: Boosting Business Returns with Faster and Smarter Data Lakes

: Boosting Business Returns with Faster and Smarter Data Lakes Empower data quality, security, governance and transformation with proven template-driven approaches By Matt Hutton Director R&D, Think Big, A Teradata Company

Executive Summary Over the past several years, organizations building Hadoop-enabled data lakes have often struggled with the challenges that come with custom engineering open source solutions. Most organizations in this position are willing to absorb the pain of early adoption for the promise of big data insights. However, when data is lodged in silos, locked-down due to security and governance access or bogged down by software release cycles, big data programs cannot deliver business value. To realize the value in organizational data, it is imperative that organizations align forces, choosing the right data lake approach to support business strategy and growth. That s why in February 2017 Think Big introduced Kylo, a next generation open source data lake management software platform. Kylo has been built on years of global expertise involving over 150 successful engagements in leading financial services, retail, telecoms, manufacturing and insurance companies to name a few. Kylo provides automated data pipelines in weeks, rather than months incorporating data quality, security, governance, operational monitoring and alerting, data preparation and profiling as well as user data access. At Discover Financial Services, we are focused on leveraging leading-edge technology that helps us quickly bring products to market while providing exceptional customer service. Kylo has a unique framework that has the potential to accelerate development and value on new data sources that leverage Apache NiFi, said Ka Tang, Director, Enterprise Data Architecture, Discover. He adds: Kylo provides an opportunity to leverage open source innovations while allowing the opportunity to give back to the open source community. Kylo is a dedicated open source data lake software with a difference; it can deliver a scalable data lake at a fraction of the multi-million dollar cost of custom engineered data lake projects while making high-quality data quickly and easily available to business as well as non-technical users.

The Power of Kylo : Overview and Benefits Kylo is an extensible data lake management software platform framework designed to accelerate big data programs, enabling users across all departments to access data easily. Kylo is a 100% open source solution, freeing your organization from costly vendor lock-ins and allowing for continued innovation and functionality extensions as provided by an open source community model. Traditional Approach With Kylo Data Ingest Weeks Minutes Validation Rules Weeks Minutes Data Profiling Weeks Automatic Data Discovery Months Seconds Figure 1. Traditional vs. Kylo Approach The Five-Tiered Data Swamp Challenge: How Kylo Can Help Having worked with more than 150 projects over the past several years, there are five common scenarios that Think Big come across time and time again. In our experience, data lakes can be: 1. Expensive and Labor Intensive - Building a custom engineered data lake and closing gaps using lowlevel platforms within the Hadoop ecosystem is a multi-year effort. Kylo builds on Hadoop, but fills the gaps to enable a fully functional data lake often in just a multi-week engagement. 2. Lacking Features to Excite and Enable Business Users - In dealing with data lakes bespoke to enterprise needs, IT departments often spend extensive budget building a huge team who spend months or years building a data lake and ingesting data without really consulting the businesses about use cases. Kylo helps to move away from that because enterprises can quickly get to building the features that excite the business and solve real problems. 3. Lacking Governance and Security - Companies often don t have the experience, capability or skills to fully enable the governance and security they need to safely and productively maintain a data lake. Kylo helps to make security and governance a key part of the creation process, whilst leveraging integration with open source options such as Ranger and Sentry. 4. Devolving Data over Time without Data Quality Control - Data in data lakes that have been custom engineered tends to devolve over time. Automated data refresh and quality assurance are key. Using Kylo, SLAs can also be tied to data confidence, with alerts connected to any downgrade in data quality. 5. Lacking Self-Service Capabilities and Suffering Slow Release Cycles - Unfortunately, building a full self-service capability for non-technical users of data lakes is extremely costly and difficult because of the amount of engineering around the user interface that has to be built in order to make it easy use. Kylo s self-service UI bypasses this problem, making it easy for non-technical users to get to the data quickly. No coding required. Think Big has developed Kylo to help make data departments quickly available to your business, ensuring users can easily query, wrangle and analyse data using its intuitive graphic user interface and dashboard. Kylo s operations management monitors the health of data feeds measuring quality, performance, and even service levels, ultimately delivering data confidence to users. It therefore frees your data lake engineering team to work on business-critical, value-add focused projects. As a result, organizations can build, manage and govern disparate datasets faster and more efficiently, saving millions while accelerating speed to market. 3 : Boosting Business Returns with Faster and Smarter Data Lakes

Kylo - The 3-Step Journey 4 : Boosting Business Returns with Faster and Smarter Data Lakes

Ingest - There are many tools that ingest batch data, but few that work to ingest streaming or real-time data. Kylo supports a mixture of both. In fact, you can have data sources that come from a streamed source into Kylo before going to a batched source, and then back to streaming. 1. Prepare - Kylo helps companies wrangle with data sources, pulling apart and understanding their data better. Kylo s Ingest and Prepare stages feature UI-guided feed creation as shown below. Users can take full advantage of Kylo s unique UI, as well as its data protection, cleanse, validation and profiling functionality to build data sources. Kylo makes building data sources for business users easier than ever before. Once data is ingested, Kylo features a visual SQL builder and a spreadsheet-like interface, exposing 180+ transformation features to help data analysts wrangle data before they publish and schedule their own feeds. From a business perspective, this means that big data programs will run faster and more smoothly, and that business end users will be able to find and model data to suit their needs easily and quickly. 2. Discover - once your data has been ingested and cleansed, analysts and data scientists can begin to search and find what data is available to them. Kylo makes this data discovery simple, allowing users to build queries to access the data to build data products that support analysis. Using Kylo, data discovery becomes quick and simple with Google-like search functionality against both data and metadata. It allows users to quickly scan the schema catalogue for relevant resources. Kylo metadata entities can be enriched with useful and extensible business metadata.
