With an IoT workload, many units and gateways join and ship totally different information sorts and with totally different schemas. Having a boundary outlined by AWS account makes it simpler to handle quotas and particular person buyer fleet wants as a result of you may set up totally different account-level insurance policies.
• Information Privateness – IoT is used globally and throughout many industries. As well as, information privateness rules fluctuate by trade and area. Having separate IoT endpoints for every tenant which might be primarily based on their necessities offers flexibility to function as a worldwide SaaS platform.
• Gadget Provisioning and Onboarding – You need to have a method to onboard units to a number of tenant endpoints with out altering the foundation system id within the subject. IoT safety finest practices recommends the provisioning of units with distinctive, cryptographic id that’s authenticated at every IoT endpoint.
  Programming and establishing the foundation id within the system sometimes happens in a managed buyer setting, similar to throughout manufacturing. It might probably take months or years for a tool to maneuver via the worldwide provide chain earlier than it’s put in within the subject. Tightly coupling the system’s id to a tenant account’s IoT endpoint throughout manufacturing creates an rigid provide chain. It additionally causes SKU fragmentation for the producers. You need to take into account that onboarding the system id to an IoT endpoint can happen later within the system’s lifecycle.

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

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

• Platform creation automation – While 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 resolve a few of the information isolation, privateness and quota administration challenges.
• Gadget provisioning and onboarding – Use a centralized onboarding service to say and route IoT units to designated tenant IoT endpoints. This helps clear up the tenant-specific system provisioning problem throughout manufacturing and late tenant binding.
