Displaying Last 10 Minutes of AWS IoT Core Data on Web Dashboard using AWS Services

There are multiple ways to achieve what you are asking and all depends on the user experience and functionality you want to provide. Assuming that the last ten minutes of data should be displayed as a user opens the dashboard for the first time and then refreshed in near-real-time as new data comes in, one option would be the following:

1. Ingest data from IoT Core into Amazon Timestream
2. When the dashboard is opened it reads data from Amazon Timestream to get the last 10 minutes of data via a backend API built using API Gateway and Lambda functions
3. The dashboard subscribes to the AWS IoT Core topic(s) where the data is being published to receive the updates

As an alternative you can ingest data from AWS IoT Core into AWS IoT Sitewise and use the IoT AppKit components to visualize the data on the custom dashboard.
