multiple public ip support in Cloud VM's


Hello,

Why is it that no cloud service providers ( AWS , Rackspace , GoGrid etc ) don't support multiple public ip's per VM's ?

Is there any explanation for this ?


Could anybody explain this in detail .


Thanks & Regards
Shankar.S

well when you're using mass cloud services, you wouldn't need separate IP's really. Why would you? Especially with cloud stuff, it's done on a huge scale with highly templated resources. What do you want multiple IP's for? one benefit of the VM approach is to keep a machines functionality clean and clear, multiple interfaces suggests multiple functions.

Hello,


What if i want to host more than one domain with different ips for each domain . I want to host them in a single vm and dont want to go for separate vm for each domain i am hosting .

A lot of small hosting providers will be thinking this way .They will be using some control panels ( cpanel or plesk ) in a vm . Then what if a cpanel account within that vm requires a separate dedicated ip ?

Thanks.

why would you need a different IP per domain? There are lots of arbitrary design decisions that conflict with what's available, but that means you should design within the limits of the technology you're using, not object to them necessarily.

Hello,


< why would you need a different IP per domain? >



1) what if one of the client requires ssl to be installed for his domain ?

2) what if one of the client just want to make sure that mails from his domain is not blocked because of some spammer using the same shared ip ? That shared ip gets blocked . So the client would like go for a dedicated ip rather than a dedicated vm .


Thanks
Shankar.S
