Abstract
IBM® CICS® Transaction Server is a transaction server that primarily runs on IBM System z® mainframes under IBM z/OS®. It controls the interactions between applications and users (from a small number of users to thousands of them). CICS applications offer high availability and easy scalability. CICS applications have built-in redundancy, which uses various client interfaces that range from terminals and web browsers to web services.
As this IBM Redbooks® Solution Guide describes, the CICS application architecture has several business and technical benefits.

IBM® CICS® Transaction Server is a transaction server that primarily runs on IBM System z® mainframes under IBM z/OS®. It controls the interactions between applications and users (from a small number of users to thousands of them). CICS applications offer high availability and easy scalability. CICS applications have built-in redundancy, which uses various client interfaces that range from terminals and web browsers to web services.
CICS Transaction Server has a wide range of capabilities that can be used readily by applications that are deployed into its run time. Application architects can rely on the runtime qualities of service that are provided by CICS, without needing to design these qualities of service into the application code. Such qualities of service include security, transactional integrity, and the dispatching of work for multiple processes or hardware clusters.
As this IBM Redbooks® Solution Guide describes, the CICS application architecture (Figure 1) has several business and technical benefits.
