Teréga, a French gas storage and transportation company, is accelerating its energy transition by creating a mixed-energy business model that incorporates biomethane and hydrogen into traditional energy sources. The company's legacy IT infrastructure was outdated, making it challenging to onboard new customers and projects, maintain, and innovate. After researching cloud-native data historians, Teréga built its own proprietary historian, IO-Base, using InfluxDB as its foundation, which provides a high-performing, scalable, and resilient solution for handling massive time series data. The company's new historian, IO-Base, is cloud-native, secure, and user-friendly, with features such as real-time metrics creation, customizable user interfaces, and seamless integration with AWS infrastructure.
