Delivering Business Impacts at BT

Categories: General

Innovating with Hadoop

With £18 billion (about US$30 billion) in revenue in 2015, BT is one of the largest telecommunications providers in the world. For BT, the key to achieving sustainable, profitable growth in today’s competitive landscape is its ability to broaden and deepen customer relationships. To support this goal, BT is using a Cloudera enterprise data hub (EDH) to accelerate data velocity and fast-track the delivery of new offerings to its customers.

Today, BT is utilizing Cloudera and the power of Apache Hadoop to drive a number of compelling use cases including – processing and integrating BT’s customer data faster, effectively bringing together network and performance data to minimize wasted truck rolls, rolling out cybersecurity offerings and positioning BT to take advantage of the Internet of Things (IoT).

Check out this new video where Phillip Radley, Chief Data Architect at BT, delves into some of the key use cases and the business impacts that BT has been able to realize by utilizing Hadoop.

Accelerating Data Velocity

“We have over 2,000 registered business applications, and connecting any two of those is always a major cost exercise and a big undertaking. So being able to integrate that data in a single place is definitely a big reason for us choosing Hadoop.” – says Radley.

One of the first use cases BT utilized Hadoop for was to optimize their ETL processing. With nearly one billion records being compared and reconciled daily, BT’s legacy ETL platform, built on a traditional relational database, couldn’t keep up any more. It was taking more than 24 hours to process 24 hours of the data and at any given point in time, its business units were working with day-old data.

BT engaged Cloudera to install a production-ready Hadoop cluster that replaced the batch ETL application with MapReduce routines to increase their data velocity. “We are now taking 8 hours to process data that used to take 24. But, in addition to that, they’re processing five times the volume of data, so that’s a 15x improvement in throughput”- said Radley

 

Improving Network Performance & Powering IoT

BT is now utilizing Hadoop to bring together network and performance data to provide a deeper analysis of the of the network and help troubleshoot network issues, thereby minimizing wasted truck rolls. Having the ability to remotely identify network performance issues means sending fewer technicians to the field and this means big savings to the business – and over time, it certainly runs into millions.

Another key area where BT is utilizing Hadoop is to power its IoT (Internet of Things) journey with initiatives such as providing fleet vehicle analytics and telematics as a service. “One of the competitive edge features that we can offer is the ability to instrument those vehicles and collect data from them. Where we want to get to is to be able to predict faults, so we can identify a vehicle failing early” says Radley

With an RoI of 200 – 250%, just within the first year utilizing Hadoop, BT continues to innovate and unveil new and compelling use cases leveraging Cloudera Enterprise, and is now positioned to take on new projects faster at a lower cost.
