There’s a growing realization that the multitenant approach to the cloud isn’t the only option that companies should weigh in deciding between deploying software on-premises and in the cloud. That some people describe the multitenancy approach as “the real cloud” reflects the contentious nature of some technical debates, especially those that occur early in the evolution of a new technology. Multitenancy does have advantages that confer cost savings, and these have been important in the first stages of cloud adoption. However, we predict that single-tenant structures will rapidly gain in importance as corporations mature in their use of cloud computing, especially with respect to how they manage their ERP systems, as I have written. Corporations are increasingly adopting Web-based applications and moving their computing environments to a hybrid model that combines a combination of on-premises and cloud deployment options (private, community and public; single- and multitenant; or managed cloud). The right choice depends on the needs of the company and the ability of vendors to provide services that match their requirements.
