Provisioning devices that have device certificates

Amazon IoT provides three ways to provision devices when they already have a device certificate (and associated private key) on them:

  • Single-thing provisioning with a provisioning template. This is a good option if you only need to provision devices one at a time.

  • Just-in-time provisioning (JITP) with a template that provisions a device when it first connects to Amazon IoT. This is a good option if you need to register large numbers of devices, but you don't have information about them that you can assemble into a bulk provisioning list.

  • Bulk registration. This option allows you to specify a list of single-thing provisioning template values that are stored in a file in an S3 bucket. This approach works well if you have a large number of known devices whose desired characteristics you can assemble into a list.
