The question

To ask the Secretary of State for Science, Innovation and Technology, what proportion of Government cloud services are hosted on (a) AWS, (b) Google and (c) Microsoft infrastructure.

Answered by Ian Murray

The State of Digital Government report estimates up to 60% of the government estate is currently hosted on cloud platforms, mostly using AWS, Microsoft and Google. More granular data on the split between AWS, Google and Microsoft infrastructure is not currently held. However, the Government Digital Service in DSIT is developing a cloud consumption dashboard to provide government with greater visibility of cloud usage and costs across the public sector.
