse existing solutions before delivering new ones.
