Enabling big data & AI workloads on the object store at DBS

The big data stack has evolved over the past few years with an explosion of data frameworks, starting with MapReduce and expanding to Apache Spark and Presto. The approach to managing and storing data has evolved as well, starting from using primarily Hadoop distributed file system (HDFS) to newer, cheaper, and easier technologies like object stores. But the design of most object stores inhibits real-time big data and AI workloads running directly on them.

Vitaliy Baklikov and Dipti Borkar explore a different architecture for analytic workloads, particularly those deployed in cloud environment. Alluxio, an open-source virtual distributed file system, provides a unified data access layer for hybrid and multicloud deployments. Alluxio enables distributed compute engines like Spark or Presto or machine learning frameworks like TensorFlow to transparently access different persistent storage systems (including HDFS, S3, Azure, etc.) while actively leveraging in-memory cache to accelerate data access.

Vitaliy and Dipti dive into how DBS Bank built a modern big data analytics stack, leveraging an object store as persistent storage even for data-intensive workloads, and how it uses Alluxio to orchestrate data locality and data access for Spark workloads. In addition, deploying Alluxio to access data solves many challenges that cloud deployments bring with separated compute and storage.


Vitaliy Baklikov, DBS Bank
Vitaliy Baklikov is the senior vice president at DBS Bank, where he leads a team of architects who drive the evolution of the platform and tackle various use cases ranging from batch and stream big data processing to sophisticated machine learning workloads, with over 15 years of experience in advanced analytics and distributed architectures. He’s building a next-generation enterprise data platform for the bank that sits across private and public clouds. Previously he held various roles at startups and financial institutions across the US, UK, and Russia.
