I'm running a small web application on an EC2 instance, which is accessed by a few external users. I'm looking for ways to enhance its resilience against DDoS attacks, but the sheer number of protection options from AWS feels a bit overwhelming. I've done some research, and I'm considering placing my EC2 instance behind an AWS Load Balancer to help manage Layer 3 and 4 attacks. I also learned that AWS WAF could be a good addition for guarding against Layer 7 threats.
Regarding AWS Shield, I noticed that while Shield Advanced seems to offer better protection, it might be too much for my small-scale project. I've seen mentions of using Cloudflare for DDoS protection across all layers, even with its free option, which piques my interest.
Given these insights, I'm eager to hear recommendations on the most practical and cost-effective measures I can implement for DDoS mitigation for my small application. Any advice would be greatly appreciated!

You should definitely place your EC2 behind an Autoscaling Group (ASG) and Application Load Balancer (ALB), regardless of DDoS threats. Think of the instance as temporary and set it up to be replaced easily if needed. Going with a basic AWS WAF configuration should be sufficient to start.
