Legacy System Challenges and Performance Issues

The client's monolithic learning management system required multiple authentications, suffered from slow synchronization (up to several hours), and exhibited poor performance (5+ minute load times). Their desktop student management application also experienced significant delays (7-10 minutes), hindering operational efficiency and user satisfaction.

About the Client

A leading training provider with 40+ years of experience, offering professional development courses, corporate training, and certification programs across multiple delivery channels.

Modernization Goals and Operational Improvements

Replace legacy monolithic systems with scalable microservices architecture
Implement unified authentication to reduce password fatigue
Reduce system response times to under 1 second
Improve employee productivity through modern web-based interfaces
Enable seamless data integration between learning and student management systems

Core System Modernization Requirements

Domain-driven microservices architecture (10+ services for users, courses, offers)
OpenID Connect single sign-on authentication
Event Bus synchronous communication framework
Elasticsearch-powered student data management
Automated data migration engine for legacy system transition

Technology Stack Requirements

React.js

Symfony 5.1

Docker

Event Bus

MySQL

Elasticsearch

PHP 8

System Integration Requirements

Existing mailing infrastructure via SMTP
Third-party authentication providers via OAuth 2.0
Legacy data repositories for migration

Performance and Scalability Expectations

Response time reduction from 5+ minutes to <0.5 seconds
30% overall performance improvement in student management
Horizontal scalability for 120k-1.5M entity capacity
High-availability architecture with Hetzner cloud integration
Comprehensive security controls with role-based access

Expected Business Transformation Outcomes

Implementation will deliver 0.4-0.5s page response times (from 5+ minutes), 30% performance gains in student management, unified system operations, enhanced course offer personalization through integrated data, and improved security with single sign-on. The microservices architecture will enable future scalability while reducing operational overhead through automated synchronization and centralized authentication.
