Modernizing a Monolithic Parking Platform with Scalable Microservices Architecture

A leading parking solutions provider faced performance bottlenecks and limited scalability due to its legacy monolithic application architecture. As demand grew—especially during peak traffic periods—the system struggled to scale, delayed feature rollouts, and incurred frequent downtimes during updates.
To overcome these challenges, ekSource designed and executed a phased migration to a modern microservices-based architecture, enabling independent service deployment, faster time-to-market, and improved system resilience. The transition allowed the parking provider to scale specific services independently, reduce system downtime, and adopt newer technologies for enhanced performance and reliability.

Business Challenge

The parking company operated a high-traffic consumer platform for booking, managing, and paying for parking services. However, its monolithic architecture became increasingly unsustainable as the platform grew.
  • Scalability Bottlenecks: During high-demand periods (e.g., holidays, events), the system couldn’t scale efficiently, impacting user experience and causing system slowdowns.
  • Slow Feature Deployment: The tight coupling of services in the monolith meant any new feature deployment required full-system testing, increasing lead time and operational risk.
  • Maintenance Overhead: Bug fixes and minor updates affected the entire application, resulting in frequent downtimes and increased QA cycles.
  • Technology Constraints: The architecture restricted the adoption of new, service-specific technologies, stifling innovation and performance optimization in individual modules.

Solution

To address these limitations, ekSource led a migration from monolith to microservices, allowing the platform to be modular, scalable, and resilient.
Microservices Architecture Implementation
The system was decomposed into independent, function-specific microservices, enabling parallel development, deployment, and scaling.
Key Microservices Developed:
  • User Service: Manages authentication, user profiles, and access control
  • Product Service: Handles product catalog, inventory, pricing, and search functions
  • Order Service: Processes parking orders, reservations, payments, and confirmations
  • Cart Service: Supports shopping cart and checkout workflows for parking selections
  • Notification Service: Manages email and push notifications for confirmations, reminders, and alerts

Implementation Strategy

Technology Stack
  • Backend: .NET Core for scalable, high-performance microservices
  • Frontend: React.js for responsive, modern user interfaces
  • Databases: MySQL for structured transactional data, Redis for fast caching
  • Messaging: AWS SQS for event-driven, asynchronous communication between services
  • Deployment: Docker containers orchestrated via AWS ECS Fargate for serverless scaling and management
Communication Model:
  • Synchronous: REST APIs managed via AWS API Gateway
  • Asynchronous: Event-driven triggers through AWS SQS queues Security & Access Control:
  • JWT-based authentication across services
  • API Gateway enforced rate limiting and authentication policies for secure external access
CI/CD & DevOps:
  • GitHub Actions for automated testing and build validation
  • AWS CodePipeline for continuous integration and deployment, supporting independent deployment of microservices

Benefits

The migration to microservices architecture yielded significant improvements in performance, agility, and scalability:
  • Improved Scalability: Services could now be scaled independently, ensuring optimal performance during peak usage periods.
  • Faster Time-to-Market: New features were developed and deployed independently, reducing release cycles and increasing responsiveness to market needs.
  • Reduced Downtime & Maintenance: Targeted bug fixes and updates minimized disruptions, improving platform stability and uptime.
  • Technology Flexibility: Teams could now leverage service-specific technologies for performance optimization and innovation.
  • Cost Optimization: AWS ECS Fargate enabled serverless container orchestration, reducing infrastructure management overhead and costs.
By modernizing its legacy system into a microservices architecture, the parking solutions provider achieved greater system agility, scalability, and operational efficiency. The platform is now resilient to peak loads, faster in rolling out new features, and better positioned for future growth and innovation.
