In 2017, CTAC continued to deliver mission critical AWS solutions to the government by building an AWS cloud-native easy-to-use “heat map” application that provides populations estimates for Electricity Dependent devices for zip code, state(s), and national counts. This application uses EC2, S3, Lambda Edge, and CloudFront to deliver critical information in real-time. During the Hurricanes of 2017, the application was used extensively by preparedness responders to plan for and move those individuals who could have life-threatening complications without electricity for their home devices. In St. Thomas alone, 142 individuals were evacuated prior to the storm using the application.
