Aws Iot Device Simulator

You can test the functioning of aws iot policies by making changes to your lambda execution role.

Aws iot device simulator.

The iot device simulator includes a device simulator api which leverages amazon api gateway to invoke the solution s microservices aws lambda functions. You can also monitor individual widgets from the simulator or observe how backend services are processing the data. You can simulate many devices with the same configuration or invoke multiple lambda functions with unique configurations. Each lambda function assumes an aws identity and access management iam role with least privilege access minimum permissions necessary to perform its designated functions.

This device simulation solution enables customers to build a large fleet of virtual connected devices widgets from a user defined template and simulate those widgets publishing data at regular intervals to aws iot. It includes a link to an aws cloudformation template that launches configures and runs the aws services required to deploy this solution using aws best practices for security and availability. The iot device simulator microservices are a series of aws lambda functions that provide the business logic and data access layer for all device simulation operations. These microservices provide the business logic to perform operations on virtual devices and device types record simulation metrics and perform administration tasks.

This implementation guide discusses architectural considerations and configuration steps for deploying the iot device simulator in the amazon web services aws cloud. The simulation engine is powered by aws fargate. The management console is a salad s3 api gateway lambda and dynamodb application.
