If you have a data center, you can do two things that are related to the cloud. First, you can connect your existing infrastructure in the data center to public cloud storage services. For example, backup your SQL Server to Amazon S3 or Rackspace Cloud Files. If you happen to be in the same data center with a public cloud storage service provider, such as INTERNAP, you can connect to that provider too and enjoy the fast pipe within the same data center. Second, you can construct your own cloud storage service as a private cloud. For example, you can build your own cloud storage service using Mezeo software and provide the service to your own enterprise that is outside the data center.
