This session provides a technical overview of a new-generation core IoT platform, designed and implemented by Enel in partnership with AWS IoT. The core IoT platform provides a single architecture and a common set of services that will be adopted by existing and future IoT applications across different business units at Enel. We analyze use cases with a live showcase of platform capabilities. We also demonstrate how the core platform enables Enel to build resilient and scalable business solutions by leveraging existing and leading-edge AWS services, such as the AWS IoT Device Gateway, AWS IoT Device Shadow, and AWS Greengrass.
