Case Study: Leading technology-enabled, data-driven Customer Experience Management (CXM) company achieves sub-second, at-scale audience building and cloud modernization on AWS with Grid Dynamics

Advantages of a Next Generation Customer Data Platform for a Top Tier Marketing Agency on AWS

Leading Technology Enabled, Data Driven Customer Experience Management (CXM) Company faced an aging on‑premises stack (MS SQL, SharePoint) that couldn’t scale or meet sub‑second SLAs for ad‑hoc audience building, real‑time batching and regionally compliant data processing across the US population. Grid Dynamics was engaged to modernize the platform, replacing disk‑bound workflows with an in‑memory architecture (Apache Ignite) and cloud services on AWS to meet strict performance, scalability and security requirements.

Grid Dynamics implemented an Apache Ignite in‑memory data grid on AWS EC2 Auto Scaling alongside Elastic Beanstalk, Cognito, DynamoDB, S3 and SQS to serve APIs and integrations. The new solution processes 300+ million person objects (1.5+ TB in memory), supports 10k+ attributes per person, delivers filtering and statistics in <1 second, and achieves single‑node failover in under five minutes—enabling the agency to build precise audiences, reduce ad spend waste, and scale globally. Grid Dynamics’ work produced measurable performance and operational improvements that unlocked new business value.
