Thanks for finding the time to meet with me this evening, Bill – I look forward to repeating this in the future. You’re a true inspiration and someone I’ve looked up to since getting started with SharePoint.
Update: while the VIP address is guaranteed for the lifetime of the deployment – a customer recently lost their VIP address which resulted in their custom domain name become unresolvable. Whilst this was acceptable as we were still in a phase of testing it did cause me some concern. Why had the VIP address changed without our knowledge – we had not made any configuration changes to causes this. I did some further research and found an article (Using custom domain names with Windows Azure Cloud Service) in the Documentation section on the Windows Azure website where it advised you should use CNAME records and point these to your *.cloudapp.net domain name. I asked the customer to do this and we have been able to use the system since.
This post describes how I configured one of my Windows Azure hosted Virtual Machines with my domain name registrars DNS – this meant that I could make SharePoint 2013 available using my domain name.
On the virtual machine instances, page in the Windows Azure Management Portal (https://manage.windowsazure.com) browse to the virtual machine you want to configure with your external DNS.
On the right, in the “Quick Glance” section you will see that a “Public Virtual IP (VIP) Address” is listed (this is shown in the image below but for security purposes, I have changed my VIP to 126.96.36.199). The VIP address is the IP address I need to direct my external DNS to.
“If that is not possible (e.g. you must delete/deploy), then a little planning beforehand can still help here: just create a new hosted service, update CNAME and A record to new hosted service (but keep old deployment there). Wait 24 hours and it should be safe to delete the older deployment.”
I also decided to add a shorter TTL to my A record just in case the VIP address does ever change for whatever reason and I need to propagate a change quickly. I’m not sure if this is advisable or not and am seeking confirmation on this.
A quick test you can do before making any changes to your DNS is to browse directly to your VIP address (http://188.8.131.52). This in my case took me to the default IIS site however this will depend on your configuration.
After I confirmed that the VIP address was accessible I then proceeded to make changes to my external DNS through my domain registrars control panel – in this example, I wanted to point a host record (or an A record) to my virtual machine.
