While System/390^TM is the framework in which ITC operates, enterprise hardware isn't purchased for its own sake -- customer benefits derive from business solutions software which S/390 supports. ITC supports the main S/390 operating systems and the diverse applications which run under them.

VM/ESA^TM, a high-performance, interactive operating system for IBM S/390 servers, supports today's computing environments by providing a natural infrastructure for network computing, easily joining multi-system environments. VM^TM (Virtual Machine) is a long-recognized robust computing platform, spanning the entire IBM S/390 family.

VM/ESA^TM environments typically include multiple systems, interoperating with different server types and exploiting Internet technologies and e-business opportunities.VSE^TM protects and leverages investments in S/390 applications, data, skills, and hardware. VSE Webserving access to mainframe resources helps implement e-business solutions at low cost, low risk, and short time-to-market.

OS/390^TM continues the MVS^TM tradition of providing functionality, performance, and reliability, availability, and serviceability (RAS) needed to support critical business applications such as e-business and Customer Relationship Management (CRM), and to respond to sudden unanticipated user demands for additional system resources.

OS/390, VM/ESA and VSE/ESA support e-business solutions, Web-enabling software, connectivity and enterprise systems management products which turn an S/390 server into an e-business powerhouse. IBM's S/390 mainframe product line provides for the most powerful engines for e-transaction processing. It also helps leverage existing computing assets and employee knowledge and skills for maximum return on investment. Key S/390 benefits include:

• Extended scalability for unpredictable transaction surges
  
• Essential reliability and availability
  
• Strategic support and planning resources for ongoing success
  
• Robust processing power to handle 24x7, global demands
  
• Unmatched security
