Is AWS shield Standard automatically applied?

Question

We're using route53 in front of cloudfront and Application Loadbalancer.
Now, we have plan to apply AWS Shield Standard to prevent DDOS attacks.
But there is no functions on AWS Console to apply AWS Shield Standard (Only there be Advanced)

Is the AWS Shield Standard automatically set up on route53, application loadbalancer(ELB), Cloudfront distributions? 
There is no more tasks to apply AWS Shield Standard for our applications. right?
(We are also using WAF to prevent L7 layer ddos with rate-based rules)

Accepted Answer

Yes, Shield Standard is built-in to the AWS service. This means that it is applied transparently to all internet-facing AWS services.

It automatically mitigates standard Layer 3/4 attacks—no work required on the user side.
