Real-Time Reporting with Serverless Architecture 

Introduction

A global HR and compensation management firm relied on a legacy reporting system that was resource-intensive, manually operated, and unable to scale efficiently during peak reporting cycles. The static infrastructure caused performance bottlenecks during high-demand periods and remained underutilized during off-peak times, resulting in increased costs, delayed insights, and reduced operational agility. 

The client required a modern, elastic, and cost-efficient reporting system capable of ingesting multi-format survey data, generating real-time insights, and scaling automatically without manual intervention. 

Challenges

The legacy system presented multiple operational and technical obstacles:

 

  • Resource-heavy processing: Manual ingestion and transformation of survey data caused slow reporting cycles. 
  • Performance bottlenecks during peak periods, delaying real-time insight delivery. 
  • Underutilized infrastructure during off-peak periods, driving unnecessary costs. 
  • High maintenance burden with constant monitoring and manual interventions. 
  • Inconsistent reporting performance, making it difficult to support time-sensitive business decisions. 

The client needed a solution that could automate the data pipeline, scale elastically, and provide production-ready, real-time reporting at lower costs. 

Our Solution

We migrated the client’s legacy system to a fully serverless AWS architecture, creating a scalable, automated, and cost-efficient reporting platform:

 

  • Serverless Data Ingestion and Transformation: Leveraged AWS Lambda and Step Functions to automate multi-format survey data ingestion and transformation pipelines. 
  • Elastic Cloud Infrastructure: Designed with auto-scaling, lifecycle policies, and usage-based storage to optimize costs and performance dynamically. 
  • Real-Time Reporting and Analytics: Integrated Amazon QuickSight and Athena to provide interactive dashboards and ad-hoc reporting for instant insights. 
  • Monitoring and Optimization: Implemented CloudWatch for proactive system monitoring and automated alerting, ensuring consistent performance with minimal upkeep. 
  • Production-Ready Delivery: Achieved full deployment within 10 months, aligning with business timelines while improving scalability and operational efficiency. 

The solution transformed a rigid legacy system into a flexible, automated, and highly responsive reporting platform. 

Results
  • 40% reduction in infrastructure costs due to serverless architecture and usage-based optimization. 
  • 90% faster data ingestion, enabling near real-time reporting for decision-makers. 
  • Elastic scalability, automatically handling peak loads without manual intervention. 
  • Consistent system performance during reporting cycles, ensuring reliable insights. 
  • Minimal maintenance overhead, freeing IT resources to focus on strategic initiatives. 

The serverless architecture modernized reporting operations, reduced costs, and delivered real-time insights, enabling faster, data-driven decisions across the organization.
