Case Study: The Weather Company achieves global, real-time scale delivering 15 billion forecasts per day with Amazon Web Services

The Weather Company - Customer Case Study

The Weather Company, owner of The Weather Channel and weather.com, delivers global weather forecasts and analytics to consumers, businesses and governments. After growing through acquisitions it was running 13 data centers with legacy Fortran-based forecasting systems that were neither cost-effective nor scalable enough to serve billions of locations and rapidly changing weather data.

The company re-architected its platform on AWS, building a cloud-native, API-driven stack using NoSQL databases (Riak, Redis, Cassandra), Amazon S3, Amazon Redshift and a three-layer forecast engine (DICast, forecast-on-demand and the SUN API), deployed across multiple regions. The new system processes terabytes of data hourly and handles 10–15 billion transactions per day (100k–150k/sec), reduced data centers from 13 to 6, accelerated product launches, enabled hundreds of thousands of external developers, and delivered measurable cost and operational savings (about $1M/year on one forecasting app).
