Data Pipeline Revolution for Environmental Services with Real-Time Processing

Introduction

This case study explores the collaboration between Tasrie IT Services and Tervita Corporation, focusing on upgrading Tervita’s data pipeline infrastructure to enhance smart mobility insights. The transformation enabled real-time processing of connected vehicle data, providing actionable insights for sustainability and efficiency improvements.

Client Background

Tervita Corporation is a leading environmental and energy services company with a mission to enhance sustainability and efficiency through smart mobility insights. Their business depends on processing vast amounts of data from connected vehicles to provide valuable insights to customers.

The company operates a large fleet of specialized vehicles equipped with sensors and tracking systems that generate continuous streams of data. This data, when properly processed and analyzed, provides critical insights into operational efficiency, environmental impact, and safety metrics.

Problem Statement

Tervita faced significant challenges with their outdated data pipeline that hindered effective processing and utilization of connected vehicle data:

Legacy Infrastructure Limitations

Data Processing Bottlenecks

• Outdated pipeline couldn’t handle data volume from connected vehicles
• Batch processing introduced significant delays
• Limited real-time insights capability
• Manual data reconciliation required

Scalability Constraints

• Fixed infrastructure couldn’t scale with growing vehicle fleet
• Peak data loads caused processing failures
• Adding new data sources required extensive manual effort
• Monolithic architecture resisted modification

Insight Delays

• Batch processing meant insights were hours or days old
• Business decisions based on outdated information
• Missed opportunities for real-time intervention
• Customer dissatisfaction with delayed reporting

Solution Provided by Tasrie IT Services

We designed and implemented a comprehensive modern data pipeline leveraging industry-leading technologies:

Technology Stack

AWS (Amazon Web Services)

Recommended for its scalability, reliability, and security. AWS provided the foundation for a cloud-native architecture that could grow with Tervita’s needs.

Debezium
