DNS is part of the cloud

With all the automation promised for an ISV in the cloud, there is a need for a service that most of us take for granted. I had blogged about it almost a year ago, but only recently figured out that I was only scrapping the surface of the problem from a cloud perspective.

If seven ISVs use the same cloud, whose DNS service are they going to use? Inside their cloud operation if an IP address is generated for a machine, how does a Java process open a socket on it? You cannot hardcode IP addrs. How can app guy write an application now that could be deployed behind any FQDN at any cloud. Cloud has multiple zones, how will the app developerknow the zone?

All of these issues cannot be solved by using DNSaaS. Some device inside needs to enable this.
