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.  SEE: These stealthy hackers avoid Windows but target Linux as they look to steal phone data In a February opinion piece for the Financial Times, GCHQ director Jeremy Fleming said that the agencies “expect AI to be at the heart of this transformation and we want to be transparent about its use.” So-called “good AI” would allow “analysts to deal with ever increasing volumes and complexity of data, improving the quality and speed of decision-making.” This could include identifying and countering troll farms peddling fake news, as well as tracking networks that traffic people, drugs or weapons, Fleming noted. 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.
