Case Study: WeatherRisk reduces IT costs by 40% and accelerates weather forecasting with Amazon Web Services (AWS)

WeatherRisk - Customer Case Study

WeatherRisk is Taiwan’s leading weather-forecasting provider for government agencies and more than 200 enterprise customers, delivering high-precision forecasts and broadcast-ready content. Its on-premises data center struggled with massive incoming meteorological feeds (e.g., up to 150 GB/day from a Japanese satellite and regular multi‑GB feeds from a U.S. provider), limited storage that constrained retention to 12 months instead of the desired 10 years, and growing procurement, power and management overheads that hindered agility.

WeatherRisk migrated its entire infrastructure to AWS with partner CKmates, ingesting data into Amazon S3 and processing it via AWS Lambda and EC2, with Glacier for long-term storage and CloudFront/RDS for web delivery. The move cut IT costs by about 40%, halved development times, enabled 10‑year data retention, sped U.S. data downloads from days to minutes and reduced satellite image generation from 15 minutes to 15 seconds—allowing faster innovation and easier scale into new markets.
