CASE STUDY Nokia: Using Big Data to Bridge the Virtual & Physical Worlds Company Overview
Nokia has been in business for more than 150 years, starting with the production of paper in the 1800s and evolving into a leader in mobile and location services that connects more than 1.3 billion people today. Nokia has always transformed resources into useful products – from rubber and paper, to electronics and mobile devices – and today’s resource is data.

Nokia’s goal is to bring the world to the third phase of mobility: leveraging digital data to make it easier to navigate the physical world. To achieve this goal, Nokia needed to find a technology solution that would support the collection, storage and analysis of virtually unlimited data types and volumes.

Industry
Telecommunications

Use Case
Effective collection and use of data has become central to Nokia’s ability to understand and improve users’ experiences with their phones and other location products. “Nokia differentiates itself based on the data we have,” stated Amy O’Connor, Senior Director of Analytics at Nokia. The company leverages data processing and complex analyses in order to build maps with predictive traffic and layered elevation models, to source information about points of interest around the world, to understand the quality of phones, and more. To grow and support its extensive use of Big Data, Nokia relies on a technology ecosystem that includes a Teradata enterprise data warehouse (EDW), numerous Oracle and MySQL data marts, visualization technologies, and at its core: Hadoop. Nokia has over 100 terabytes (TB) of structured data on Teradata and petabytes (PB) of multi-structured data on the Hadoop Distributed File System (HDFS). The centralized Hadoop cluster which lies at the heart of Nokia’s infrastructure contains .5 PB of data. Nokia’s data warehouses and marts continuously stream multi-structured data into a multi-tenant Hadoop environment, allowing the company’s 60,000+ employees to access the data. Nokia runs hundreds of thousands of Scribe processes each day to efficiently move data from, for example, servers in Singapore to a Hadoop cluster in the UK data center. The company uses Sqoop to move data from HDFS to Oracle and/or Teradata. And Nokia serves data out of Hadoop through HBase.

Business Challenges before Hadoop
Prior to deploying Hadoop, numerous groups within Nokia were building application silos to accommodate their individual needs. It didn’t take long before the company realized it could derive greater value from its collective data sets if these application silos could be integrated, enabling all globally captured data to be cross-referenced for a single, comprehensive version of truth. “We were inventorying all of our applications and data sets,” O’Connor noted. “Our goal was to end up with a single data asset.” Nokia wanted to understand at a holistic level how people interact with different applications around the world, which required them to implement an infrastructure that could support daily, terabyte-scale streams of unstructured data from phones in use, services, log files, and other sources. Leveraging this data also requires complex processing and computation to be consumable and useful for a variety of uses, like gleaning market insights, or understanding collective behaviors of groups; some aggregations of that data also need to be easily migrated to more structured environments in order to leverage specific analytic tools.
