I need to secure a couple websites, and am looking for the ideal SSL solution to handle multiple domain names / multiple hosts. Here is a breakdown of my topology.
Website 1 - Self hosted IIS server. This server has multiple IP addresses (3 different ISP connections) and host names, but all point to the same exact virtual machine, aside from a replica that is stored at a remote location, but would need to be able to come online as a failover.
website1a.com - points to 220.127.116.11 (onsite IIS Server)
website1b.com - points to 18.104.22.168 (onsite IIS Server)
website1c.com - points to 22.214.171.124 (onsite IIS Server)
website1d.com - points to 126.96.36.199 (offsite backup of IIS server)
Website 2 (Wordpress) - GoDaddy VPS hosted, with Name Cheap backup website
website2.com - points to 188.8.131.52 when there is a fail over, I auto redirect the DNS for website2.com to go to NameCheap Hosting 184.108.40.206
I was thinking about purchasing a single SAN SSL that includes every domain. However, I am not sure I will be able to install that SSL on the IIS server, as well as the go-daddy and name-cheap hosting.
Looking for advise.
Thanks in advance!!
