key issus:How should users best select server platforms and vendors for RDBMS and application server roles during the next five years?
the chart above summarizes our major findings regarding three critical differentiators for XXplatformselection:Market share(a current snapshot--except improvements for windows NT and Sun),Performance and scaling(determined by current high water markes)and high availabilit(failover and clustering functionality).By the time a platform decision must be made .most users have already contracted with an externalservice provider or system integrator for the XX implementation assistance required,so system vendors XX professional service expertise may be an irrelevant differentor.The timeliness and quality of system vendors^ hardware and software maintenance can be a differentiator .but only if verified by "local" references .System vendors that propose a heterogenous solution introduce another level of management and problem resolution complexity and management cost into the picture.
acyion item:we recommend that users always check vendors lacal refences for hardware maintenance,due to extremequality variations we have seen on a geographic basis
