Although the procurement of cloud infrastructure from AWS was signed off by GCHQ, it will also be used by sister spy services MI5 and MI6, and the Ministry of Defence during joint operations, according to the Financial Times. The deal had not been made public and was signed earlier this year, according to the report. It is worth £500m to £1bn over the next decade, FT sources said.

AWS will host GCHQ’s and its sister agencies’ top-secret information. Spooks should find it easier to share information from field locations overseas and use AWS tools like speech recognition and machine translation for faster processing of intercepted recordings. It will also gives spies the tools to run faster searches on each others’ databases.

Selecting a US cloud provider raises some questions about the UK’s digital sovereignty. FT sources said GCHQ initially sought a UK provider but couldn’t find a domestic player with the required scale or capabilities.
