Suggested Answer:
Step 1: Create an Azure Blob Storage container
To prepare your Stream Analytics job to be deployed on an IoT Edge device, you need to associate the job with a container in a storage account. When you go to deploy your job, the job definition is exported to the storage container.
Step 2: Create an Azure Stream Analytics edge job and configure job definition save location
When you create an Azure Stream Analytics job to run on an IoT Edge device, it needs to be stored in a way that can be called from the device.
Step 3: Create and IoT hub and add the Azure Stream Analytics module to the IoT Hub namespace
An IoT Hub in Azure is required.
Stream Analytics accepts data incoming from several kinds of event sources including Event Hubs, IoT Hub, and Blob storage.

Step 4: Configure routes -
You are now ready to deploy the Azure Stream Analytics job on your IoT Edge device.
The routes that you declare define the flow of data through the IoT Edge device.

SAMBIT's answer is correct. When you add the Stream Analytics module to the IoT hub you must select an existing Stream Analytics job. So you must create the Stream Analytics Edge job first

From https://docs.microsoft.com/en-us/azure/stream-analytics/stream-analytics-edge: Azure Stream Analytics (ASA) on IoT Edge empowers developers to deploy near-real-time analytical intelligence closer to IoT devices so that they can unlock the full value of device-generated data. Azure Stream Analytics is designed for low latency, resiliency, efficient use of bandwidth, and compliance 1) Create a storage container (create blob container) 2) Create an ASA edge job (create edge job) 3) Setup your IoT Edge environment on your device(s) (create IoT hub) 4) Deploy ASA on your IoT Edge device(s) (configure routes)

Based on what I see, storage can be defined before or after the Edge, as long as it's defined before the input definition. However, it makes more sense to create Storage account before Hub, so it will be streamlines.

i agree, Create a storage account When you create an Azure Stream Analytics job to run on an IoT Edge device, it needs to be stored in a way that can be called from the device. You can use an existing Azure Storage account, or create a new one now. https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-deploy-stream-analytics
