Having a boundary outlined by AWS account makes it simpler to handle quotas and particular person buyer fleet wants as a result of you possibly can set up completely different account-level insurance policies.
• Knowledge Privateness – IoT is used globally and throughout many industries. As well as, knowledge privateness laws range by trade and area. Having separate IoT endpoints for every tenant which can be based mostly on their necessities supplies flexibility to function as a world SaaS platform.
• Gadget Provisioning and Onboarding – You have to have a technique to onboard units to a number of tenant endpoints with out altering the basis machine identification within the area. IoT safety finest practices recommends the provisioning of units with distinctive, cryptographic identification that’s authenticated at every IoT endpoint.
  Programming and establishing the basis identification within the machine usually happens in a managed buyer setting, comparable to throughout manufacturing. It could actually take months or years for a tool to maneuver via the worldwide provide chain earlier than it’s put in within the area. Tightly coupling the machine’s identification to a tenant account’s IoT endpoint throughout manufacturing creates an rigid provide chain. It additionally causes SKU fragmentation for the producers. You have to contemplate that onboarding the machine identification to an IoT endpoint can happen later within the machine’s lifecycle.

The reference structure on this weblog addresses the above challenges, simplifies the deployment and operation, and enhances knowledge governance.

The next discusses the important thing factors within the structure (Determine 1):

• Platform creation automation – If you onboard a brand new tenant, the structure creates a brand new AWS account which establishes tenant-dedicated and region-specific AWS IoT Core endpoints. Afterward, it deploys different associated AWS companies and purposes in every new account. This automated course of helps to unravel a few of the knowledge isolation, privateness and quota administration challenges.
• Gadget provisioning and onboarding – Use a centralized onboarding service to assert and route IoT units to designated tenant IoT endpoints. This helps clear up the tenant-specific machine provisioning problem throughout manufacturing and late tenant binding.
