This article will show you how to get started with the Azure MedTech service in the [Azure Health Data Services](../healthcare-apis-overview.md). There are six steps you need to follow to be able to deploy and process MedTech service to ingest health data from a medical device using Azure Event Hubs service, persist the data to Azure Fast Healthcare Interoperability Resources (FHIR®) service as Observation resources, and link FHIR service Observations to patient and device resources. This article provides an architecture overview to help you follow the six steps of the implementation process.

The following diagram outlines the basic architectural path that enables the MedTech service to receive data from a medical device and send it to the FHIR service. This diagram shows how the six-step implementation process is divided into three key development stages: deployment, post-deployment, and data processing.

You must first create a resource group to contain the deployed instances of a workspace, Event Hubs service, FHIR service, and MedTech service. A [workspace](../workspace-overview.md) is required as a container for the Azure Health Data Services. After you create a workspace from the [Azure portal](../healthcare-apis-quickstart.md), a FHIR service and MedTech service can be deployed to the workspace.

### Provision an Event Hubs instance to a namespace
6565

6666
In order to provision an Event Hubs service, an Event Hubs namespace must first be provisioned, because Event Hubs namespaces are logical containers for event hubs. Namespace must be associated with a resource. The event hub and namespace need to be provisioned in the same Azure subscription. For more information, see [Event Hubs](../../event-hubs/event-hubs-create.md).
6767

68-
Once an event hub is provisioned, you must give permission to the event hub to read data from the device. Then, MedTech service can retrieve data from the event hub using a [system-assigned managed identity](../../active-directory/managed-identities-azure-resources/overview.md). This system-assigned managed identity is assigned the **Azure Event Hubs Data Receiver** role. For more information on how to assign access to the MedTech service from an Event Hubs service instance, see [Granting access to the device message event hub](deploy-iot-connector-in-azure.md#granting-access-to-the-device-message-event-hub).

When you complete the final [deployment procedure](deploy-06-new-deploy.md) and don't get any errors, you must link MedTech service to an Event Hubs and the FHIR service. This will enable a connection from MedTech service to an Event Hubs instance and the FHIR service, so that data can flow smoothly from device to FHIR Observation. In order to do this, the Event Hubs instance for device message flow must be granted access via role assignment, so MedTech service can receive Event Hubs data. You must also grant access to The FHIR service via role assignments in order for MedTech to receive the data. There are two parts of the process to connect to required services.
