Hi Nikita
Akamai runs what's probably the world's largest set of caching servers, they run a content distributions system used by major websites to provide fast web response on a global scale.
AWS is a cloud computing service used by a large number of companies for caching internet content
I know Norton Anti-Virus use this among a lot of other software companies, and as far as I know, so does Microsoft, this is a legitimate caching service and is honestly nothing to worry about . . .
