AWS, on the other hand, appears to be seriously committed to keeping its facilities safe.
"AWS data centers are housed in nondescript facilities, and critical facilities have extensive setback and military grade perimeter control berms as well as other natural boundary protection," Amazon's white paper explains.
If the purpose of building "nondescript facilities" is to escape notice, one would think that the presence of something as eye-catching as "military grade perimeter control berms" undermines any attempt at architectural stealth.
Still, it's nice to know that AWS data centers are defended against vehicles because you really don't want cars careering into server stacks.
At AWS data centers, physical access is controlled at the perimeter and building entrance by security professions using video, intrusion detection systems, and "other electronic means." You may be tempted to believe that's a reference to a Pleo in watchdog mode, but AWS almost certainly has deployed something more formidable.
