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.
