Wi-Fi networks are essential, but difficult and expensive to deploy and manage. Therefore, many companies are handing off the tasks to others. Note-taking app developer Evernote outsourced its wireless network to startup Meter, and home improvement retailer Home Depot to Aruba, a Hewlett Packard Enterprise company. Both tech buyers determined that the loss of network control was worth eliminating IT work that wasn’t core to their businesses. “I can essentially get the same services from a vendor for less without the headache, and I can reallocate my people to work on other projects,” said Gabe Raffaelli, IT director at Evernote.
