Provisioning mechanisms of IoT devices

[zyetta]

I'd like to discuss the provisioning mechanisms of IoT devices and why it's important.

Background
IoT devices require an initial setup and configuration to have appropriate network access.
For smaller projects, this may be manually performed. But how is this done on a larger scale.

Methods to discuss:

1. Manual and its purpose
2. Bulk/templating
3. Zero-touch provisioning
