Case study
Telecom application migration to AWS with zero downtime and cost optimisation
For a large telecom client, cloud adoption had to be done carefully. The workloads were business-critical, and the migration had to protect service continuity while improving scalability and cost efficiency.
Challenge
The client needed to modernise critical telecom systems supporting messaging, CRM and campaign functions. These systems were core to service operations and needed a careful migration approach that would not impact customers or production performance.
What I delivered
I led the architecture and implementation of the migration to AWS, including:
- AWS migration architecture for telecom workloads
- environment and deployment design for business-critical systems
- serverless-based cost optimisation using AWS Lambda
- zero-downtime WebLogic patching and deployment automation
Business impact
- cloud migration completed for business-critical telecom workloads
- €10,000 per month in EC2 cost savings via automation
- successful zero-downtime production patching
Why this matters
This page is important for businesses evaluating cloud migration because it demonstrates the practical side of moving production systems without downtime. It combines technical depth, release risk management and cost discipline.
