do you mean the service operated directly by Veeam? So far, Veeam has planned to be a 100% channel company and to give the needed technology to our service providers, which in turn will build the final service. So, even if you cannot buy "VBO as a service" from Veeam, you can do it from several service providers, or you will in the short future, as I personally know many are planning to offer this service.
