Uteach is an online platform that focuses on providing course creators to create and market their courses online.
The Challenge
Uteach is a multi tenant project, meaning that, it serves multiple different domains for each customer. When a DDoS attack happens one particular domain (Uteach’s client) their servers get overloaded which is impacts most of the customers.
DDoS attack on different clients were carried out regularly which overall impacted the system performance and other clients.
The Solution
- We added WAF rules to their CDN (CloudFlare) to block suspicious traffic. This helped us to get suspicious traffic at edge and avoid passing malicious traffic into origin servers
- Application was using EKS (Elastic Kubernetes Service) on origins traffic passing through ELB. We added auto scaling flexibility on that in order to scale
Outcome
There were no more daily interruptions in system functionality because of DDoS attacks.
