The ESPER platform provides an automated app update solution that pushes the latest version of an app to devices as soon as they come online. The solution uses AWS Lambda and API Gateway, along with Esper's Device SDK, to determine if a more recent version of the app has been uploaded to the customer's endpoint and update the device accordingly. To implement this solution, customers can clone the provided lambda repository, modify the SAM configuration file, and deploy it to production using the SAM CLI. Once deployed, customers can trigger the update by making an HTTP POST call to the Lambda endpoint with the required payload.
