IBM CICS® Transaction Server, often called CICS, is a world-class, secure, powerful, scalable, mixed-language application server platform used for hosting your transactional enterprise applications in a hybrid architecture.
An application server provides an environment to host applications. It can provide services to solve concerns like security, transactionality or data exchange between new and existing applications. CICS can provide these services to applications composed of components written in different programming languages.
Applications can be modernized using languages that best fit your developers' skills and your business's needs.
