Assigning Static IP Address to AWS Load Balancer

Question

How can I assign a static IP address to a ELB. Seems like I cannot.

Some articles online asks to create a Route 53 record but this requires changing CNAME of domain which also redirect email traffic. I just want to change A record not CNAME.

Some articles also mention that I can use a EC2 instance as a reverse proxy. But will a single proxy be able to handle a lot of traffic?

Any solution for this?

AWS now allows static IPs with Network Load Balancer. You can assign one IP address per availability zone as per the AWS blog post.

The Application load balancer and Classic Load balancer don't support the static IPs. Although you can try using CNAME that points to the ELB hostname.

my-app.mycompany.com -> MyDomainELB-918273645.us-east-1.elb.amazonaws.com

This can allow you to integrate your application behind the ELB within your domain.
