Real-Life Case Studies of Legacy System Integration via APIs

Martin Dejnicki

[In the fast-paced world of technology, legacy systems are often seen as a roadblock to innovation, yet they hold the core functions crucial for everyday operations.

Integrating these systems with modern applications effectively can drive significant advancements and efficiencies.

At Deploi, we excel in bridging the gap between the old and the new, transforming challenges into opportunities through the strategic use of APIs.]

The Problem: Legacy System Rigidity

Legacy systems, despite their reliability, often lack the agility of modern solutions. Many organizations struggle with these systems as they attempt to adapt to new business demands. APIs, or Application Programming Interfaces, can serve as a lifeline by enabling these veteran systems to communicate with newer applications. Here, we explore real-life case studies demonstrating the successful integration of legacy systems via APIs, each showcasing practical insights and strategies.

Case Study 1: Elevating Retail with API Connectors

Challenge: A leading retail company leveraged a legacy mainframe for inventory management. Despite its reliability, it couldn't natively integrate with their e-commerce platform, creating silos between physical and online stores.

Approach: We deployed RESTful APIs to bridge the mainframe with the online platform seamlessly, employing real-time data syncs to eliminate discrepancies in inventory data across channels.

Outcome: The API integration allowed real-time inventory updates, reducing stockouts by 40% and enhancing user experience with accurate product availability online.

Insights for Technology Leaders:

  • Real-Time Data Flow: RESTful APIs are ideal for enabling real-time synchronization, critical in retail operations.
  • Scalable Solutions: APIs offer scalability, adapting to growing data demands without significant changes to the existing infrastructure.

Case Study 2: Financial Sector's Data Renaissance

Challenge: A financial institution relied on a COBOL-based system for customer data processing. As the need for advanced analytics grew, they faced hurdles extracting actionable insights swiftly.

Approach: Our team integrated modern analytics tools using API gateways, reducing dependence on the COBOL system's processing capabilities while leveraging its robust data store.

Outcome: The integration decreased the turnaround time for generating reports by 60%, enabling faster decision-making and improved customer personalization.

Insights for Technology Leaders:

  • Leverage Robust Data Stores: APIs allow modern applications to tap into the reliable data reservoirs of legacy systems, enhancing data accessibility.
  • Advanced Analytics Integration: API gateways provide a versatile interface for integrating sophisticated analytics tools without disrupting core system operations.

Case Study 3: Modernizing Manufacturing Operations

Challenge: A global manufacturing company operated numerous legacy SCADA systems to monitor and control production. These systems isolated data from higher-level business applications, limiting strategic oversight.

Approach: Deploi introduced APIs to connect SCADA systems to a centralized dashboard, consolidating data for better visibility and operational control.

Outcome: Integration facilitated comprehensive monitoring and control capabilities, increasing production efficiency by 25% and granting management a unified view of operations.

Insights for Technology Leaders:

  • Unified Data View: APIs enable the aggregation of disparate system data, providing a holistic view that supports strategic decision-making.
  • Increased Efficiency: Connecting operational systems to business intelligence platforms can yield substantial efficiency gains.
