Some services, like load balancer SSL termination require SSL certificates. To add a new certificate you need to fill in four fields:
Name This is a name you choose to identify the certificate in the interface. It can only contain letters, numbers, periods, and dashes.
Certificate This is the actual SSL public key or certificate file.
Private key This is the secret key associated with the certificate.
The storage of Certificates is free.
Certificates are available in all regions. They are region-specific resources and can only be assigned to items within the same region.
