3 The fundamentals of in the era of big data Introduction Organizations are eager to harness the power of big data. But as new big data opportunities emerge, ensuring that information is trusted and protected becomes exponentially more difficult. If these challenges are not addressed directly, end users may lose confidence in the insights generated from their data which can leave them unable to act on new opportunities or address threats. The tremendous volume, variety and velocity of big data means that the old manual methods of discovering, governing and correcting data are no longer feasible. Organizations need to automate information integration and governance from the start. By automating information integration and governance and employing it at the point of data creation and throughout its lifecycle, organizations can help protect information and improve the accuracy of big data insights. 3 1 Introduction 2 Big data, big impact: Putting into action

4 The fundamentals of in the era of big data Information integration and governance solutions must become a natural part of big data projects. They must support automated discovery and profiling and they must facilitate an understanding of diverse data sets to provide the complete context required to make informed decisions. They must be agile enough to accommodate a wide variety of data and seamlessly integrate with diverse technologies, from data marts to Apache Hadoop systems. Plus, they must discover, protect and monitor sensitive information across its lifecycle as part of big data applications. Understanding the context of data and being able to extract the precise information necessary to meet a business objective is key to utilizing big data to the fullest. Managing the so that data is accurate, is appropriately used and is correctly stored to meet the required service levels and retention needs has wide-ranging benefits. These benefits include risk reduction, performance improvements and preventing an overload of useless information. This e-book explores the challenges of managing big data, best practices for enterprise-scale and how IBM InfoSphere Optim solutions incorporate a comprehensive range of information integration and governance capabilities that enable companies to properly manage data over its lifetime. 4 1 Introduction 2 Big data, big impact: Putting into action

5 The fundamentals of in the era of big data Big data, big impact: Without effective, the increasing volume, variety and velocity of big data can reduce performance, increase margins and amplify risks. Performance and time-to-market As more users execute more queries on larger data volumes, slow response times and degraded application performance become major issues. If left unchecked, continued data growth will stretch resources beyond capacity and negatively impact response time for critical queries and reporting processes. These problems can affect production environments and hamper upgrades, migrations and disaster recovery efforts. Implementing intelligent data of historical, dormant data is essential for avoiding these potentially business-halting issues. Rapid data growth also makes testing more difficult. As data warehouses and big data environments grow to petabytes or more, testing processes are taxed by having to cull data for their specific needs. The results include longer test cycles, slower time-to-market and fewer defects identified in advance of release. Speeding up testing workflows and delivery of data warehouses requires organizations to automate the creation of realistic rightsized test data while keeping appropriate security measures in place. Margins Exponential data growth also can drive up infrastructure and operational costs, often consuming most of an organization s data warehousing or big data budget. Rising data volumes require more capacity, and organizations often must buy more hardware and spend more money to maintain, monitor and administer their expanding infrastructure. Large data warehouses and big data environments generally require bigger servers, appliances and testing environments, which can also increase software licensing costs for the database and database tooling, not to mention labor, power and legal costs. 5 Putting into action

6 The fundamentals of in the era of big data Risks Following the let s keep it in case someone needs it later mandate, many organizations already keep too much historical data. According to the CGOC 2012 Summit Survey, 69 percent of data has no value. Opening the doors to excessive storage and retention only exacerbates the situation. At the same time, organizations must ensure the privacy and security of the growing volumes of confidential information. Government and industry regulations from around the world, such as the Health Insurance Portability and Accountability Act (HIPAA), the Personal Information Protection and Electronic Documents Act (PIPEDA) and the Payment Card Industry Data Security Standard (PCI DSS) require organizations to protect personal information no matter where it lives even in test and development environments. Data breaches and attacks risk negative consumer sentiment 75% of IT risks impact customer satisfaction and brand reputation 75 % 43 % 43% are increasing focus on reputational risk because of growth in emerging technologies such as social media Maintaining compliance with data retention regulations, protecting privacy and archiving data are not just legal matters they are essential for sustaining customer satisfaction and brand reputation. In recent IBM surveys, respondents indicate that data theft/ cybercrime is the number-one threat to a company s reputation a greater threat than system failures. Sixty-four percent of respondents say their company will be focusing more on managing and protecting their reputation than they did five years ago. 1 Source: Insights from the 2012 Global Reputational Risk and IT Study. 6 Putting into action

7 The fundamentals of in the era of big data The danger of treating a backup as an archive Many organizations are confused about the difference between archiving and backing up data. Archiving preserves data, providing a long-term repository of information that can be used by litigation and audit teams. By contrast, backing up data involves copying production data and moving it to another environment to enable disaster recovery and the restoration of deleted files. Backups are often retained for a short time, until a fresh backup replaces the existing backup. Archiving complements backups by removing old, redundant and infrequently accessed data from a system and by reducing the size of databases and their backups. Approximately 75 percent of the data stored is typically inactive, rarely accessed by any user, process or application. An estimated 90 percent of all data access requests are serviced by new data usually data that is less than a year old. 2 With an effective archiving strategy, organizations can protect old data and comply with data retention rules while reducing costs and enhancing system performance. In an attempt to meet archiving needs, some organizations simply back up data to a Hadoop environment. But this kind of backup will not ensure that data will be fully protected or remain query-able, the way a true archive would. With an effective data lifecycle solution, companies can create an archive that protects data, meets compliance standards, and supports queries and reporting. An emerging trend is for organizations to use Hadoop as a lower-cost storage alternative for archives. 7 Putting into action

8 The fundamentals of in the era of big data Best practices: Putting into action The stretches through multiple phases as data is created, used, shared, updated, stored and eventually archived or defensively disposed. Data lifecycle plays an especially key role in three of these phases of data s existence: archiving, test data and data masking. The entire (shown as the grey circle) benefits from good governance, but capabilities that focus on the use, share and archive steps have wide-ranging benefits for cost reduction and efficiency gains. Where tasks fall in the Archiving Store /retain Dispose Archive Update Test data Create Use Share Data masking Archiving Retention policies are designed to keep important data elements for reference and for future use while deleting data that is no longer necessary to support the legal needs of an organization. Effective includes the intelligence not only to archive data in its full context, which may include information across dozens of databases, but also to archive it based on specific parameters or business rules, such as the age of the data. It can also help storage administrators develop a tiered and automated storage strategy to archive dormant data in a data warehouse, thereby improving overall warehouse performance. 8 Putting into action

9 The fundamentals of in the era of big data Enterprise information 69% Everything else 1% Subject to legal hold 25% Has business utility 31% 5% Regulatory record keeping Many organizations hope that big data will provide a large, centralized lake of data, but in many cases, it becomes a data swamp full of unreliable information. Many organizations envision big data as a large, pristine, centralized data lake. But a data lake can quickly turn into a data swamp when data is poorly managed and controlled. By setting up an intelligent data lifecycle strategy and archiving to inexpensive storage, you can avoid turning your big data environment into a dumping ground. Test data In development, testers must automate the creation of realistic, rightsized data sources that mirror the behaviors of existing production databases. To ensure that queries can be run easily and accurately, they must create a subset of actual production data and reproduce actual conditions to help identify defects or problems as early as possible in the testing cycle. The tremendous size of big data systems creates challenges for testers. There is a greater need to speed delivery of big data applications, requiring organizations to create realistic, rightsized, masked test data for testing those applications for performance and functionality. Testers also need ways to generate test data sets that facilitate realistic functional and performance testing. Because production data contains information that may identify customers, organizations must mask that information in test environments to maintain compliance and privacy. 9 Putting into action

10 The fundamentals of in the era of big data Applying data masking techniques to the test data means testers use realisticlooking, but fictional data no actual sensitive data is revealed. Application developers can also use test data technologies to easily access and refresh test data, which speeds the testing and delivery of the new data source. Organizations also need ways to mask certain sensitive data, such as credit card and phone numbers. While testing their big data environments, they must mask sensitive data from unauthorized users, even though those users might be authorized to see the data in aggregate. For example, a pharmaceutical company that is testing its data warehouse environment might mask Social Security numbers and dates of birth but not patients ages and other demographic information. Masking certain data this way satisfies corporate and industry regulations by removing identifiable information, while still maintaining business context and referential integrity for testing in nonproduction environments.

14 The fundamentals of in the era of big data The value of test data at a US insurance company With 42 high-volume back-end systems needed to generate a full end-to-end system test, a US insurance company could not confidently launch new features. Testing in production was becoming the norm. In fact, claims could not be processed in certain states because of application defects that the teams skipped over during the testing process. IT was consuming an increasing number of resources yet application quality was declining rapidly. After implementing a process to govern test data, the insurance company reduced the costs of testing by USD400,000 per year. Today, the company can easily refresh 42 test systems from across the organization in record time while finding defects in advance. The business value from implementing test data included: $500, percent fewer untested scenarios 44 % 41 % Cost savings of approximately USD500,000 per year 41 percent less labor required over 12 months 14 Putting into action
