What is sna server?

SNA (Systems Network Architecture) Server is a type of middleware software developed by IBM. It is designed to facilitate communication between IBM's mainframe computers and other networked devices and applications.

SNA Server provides connectivity and integration capabilities for a wide range of applications, including terminal emulation, print and file sharing, message queuing, database access, and distributed processing. It uses the SNA protocol, which is a set of rules and procedures for transmitting data over a network.

One of the key benefits of SNA Server is its ability to bridge the gap between legacy mainframe systems and modern, distributed environments. It can enable applications running on Windows or Unix platforms to communicate with mainframe applications and data, without requiring extensive modifications or changes to the existing infrastructure.

SNA Server also offers features like security, transaction management, and remote administration, which can help organizations to improve the reliability, performance, and manageability of their networked environments.

Overall, SNA Server is a powerful and versatile middleware solution that can help businesses to modernize and streamline their mainframe-based systems, while maintaining compatibility with existing applications and investments.
