A flood monitoring agency has deployed more than 10,000 water-level monitoring Sensors.Sensors send continuous data updates, and each update is less than1 MB in size.The agency has a fleet of on-premises application servers.These servers receive updates from the sensors, convert the raw data into a human readable format, and write the results to an on-premises relational database server.Data analysts then use simple SQL queries to monitor the data.The agency wants to increase overall application availability and reduce the effort that is required to perform maintenance tasks.These maintenance tasks, which include updates and patches to the application servers, cause downtime.While an application server is down, data is lost from sensors because the remaining servers cannot handle the entire workload.The agency wants a solution that optimizes operational overhead and costs.A solutions architect recommends the use of AWS IoT Core to collect the sensor data.What else should the solutions architect recommend to meet these requirements?Read More →
