Where Forrester's first report on the market for converged infrastructure (CI) solutions focused on the benefits and taxonomy, this second report focuses on the vendor landscape and vendor solutions. As the market for CI solutions matures, IT infrastructure and operations (I&O) professionals can now choose among three distinct types of CI offerings: modular converged infrastructure architectures, integrated application-specific platforms, and software-defined infrastructure solutions. I&O professionals should read this report to understand the vendor landscape of these three types of CI offerings, how these offerings compare and diverge in function, and their applicability for specific workloads.
