Little devices that use huge cloud servers to do your bidding
The big brains of tech.
Right now, in a data center far, far away, gargantuan cloud servers are providing brainpower to devices as minute as fitness trackers. At first glance, for example, a baseball-size connected camera is nothing more than simple home surveillance; what you don’t see, however, is that it can employ thousands of servers to enable image recognition, allowing it to know the difference between a human and, say, a moving tree branch. Machine armies undergird countless teeny-tiny devices. Here are five of the smartest:
Last year, homeowners connected some 4 billion devices to their networks. Dojo by BullGuard keeps hackers from exploiting them. The 6-inch box plugs into your router, monitors traffic, and cuts off any shady activity. Meanwhile, Dojo’s server looks for patterns across all its relatives to thwart bigger threats. $199.
Nest Cam Outdoor Security Camera
The Nest Cam Outdoor is always watching, but it needs help to know what it’s looking at. With the Nest Aware service, footage uploads to the company’s servers, where computer- vision algorithms distinguish a person from Spot chasing a squirrel. Those smarts reduces false-positive intruder alerts. $179 plus $10 per month.

Armed with data from more than 200 million users, Under Armour motivates athletes with what drives them most: competition. The UA Record app and HealthBox kit—which includes a heart-rate monitor, fitness tracker, and scale—tap into an IBM-powered virtual coach that stacks up users against other athletes. $220.
Amazon Echo Dot

The Alexa-powered voice-activated assistant passes commands through Amazon’s cloud- based natural language processing to understand and carry out over 9,000 skills, including setting alarms, hailing an Uber, and reordering Doritos. $50.
Imaginary friends, meet the competition. Backed by Watson’s encyclopedic memory bank, a custom speech algorithm, and a weekly-updated roster of games, facts, and stories, CogniToys Dino is a clever, greg- arious (and adorable) 6-inch chatterbox. It also builds a profile of its human buddy, like if a kid is into pizza or soccer. $100.
