My company's development team is in process of developing two sites that will have two separate domain names (let's say
bar.example), but will be hosted on a single cloud Linux/Apache server.
Do we need to purchase SSL certificates for each domain (one for
foo.example and one for
bar.example), or do we just need one for the server? And are there any specific security concerns that need to be taken in to account when using SSL in this environment?
