Microsoft's method is to use high-performance web server, scalable object requirements management (COM), strong distributed transaction managers, intermediate-oriented intermediate software servers (Microsoft Message Queue) Server) and other application services are directly integrated into the operating system of Windows NT Server. These application services work together through a common architecture in Windows NT, including distributed security (based on Windows NT and Kerberos), scalable network services (X.500 and LDAP), built-in for TCP / IP and Network support from other protocols. All services that run Windows and other operating systems can be obtained by public protocols and published interfaces.
Microsoft's model is integrated with application services in the underlying operating system, which forms a distinct contrast with the "hierarchical intermediate software" that is often seen on the UNIX platform. In this method, the convenience of supporting a variety of different implementation methods requires the application service to be on the upper layer of the operating system and provides a set of separated services for factors such as security. This will lead to greater complexity, higher development and configuration costs, and greater challenges for developers and users in transplantation.
