AWS IoT Edge Management
1. Confidential Customized for Proof of Concept Version 1.0
Aws IoT Edge
Management
Greengrass and Core solution By Avinash Patil and Aditya Dubey
2. Overview
★ Effective use of IoT with integrated solution with AWS Greengrass
★ Use of Lambda function which containerized for Greengrass connection to gather data from IoT Devices
★ Use of S3 for data storage for sensor and machine data
★ DevOps provisioning of IoT environment using Python Scripts and Cloudformation
★ Use of AWS Managed Databases for Synchronizing device data and events
★ Schema Design for Handling IoT Data with tables
3. Problems to solve
1
IoT Device manager Management
2
AWS Cloudwatch,S3 or Firehose, SNS type
solution for failure notification
3
AWS IoT GreenGrass data retrieval and
send to Inhouse IoT Devices
4
Manage connection between IoT Edge
devices with AWS Greengrass
4. Implement aws greengrass
★ Install the AWS IoT Greengrass Core Software or SDK for python in the hardware(eg: Raspberry pi)
★ Configures your cloud-based resources.
○ Generate the device certificate.
○ Configure greengrass group.
○ Configure rule engine to maintain a connection and process the data to lambda function or other aws service.
★ Deploy greengrass group to production with lambda.
6. Create and package a lambda function
★ Create lambda function by using AWS IoT Greengrass Core SDK for Python3.x
★ Create a deployment package with all dependencies and upload it to the aws lambda console.
★ Use the lambda action to store data into S3 or DynamoDB.
Configure the Lambda Function for AWS IoT Greengrass
★ Use the AWS IoT console to add the Lambda function to your Greengrass group.
★ Configure group-specific settings for the Lambda function.
★ Add a subscription to the group that allows the Lambda function to publish MQTT messages to AWS IoT.
★ Configure local log settings for the group.
★ Verify the Lambda Function whether it is running on the core device by using aws iot core console.
7. Messaging
★ Create MQTT Pub/Sub broker for communication.
★ Apply filter to MQTT topic for filtering the messages.
★ Create subscription to access the messages for device
activity or state.
★ Use the MQTT broker to send/receive the failure
message of a device.
8. Device Shadow
A JSON document that represents the device state of
your devices and lambdas. It sync the stored data to
cloud or our own server.
★ Create a lambda to trigger S3 service to store the device
info in S3 database.
★ Create a rest API call to communicate with our own
Server.
★ Create a lambda with different action to store shadow
data or other info to our server through the API call.
9. Security
★ Create root CA certificate with sigv4 credentials
separately for production.
★ Local CA certificate should be different from
production.
★ Create and maintain separate policies and roles for
different IAM users as per the requirement.
10. IoT management with AWS Solution
Propose a solution and integrate existing
IoT devices to have on device analysis
and core management.
