title: Does all AWS EC2 instance has AWS shield by default?
body: <p>I want to protect my EC2 instance from DDos. And I found AWS has a service to protect instance called AWS Sheild</p>
  
  <p>On AWS's official website, it says <code>All AWS customers benefit from the automatic protections of AWS Shield Standard, at no additional charge... When you use AWS Shield Standard with Amazon CloudFront and Amazon Route 53, you receive comprehensive availability protection against all known infrastructure (Layer 3 and 4) attacks.</code></p>
  
  <p>It says <code>All AWS customers benefit from</code>, but it also says <code>When you use When you use AWS Shield Standard with Amazon CloudFront and Amazon Route 53</code>. So is an EC2 instance only have AWS shield when using CloudFront, or it will have AWS shield even if not using Cloudfront?</p>
