AWS-provided Greengrass connectors

AWS provides the following connectors that support common AWS IoT Greengrass scenarios. For more information about how connectors work, see the following documentation:

• Integrate with services and protocols using Greengrass connectors

• Get started with connectors (console) or Get started with connectors (CLI)
