He has a particular focus on advising technology product managers in product planning and product development. From a technology point-of-view, his main area of focus is the evolution of the data center in the light of the major changes currently in play: the continued growth of cloud service providers and the resultant shift in most organizations to hybrid IT; the evolution of software-defined infrastructure; the influence of web-scale IT on the enterprise; and the increasing presence of hyperconverged systems in the data center.

When working with technology and service providers, Mr. MacLellan's research focuses on how to evolve and position technologies and services to succeed amid the changing buying patterns and expectations of the market. When working with data center managers, he will advise on how best to exploit the current and emerging technology and the differing options in service delivery and consumption, in order to best satisfy the needs of their organizations and workloads.
