TOTAL COST OF OWNERSHIP AND APPLICATION AVAILABILITY
Two issues that arise when discussing information systems are the availability of user applications and the total cost per network ownership. These two concepts cannot be separated from each company’s strategy for building their internal software infrastructure, which makes them inseparable in many ways. These major issues are at the root of the development of current information systems:
The total cost of ownership and availability of applications. In the IBM environment, businesses can significantly reduce the cost of ownership by merging multiple SNA and non-SNA networks into a multiprotocol internetwork.
An integrated internetwork must support the availability of universal applications on any medium or platform to ensure its success. It must also offer high availability for critical applications, and predictable response times for end-users.
