Wired, 'Google Throws Open Doors To Its Top Secret Data Center', October 2012
Google's Platform
"[Google's] ability to build, organize, and
operate a huge network of servers and
fiber-optic cables with an efficiency and
speed that rocks physics on its heels.
This is what makes Google Google: its
physical network, its thousands of fiber
miles, and those many thousands of servers
that, in aggregate, add up to the mother of
all clouds."

MemchacheService cache = MemcacheServiceFactory.getMemcacheService();
…
User user = cache.get(“accessToken”) ;
if (user != null) {

cache.put(“accessToken”, user, Expiration.byDeltaSeconds(DURATION_IN_SECONDS));
return user;
}
