Providing SSL certificates for SaaS customers hosted on aws

Solution 1:

You can create certificates using ACM for ELB. However, these certificates are not designed for your use case.

  • ACM: Number of domains per certificate: 10
  • ACM: Number of certificates: 100
  • ELB: Certificates per load balancer: 25

Using the above numbers as maximums you could only service 250 domains per ELB. Given that for most domain names you will want both "mydomain.com" and "*.mydomain.com" this reduces the number to 125 domain names.
