Nokia's Big Data Ecosystem: Hadoop, Teradata, Oracle, MySQL

Nokia's big data ecosystem consists of a centralized, petabyte-scale Hadoop cluster that is interconnected with a 100-TB Teradata enterprise data warehouse (EDW), numerous Oracle and MySQL data marts, and visualization technologies that allow Nokia's 60,000+ users around the world tap into the massive data store. Multi-structured data is constantly being streamed into Hadoop from the relational systems, and hundreds of thousands of Scribe processes run every day to move data from, for example, servers in Singapore to a Hadoop cluster in the UK. Nokia is also a big user of Apache Sqoop and Apache HBase.
