ore medical devices, and runs local (on-premises) applications for operators/technicians for command and control. Only AWS IoT Greengrass cores are created as Things in AWS IoT Core. Metadata for medical devices lives in DynamoDBand not in AWS IoT Core, because command and control is not allowed from the cloud. Amazon API Gateway is the single secure endpoint invoked from AWS IoT Greengrass for all API calls. APIs include device provisioning, APIs used to access AWS services and 3rdparty endpoints. 9 7 5 4 6 Streaming video from medical devices is sent to Amazon Kinesis in the AWS Cloud and persisted in the Amazon Simple Storage Service (Amazon S3)data lake. Implement data and video insights by linking with device metadata in AmazonDynamoDB. Telemetry data from devices sent by AWS IoT Greengrass to AWS IoT Core using MQTT, can be stored in a Amazon Timestreamdatastore for historical analytics. Data files generated from medical procedures directly are uploaded to AmazonS3and linked with device metadata in AmazonDynamoDB. Can be used for artificial intelligence/machine learning (AI/ML). Device Metadata Event Notifications Amazon Identity and Access Management (IAM) AuthN/AuthZ Outbound Connectivity from Device only to Greengrass Gateway Amazon DynamoDBis the central storage for device models, metadata, security certificates, and more. associated with the edge gateway to which the medical devices are connected. 10 11 12 Telemetry data sent via rules for AWS IoT Core to AWS IoT Events for complex event detection. Detected events generate alerts for customer support via Amazon SNS. Batch extract, transform, load (ETL) processing on data done using AWS Glue and curated data persisted back in AmazonS3. Amazon Athenaand AmazonQuickSightprovide business intelligence (BI)/visualization for users. 11 Machine learning models trained withAmazon S3 data for predictive analytics, computer vision, and more. 12 Small clinics and home medical devices connect to AWS using VPN or internet.
