The Infrastructure Optimization Model at Microsoft groups IT processes and technologies across a continuum of organizational maturity (for more information, see microsoft.com/io). The model was developed by industry analysts, the Massachusetts Institute of Technology (MIT) Center for Information Systems Research (CISR), and Microsoft based on its experience with its own enterprise customers. A key goal for Microsoft in creating the Infrastructure Optimization Model was to develop a simple way to use a maturity framework that is flexible and that can easily be used as the benchmark for technical capability and business value.

IO is structured around three information technology models: Core Infrastructure Optimization, Application Platform Optimization, and Business Productivity Infrastructure Optimization. According to the Core Infrastructure Optimization Model, organizations that are implementing presentation virtualization for production workloads with Windows Server 2008 are meeting one of the requirements to move to the Rationalized maturity level. This guide will assist in planning and designing the infrastructure for implementing Terminal Services to serve applications, desktops, or both, to end users.

Infrastructure and Business Architecture

Microsoft produces architectural decision-making guidance for IT infrastructure and business architecture. The architectural principles and decisions presented in the Infrastructure Planning and Design series are relevant to IT infrastructure architecture. The business architecture templates from Microsoft focus on detailed business capabilities, such as price calculation, payment collection process, and order fulfillment. Although the IT infrastructure affects business capabilities, and business architectural requirements contribute to infrastructure decisions, the Infrastructure Planning and Design series does not define or correlate specific individual business architecture templates. Instead, the Infrastructure Planning and Design guides present critical decision points where service management or business process input is required. For additional information about business architecture tools and models, please contact your nearest Microsoft representative.
