Edge AWS IoT Configuration

• Setup the AWS IoT Core account and download the certificate, AmazonCA1 and private key.
• Open Cloud Services and go to the AWS IoT Service Tab.
• Edit All the Necessary fields like aws-endpoint, private key etc.
• Select AWS from the edge.data-destination dropdown menu (This determines where to send data like to datonis or aws).
• Go to EdgeDataService Tab and change connect.use-http-transport to true to use the AWS IoT Service.
• 
• Done.

AWS IoT Latency Calculation

Edge Sends a data-package to the AWS, each data-package can have multiple things data. The number of things data in a data-package can be configured through bulk_size. A data-package contains timestamp when it is ready to send whereas thing data contains individual thing scan timestamp, thing key, and data array.

Following will be the format for data :

{

"events": [

{

"thing_key": "ft26ecabad",

"timestamp": 1641561474351,

"data": {

"tag_1": 2542

},{

"thing_key": "jt77eczb2d",

"timestamp": 1641561474357,

"data": {

"tag_1": 2542

},

"data_faas_function": "",

"type": "data"

}

],

"timestamp": 1641795756303

}

Calculation : total time taken from scanning to send = (Send timestamp - Scan timestamp) + (current received timestamp) - (Send timestamp).

Scan Timestamp : timestamp under each thing object.

Send Timestamp : timestamp to the end of package.

Current Received Timestamp : the AWS timestamp when data is received on the platform.

Total time taken from scan to send data-package is the time difference between data-package timestamp and scan timestamp of very first thing data inside data package
