Windows Azure VM and SQL for hosting websites? RRS feed

  • Question

  • I have a couple of questions about how Azure VM's work.

    Long story short we were going to rebuild our ageing IIS box that lives in our DMZ but looking at Azure on paper it seems we could just go for something like an "Extra Small" VM and paying for the SQL databases by size.

    I have an Azure trial account so I'll be giving this a go but I'm trying to think how it handles hosting multiple websites?

    I'm assuming from what I've read so far that you'd use a CNAME that points to the FQDN of the VM and then use host headers within IIS?

    Basically I'm a little unclear how Azure handles issuing Public IP addresses i.e. does each of my Azure VMs really have its own unique public IP?

  • Hi Paul,

    You can have 1-to-1, external IP to VM if you give each VM its own cloud service. That always happens when you do Quick Create, and if you use From Gallery, that happens when selecting Standalone virtual machine.

    But you can have multiple VMs behind the same external IP address if you do From Gallery and select "join to an existing virtual machine." That gives the VMs internal connectivity to each other, but they are then behind the same external IP so to connect to them you need to connect to unique ports - i.e. the RDP port for VM1 will be different than for VM2.
