NHS architecture principles

Public cloud first

Summary

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

Rationale

Cloud services provide many advantages for NHS Digital, including a reduction in the time to deploy infrastructure and a significant reduction in emissions.

Implication

Digital services should be delivered from the public cloud unless there is a reason not to do so. For example:

  • service level characteristics, such as availability or recovery time objective (RTO) times, that cannot be met by public cloud
  • cyber or information governance that cannot be met by public cloud

This should be reflected in architecture designs and assessed by the Architecture Approval Group.
