The internet is what made IoT happen, providing a common protocol to take the place of separate, specialized networks. But the public internet itself may not always be the best path between a connected device and the cloud.
Enterprises can now connect cellular IoT devices to back-end systems via NetBond, a private network service from AT&T, instead of the Internet. The NetBond service sets up a VPN (virtual private network) from an edge device to the cloud. It can connect to 16 different public clouds, including Amazon Web Services and Microsoft Azure, or a private or hybrid cloud.
