I have a blade web farm and all files are synchronised. Is it possible to have a single SSL certificate hosting multiple web sites across 3 servers or would I need to purchase multiple certificates for each site per server ?

HI,
ssl certificate is assigned for each domain

like if you have 2 domain , www.abc.com and www.xyz.com

then you will need 2 ssl certificate

Yup, each specific site needs its own certificate, however, it can be shared across platforms.

The answer depends on if all three websites have the same domain or not (ie, are they subdomains).

If so, a Wildcard SSL will suffice, it can be installed on multiple servers and will cater to all subdomains of a domain. However, depending on the issuer there may be restrictions for security and exposure reasons.

It is also possible to use a multiple domain certificate. Usually they are limited to 3 or 4 domains (for security and exposure reasons). However they require all domains to point to the same location. Which may not be possible in your case. Usually this is used in situations where you have 1 ip address for multiple websites and you want to use different SSL certificates.

Another option of course is to self-sign your certificates. However, depending on what you need to use them for, this may not be preferable. Though communications will be secured, your identity is not validated.

I have 3 golf sites and all will allow customers to purchase goods: holeinone.com, putter.com and powerdriver.com. The sites will all be load balanced across 3 IIS 7.0 web servers.

When customers purchase goods, could I have a single certificate across all 3 domains on 3 servers which I intend on using a single external IP adderss for the web site and the SSL site or do I still require a single external IP address for each SSL site ?

get  One certificate for different server

why dont you speak with ssl certificate provider and ask customer service,?
