Spark is a widely adopted open source framework that provides a unified interface for analytics and machine learning workloads. Alluxio, originating from the UC Berkeley AMPLab – the same lab as Spark, is an open source data orchestration platform that empowers compute frameworks like Spark by providing stateful caching to enable efficient data sharing between multiple jobs and improving resilience against job failures as well as bringing data together from many different sources, be it remote HDFS or cloud object stores.
Alluxio partnered with IBM to deliver a Spark-based solution to provide fast data analytics. With the integration of IBM Spectrum Conductor, an advanced workload and resource management platform that maximizes hardware utilization to speed results and cut infrastructure costs, Alluxio and IBM delivered a solution that powers leading telecom company’s applications to support 320 million subscribers. In this online meetup, we will present the benefits of the fast analytics stack of Spark on Alluxio and IBM and dive into a leading telecom’s use case of leveraging Spark and Alluxio to process massive amounts of mobile data.
In this online meetup, you will learn about:
- Why the leading companies are moving towards a decoupled compute and storage architecture, and the associated challenges and requirements.
- Why Spark and Alluxio together can solve the challenges and fulfill the requirements
- How leading telecom leverages Spark with Alluxio for fast data processing at scale on top of object store and HDFS
Using “zero-copy” hybrid bursting with Spark to solve capacity problems
Want to leverage your existing investments in Hadoop with your data on-premise and still benefit from the elasticity of the cloud?
Like other Hadoop users, you most likely experience very large and busy Hadoop clusters, particularly when it comes to compute capacity. Bursting HDFS data to the cloud can bring challenges – network latency impacts performance, copying data via DistCP means maintaining duplicate data, and you may have to make application changes to accomodate the use of S3.
“Zero-copy” hybrid bursting with Alluxio keeps your data on-prem and syncs data to compute in the cloud so you can expand compute capacity, particularly for ephemeral Spark jobs.
In this tech talk, we’ll discuss:
- Approaches to burst data to the cloud
- How Alluxio can enable “zero-copy” bursting of Spark workloads to cloud data services like EMR and Dataproc
- How DBS Bank uses Alluxio to solve for limited on-prem compute capacity by zero-copy bursting Spark workloads to AWS EMR
Many organizations are leveraging Hive to run big data analytics on public cloud. However, reading and writing data to S3 directly can result in slow and inconsistent performance. Alluxio is a data orchestration layer for the cloud, and in this use case it caches data for S3, ensuring high and predictable performance as well as reduced network traffic.
In this Office Hour we’ll go over:
- Bazaarvoice’s use case leveraging Apache Spark, Hive, and Alluxio on S3
- How to set up Hive with Alluxio such that Hive jobs can seamlessly read from and write to S3
- Open Session for discussion on any topics such as solving the separation of compute and storage problem, and more
The data ecosystem has heavily evolved over the past two decades. There’s been an explosion of data-driven frameworks, such as Presto, Hive, and Spark to run analytics and ETL queries and TensorFlow and PyTorch to train and serve models. On the data side, the approach to managing and storing data has evolved from HDFS to cheaper, more scalable and separated services typified by cloud stores like AWS S3. As a result, data engineering has become increasingly complex, inefficient, and hard, particularly in hybrid and cloud environments.
Haoyuan Li offers an overview of a data orchestration layer that provides a unified data access and caching layer for single cloud, hybrid, and multicloud deployments. It enables distributed compute engines like Presto, TensorFlow, and PyTorch to transparently access data from various storage systems (including S3, HDFS, and Azure) while actively leveraging an in-memory cache to accelerate data access.
ING Bank is a multinational financial services company headquartered in Amsterdam with over $1 trillion in assets. As a leading bank, we place a great emphasis on cybersecurity. One aspect of this is the Security incident and event management (SIEM), which is the process of identifying, monitoring, recording and analyzing security events or incidents within a real-time IT environment. SIEM requires our data platform to have high and consistent performance, so we use open source technologies Presto and Alluxio for fast SQL analytics in the cloud.
In this online presentation, we are going to present how ING is leveraging Presto (interactive query), Alluxio (data orchestration & acceleration), S3 (massive storage), and DC/OS (container orchestration) to build and operate our modern Security Analytics & Machine Learning platform. We will share the challenges we encountered and how we solved them. Today we run this platform in several different data centers, and we have reduced our 10+ minutes queries to under 10 seconds!
EMR has become a widely used service to run big data analytics in the public cloud. But issues around slow/inconsistent EMR performance due to S3 data lakes creates challenges for organizations.
Alluxio is a data orchestration layer for the cloud that increases performance of analytic workloads running on AWS EMR using S3 as the storage.
Join us for this webinar where we will show you how to set up EMR Spark and Hive with Alluxio so jobs can seamlessly read from and write to your S3 data lake. You’ll see the performance gains with Alluxio in your EMR/S3 stack.

Kubernetes is widely used across enterprises to orchestrate computation. And while Kubernetes helps improve flexibility and portability for computation in public/hybrid cloud environments across infrastructure providers, running data-intensive workloads can be challenging.
When it comes to efficiently moving data closer to Spark or Presto frameworks, co-locating data with these frameworks and accessing data from multiple or remote clouds is hard to do. That’s where Alluxio, an open source data orchestration platform, can help.
Alluxio enables data locality with your Spark and Presto workloads for faster performance and better data accessibility in Kubernetes. It also provides portability across storage providers.
In this on demand tech talk we’ll give a quick overview of Alluxio and the use cases it powers for Spark/Presto in Kubernetes. We’ll show you how to set up Alluxio and Spark/Presto to run in Kubernetes as well.
