Aws Iot Device Simulator
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.
Aws iot device simulator. Each lambda function assumes an aws identity and access management iam role with least privilege access minimum permissions necessary to perform its designated functions. The simulator connects to aws iot and publishes data as messages over mqtt. The iot device simulator includes a device simulator api which leverages amazon api gateway to invoke the solution s microservices aws lambda 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.
The simulation engine is powered by aws fargate. The management console is a salad s3 api gateway lambda and dynamodb application. You can also monitor individual widgets from the simulator or observe how backend services are processing the data. These microservices provide the business logic to perform operations on virtual devices and device types record simulation metrics and perform administration tasks.
The iot device simulator consists of a management console a simulation engine and api microservices that facilitate the functional areas of the solution. Running the aws cloudformation template. You can test the functioning of aws iot policies by making changes to your lambda execution role.
