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). AWS IoT Service Tab.jpg
  • Go to EdgeDataService Tab and change connect.use-http-transport to true to use the AWS IoT Service.
  • Use HTTP Transport.jpg
  • 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

}

Total time taken to deliver a data-package to destination is timhe te from scanning vethe ry first thing data of the packet to titting acknowledge fdrom dethe stination. To elaborate if data-package send timestamp is Send Timestamp[data-package], scan timestamp of very first thing data in pathe cakka is Scan Timestamp[Thing1], time at which acknowledge received to Edge is Received Timestamp(acknowledge) then

Total time = (Send Timestamp[data-package] - Scan Timestamp[Thing1]) + (Received Timestamp[acknowledge] - Send Timestamp[data-package])
