Financial services businesses care about minimizing risk and maximizing opportunity. These banks and capital markets companies use Hortonworks DataFlow (powered by Apache™ NiFi) to ingest more and different data into Hortonworks Data Platform (powered by Apache Hadoop®). Analysis of both data-at-rest and data-in-motion provides actionable intelligence on risks and opportunities. Modern Data Applications deliver that intelligence to improve operational margins and respond to events that might cause catastrophic losses.
Every day, large retail banks take thousands of applications for new checking and savings accounts. Bankers that accept these applications consult 3rd-party risk scoring services before opening an account. They can (and do) override do-not-open recommendations for applicants with poor banking histories. Many of these high-risk accounts overdraw and charge-off due to mismanagement or fraud, costing banks millions of dollars in losses. Some of this cost is passed on to the customers who responsibly manage their accounts.
Hortonworks Data Platform can store and analyze multiple data streams and help regional bank managers control new account risk in their branches. They can match banker decisions with the risk information presented at the time of decision, to control risk by sanctioning individuals, updating policies, and identifying patterns of fraud. Over time, the accumulated data informs algorithms that may detect subtle, high-risk behavior patterns unseen by the bank’s risk analysts.
Banks possess massive amounts of operational, transactional and balance data that holds information about macro-economic trends. This information can be valuable for investors and policy-makers outside of the banks, but regulations and internal policies require that these uses strictly protect the anonymity of bank customers.
Retail banks have turned to Hortonworks Data Platform as a common cross-company data lake for data from different LOBs: mortgage, consumer banking, personal credit, wholesale and treasury banking. Both internal managers and consumers in the secondary market derive value from the data. A single point of data management allows the bank to operationalize security and privacy measures such as de-identification, masking, encryption, and user authentication.
Ticker plants collect and process massive data streams on stock trades, displaying prices for traders and feeding computerized trading systems fast enough to capture opportunities in seconds. This is useful for making real-time decisions, and years of historical market data can also be stored for long-term analysis of market trends.
One Hortonworks customer re-architected its ticker plant with HDP as its cornerstone. Before Hadoop, the ticker plant was unable to hold more than ten years of trading data. Now every day gigabytes of data flow in from thousands of server log feeds. This data is queried more than thirty thousand times per second, and Apache HBase enables super-fast queries that meet the client’s SLA targets. All of this, and also a retention horizon extended beyond ten years.
Another Hortonworks customer that provides investment services processes fifteen million transactions and three hundred thousand trades every day. Because of storage limitations, the company used to archive historical trading data, which limited that data’s availability. In the near term, each day’s trading data was not available for risk analysis until after close of business. This created a window of time with unacceptable risk exposure to money laundering or rogue trading.
Now Hortonworks Data Platform accelerates the firm’s speed-to-analytics and also extends its data retention timeline. A shared data repository across multiple LOBs provides more visibility into all trading activities. The trading risk group accesses this shared data lake to processes more position, execution and balance data. They can do this analysis on data from the current workday, and it is highly available for at least five years—much longer than before.
