Challenge

The IaaS-based system did not scale, released slowly, performed poorly and cost more than it should have. Global expansion was planned, and the platform could not carry it without a move to AWS and a serious modernization.

Solution

A phased AWS migration that combined architectural improvement with real-time monitoring and performance work, and brought DevOps practice, frontend and backend optimization and parallel feature development along with it.

Implementation

  • 01Architecture and migration plan revised for AWS PaaS
  • 02Phase 1 — performance and observability
  • 03Phase 2 — abstraction layers introduced, services migrated
  • 04Phase 3 — auto-scaling, reliability and long-term scalability
  • 05DevOps/SecOps/SCRUM established, with monitoring and automated testing

Business impact

Migration completed in 10 months with no disruption

Faster response times and a better user experience

Better observability and proactive incident management

Structured delivery that reduced technical debt

A platform now ready to scale globally
