Who is this presentation for?

  • Data engineers and architects



Prerequisite knowledge

  • A basic understanding of data warehousing, ETL, and cloud technologies

What you'll learn

  • Gain an overview of a PCI cloud-based data lake and an architecture utilizing batch and real-time workloads across PaaS, container orchestration, and serverless


Eoin O’Flanagan and Darragh McConville explain how NewDay built a high-performance contemporary data processing platform from the ground up on AWS. Join in to explore the company’s journey from a traditional legacy onsite data estate to an entirely cloud-based PCI DSS-compliant platform.

Eoin and Darragh detail the platform’s design principles, in the context of scale, security, speed of delivery, and proportional costs, share the company’s approach to maximizing security and performance while minimizing cost, and outline how it has prioritized the use of PaaS services and how it combined container orchestration, AWS Lambdas, and AWS DBaaS to minimize the use of IaaS. They also cover how it handles batch and real-time workloads with Kafka Streams and discuss the end-user tooling the company provides to its platform consumers. Along the way, you’ll discover how NewDay keeps the data of over six million credit card customers secure.
