Amazon Greengrass and FreeRTOS

I’m wanting to make sure the capabilities of Amazon Greengrass is easier for integration.

Does Amazon Greengrass provide automatic provisioning of new devices where very little coding is involved setting up devices with the new certificates “things”?

How is the unique certificate “thing” setup in Amazon server side with the greengrass implementation?

We started down the route of using the stock Amazon RTOS instance that doesn’t really provide the OTA updates, so we’re looking at alternatives that includes the OTA updates provided by greengrass. We started sending the certificate pem and keys inbound on a MQTT subscribe and overwriting the original certs with the unique certs (for better security). But thinking that Amazon Greengrass will provide all of these out of box.

Maybe I’m missing something completely.

I’m planning on trying out the FreeRTOS OTA demo application to see if I can see if things are easier than the way were doing things now. We’re currently using the Ti CC3200SF-LAUNCHXL development board.

Any help will be greatly appreciated.
