Management Summary This Strategic Analysis Report introduces GartnerGroup's new and enhanced spreadsheet-based Application Server Evaluation Model (ASEM) which helps enterprises make vendor platform decisions based on their specific application environment. This model includes a broader array of criteria than our previous model. This report demonstrates the application server selection guide and highlights the best practices for getting the optimum value from the ASEM. The model helps users determine the enterprise suitability of various vendor platforms. However, the model's usefulness is only as good as the preparation and contextual understanding that users bring to the server selection planning process. The best use of the model requires that planners and decision-makers do preliminary homework of their own. Users must understand and develop individualized server selection priorities.

Or the main intent may be to satisfy adequate systems performance and availability characteristics (i.e., "good enough") for a single or selected set of applications -- perhaps for one or many business units -- with ease of manageability and responsive vendor relationships. In another context, the goal may be to serve diverse application requirements -- perhaps even as a centrally managed consolidation server -- through a widely supported architecture with long-term viability. As new products and technologies are introduced, it is GartnerGroup's intent to update the relative scores of the platforms and on occasion, where warranted, update or modify the selection criteria to improve suitability to shifting technology and marketing trends. The Key Issues addressed in this report include: o How will Unix and midrange platforms be compared and selected through 2005? o How will centralized/high-end server platforms be compared, selected and deployed...
