About China Telecom Corporation Limited Zhejiang Branch
World leading telecommunications company China Telecom provides a wide range of information services including mobile, broadband and 5G internet connectivity to businesses and individuals throughout China. China Telecom Corporation Limited Zhejiang Branch (henceforth: China Telecom Zhejiang) is the division of the company responsible for activity in Zhejiang Provice.
Growing Cost and Complexity
As competition in China’s telecommunication industry heats up, providers are locked in a fierce battle for greater market share and increased customer loyalty.
For telecommunications companies like China Telecom Zhejiang, the key to future success lies in the large volumes of customer and operational data that it has collected over the years. While detail-rich data is abundant, managing this information cost effectively and mining it for fresh insights presents a series of complex technical challenges.
“Data is the lifeblood of our organization and powers key business functions including marketing and financial planning,” explains Mr. Xiaodong Chen, Deputy Manager, Enterprise Information Department, China Telecom Corporation Limited Zhejiang Branch. “And with data volumes set to increase exponentially, it’s essential that we can manage and analyze the mission-critical data supporting our businesses effectively.”
Robust, Reliable Infrastructure
To step up its analytics capabilities, China Telecom Zhejiang decided to replace a costly, low-performance set of analytics solutions and databases – including Teradata solutions – with a single, integrated relational analytics database built on Vertica from Micro Focus.
Mr. Xiaodong Chen comments, “Compared to other solutions, Vertica offered the easiest and quickest migration path from our legacy analytics systems. We were able to transfer most of our core analytics activities to Vertica in under eight months, which included reprograming thousands of scripts and rebuilding thousands of models.”
Since consolidating its analytics infrastructure with Vertica, China Telecom Zhejiang has achieved significant cost savings while also improving the performance of mission-critical reporting activities.
“We have cut the total cost of ownership of our analytics environment by 50 percent and reduced our storage infrastructure costs by 30 percent thanks to the powerful compression capabilities of Vertica,” explains Mr. Xiaodong Chen. “At the same time, we have accelerated some tasks by a factor of 50, so that some reports run in 5 minutes instead of 2 hours previously.”
“We’ve achieved these efficiency savings while also enhancing the performance of our analytics function. With Vertica we are able to meet all of our internal service level agreements on reporting – giving our teams the timely information they need to make smart strategic decisions.”
With Vertica powering its analytics function, China Telecom Zhejiang can double the amount of data points that it uses in its marketing and profiling analyses – helping the company to build a deeper understanding of customer preferences and deliver tailored customer experiences at scale.
Mr. Xiaodong Chen concludes: “By evolving our analytics capabilities with Vertica we’ve been able to improve knowledge sharing across our business, which enables us to be more responsive to our customers’ needs and stay ahead of our competitors.”
