Big Data in Core Telco

When our CMS became the target of a large-scale DDoS attack, it triggered a real-world stress test of our cloud infrastructure. From saturated load balancers and 100% CPU utilization to emergency mitigation measures, this incident challenged our resilience. By rapidly implementing AWS CloudFront, AWS WAF, and a secure edge-based protection model, we successfully stabilized the system and prevented further disruption. A follow-up attack confirmed the effectiveness of the new architecture, demonstrating how proactive security design and strong collaboration ensure service continuity and long-term resilience.
