  • Best Practices: How To Build Scalable Data Pipelines for Machine Learning Nov 28 2018 6:00 pm UTC 60 mins
    Jorge Villamariona and Holden Ackerman, Qubole
    Data engineers today serve a wider audience than just a few years ago. Companies now need to apply machine learning (ML) techniques on their data in order to remain relevant. Among the new challenges faced by data engineers is the need to build and fill Data Lakes as well as reliably delivering complete large-volume data sets so that data scientists can train more accurate models.

    Aside from dealing with larger data volumes, these pipelines need to be flexible in order to accommodate the variety of data and the high processing velocity required by the new ML applications. Qubole addresses these challenges by providing an auto-scaling cloud-native platform to build and run these data pipelines.

    In this webinar we will cover:
    - Some of the typical challenges faced by data engineers when building pipelines for machine learning.
    - Typical uses of the various Qubole engines to address these challenges.
    - Real-world customer examples
  • Keeping Costs Under Control When Processing Big Data in the Cloud Recorded: Nov 13 2018 48 mins
    Amit Duvedi and Balaji Mohanam, Qubole
    The biggest mistake businesses make when spending on data processing services in the cloud is in assuming that cloud will lower their overall cost. While the cloud has the potential to offer better economics both in the short and long-term, the bursty nature of big data processing requires following cloud engineering best practices, such as upscaling and downscaling infrastructure and leveraging the spot market for best pricing, to realize such economics.

    Businesses also fail to appreciate the potential of runaway costs in a 100% variable cost environment, something they rarely have to worry about in a fixed cost on-premise environment. In the absence of financial governance, companies leave themselves vulnerable to cost overruns where even a single rogue query can result in tens of thousands of dollars in unbudgeted spend.

    In this webinar you’ll learn how to:

    - Identify areas of cost optimization to drive maximum performance for the lowest TCO
    - Monitor total costs at the application, user, and account level
    - Provide admins the ability to control and design the infrastructure spend
    - Automatically optimize clusters for lower infrastructure spend based on custom-defined parameters

  • Modern Data Engineering and The Rise of Apache Airflow Recorded: Sep 11 2018 48 mins
    Prateek Shrivastava, Principal Product Manager, Qubole
    Storage and compute are cheaper than ever. As a result, data engineering is undergoing a generational shift and is no longer defined by star-schema modeling techniques on data warehouses. Further, downstream operations are not just BI reporting and now include emerging use-cases such as data science. This means that modern day ETL tools should be dynamic, scalable, and extensible enough to handle complex business logic.

    Airflow provides that level of abstraction today’s Data Engineers need. The Qubole Data Platform provides single-click deployment of Apache Airflow, automates cluster and configuration management, and includes dashboards to visualize the Airflow Directed Acyclic Graphs (DAGs).

    In this webinar we will cover:
    - A brief Introduction to Apache Airflow and its optimal use cases
    - How to remove the complexity of spinning up and managing the Airflow cluster

  • Deep Learning with TensorFlow on Qubole Recorded: Sep 4 2018 43 mins
    Piero Cinquegrana, Sr. Data Science Product Manager, Qubole
    Deep learning works on large volumes of unstructured data such as human speech, text, and images to enable powerful use cases such as speech-to-text transcription, voice identification, image classification, facial or object recognition, analysis of sentiment or intent from text, and many more. In the last few years, TensorFlow has become a very popular deep learning framework for image recognition and speech detection use cases.

    All deep learning methods, including TensorFlow, require large volumes of data to train the model. Today, the most significant challenge in deep learning is the ever-increasing training time — as models get more complicated, the size of training data continues to increase. In order to address this challenge, cloud providers have launched instance types with many graphics processing units (GPUs) in a single node. However, using all of the GPUs in a single training job is not trivial. Qubole’s TensorFlow engine has been built to run on distributed Graphics Processing Units (GPUs) on Amazon Web Services.

    In this webinar we will:

    - Discuss how Qubole has achieved single-node, multi-GPU parallelization using native Tensorflow and Keras with Tensorflow as a backend.
    - Present results from our studies that show how training time varies with the number of GPUs in the cluster.
    - Run through a demo of a TensorFlow use case on Qubole.

  • Speed to Value: How To Justify Your Big Data Investments Recorded: Aug 15 2018 55 mins
    Amit Duvedi, VP of Business Value Engineering, Qubole
    Every investment in big data, whether people or technology, should be measured by how quickly it generates value for the business. While big data uses cases may vary, the need to prioritize investments, control costs and measure impact is universal.

    Like most CTOs, CIOs, VPs or Directors overseeing big data projects, you’re likely somewhere in between putting out fires and demonstrating how your big data projects are driving growth. If your focus, for example, is improving your users’ experience you need to be able to demonstrate a clear ROI in the form of higher customer retention or lifetime value.

    However, in addition to driving growth, you’re also responsible for managing costs. Here’s the rub-- if you’re successful in driving growth, your big data costs will only go up. That’s the consequence of successful big data use cases. How then, when you have success, do you limit and manage rising cloud costs?

    In this webinar, you’ll learn:

    - How to measure business value from big data use cases
    - Typical bottlenecks that delay time to value and ways to address them
    ​- Strategies for managing rising cloud and people costs
    - How best-in-class companies are generating value from big data use cases while also managing their costs
  • Moving Big Data To The Cloud? Here’s Why You Need A Cloud-Native Data Platform Recorded: Jul 27 2018 29 mins
    Matheen Raza and Kevin Blaisdell from Qubole
    Cloud service models have become the new norm for enterprise deployments in almost every category — and big data is no exception. As the volume, variety, and velocity of data increase exponentially, the cloud offers a more efficient and cost-effective option for managing the unpredictable and bursty workloads associated with big data compared to traditional on-premises data centers.

    Organizations looking to scale their big data projects and implement a data-driven business culture can do so with greater ease on the cloud. However, adopting a cloud deployment model requires a cloud-first re-architecture and a platform approach rather than a simple lift and shift of data applications and pipelines.
