The IoT team at SmartSolutions Inc. is migrating their on-premises IoT platform to AWS to reduce operational overhead while maintaining performance, which includes a MongoDB cluster, an MQTT data collection app, periodic report generation jobs, and a public web application. The platform consists of the following components: a MongoDB cluster as a data store for all collected and processed IoT data; an application that uses Message Queuing Telemetry Transport (MQTT) to connect to IoT devices every 5 minutes to collect data; an application that runs jobs periodically to generate reports from the IoT data which take 120-600 seconds to finish running; a web application that runs on a web server where end users use the web application to generate reports that are accessible to the general public. Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose three.)
