Kassian Wren from Cloudflare shares their experience of creating a light-up Data Center map using over 100 LEDs tied to the deployment state of each data center. The map is designed for portability and updates, debuting at SF Developer Week in February. The project utilizes Serverless technology, with Workers KV data stores used to store information about data centers and their representation on the map. Two APIs were developed around the data centers, allowing rapid deployment of serverless Workers across the world for quick access to updated data. The physical architecture of the sign will be discussed in a future post.
