Most EdTech platforms share the similar infrastructure headache. Admission season hits. Traffic spikes. EC2 scales slowly, costs balloon, then idles for weeks. One platform was paying for that cycle repeatedly; WAF, CloudFront, multi-region EC2, all over-provisioned for peaks they couldn't predict. We moved critical workloads from EC2 → ECS. The difference: • Container-level autoscaling = faster, cheaper scale-up • Smarter resource packing = less idle compute • Tuned WAF rules instead of blanket CAPTCHA • Optimized CloudFront caching to reduce origin load Outcome: 21% lower infra cost. 2.5x faster scale during traffic spikes. Better bot mitigation without frustrating real students. The rule to follow: if your traffic is seasonal or event-driven (exams, admissions, live classes); ECS usually wins. If utilization stays above 70–80% consistently, EC2 still earns its place. Still running burst traffic on EC2? Worth a second look 🔍. #AWS #ECS #EdTech #CloudCosts #FinOps #DevOps
