Case Study: China Telecom Zhejiang achieves 50% lower TCO and 50x faster reporting to deliver personalized services with OpenText Vertica

Harnessing the power of data with Vertica to provide personalized services for tens of millions of customers

China Telecom Corporation Limited Zhejiang Branch is the regional arm of a leading Chinese telecommunications provider serving tens of millions of mobile and broadband customers. Faced with siloed legacy systems, rising infrastructure complexity and costs, and overnight reports that overran business hours, the company needed a scalable analytics platform to analyze large volumes of customer and operational data and deliver personalized services at scale.

China Telecom Zhejiang consolidated its analytics on Micro Focus Vertica, migrating core workloads in under eight months and replacing multiple legacy solutions. The move delivered major efficiencies—50% lower total cost of ownership, 30% reduced storage costs via compression, and up to 50× faster reporting (turning some 2‑hour jobs into 5‑minute reports)—while enabling richer customer profiling and faster, more informed decision-making.
