IoT Greengrass multiple core devices

Hello,

Each Greengrass device should be an individual device, you cannot share a Greengrass installation across multiple devices. To install on many devices, look at the provisioning options that Greengrass supports: https://docs.aws.amazon.com/greengrass/v2/developerguide/install-greengrass-core-v2.html

After installation, use IoT Thing Groups and create Greengrass deployments to the thing group to deploy and manage all 100 devices at the same time.

Definitely just get started with a single device and make sure you understand how Greengrass is working for you before you start to scale to more than a single device.

Cheers,

Michael
