  • CICS (Customer Information Control System) is IBM's scalable and secure platform for transactional enterprise applications.
  • Originally launched in 1969, CICS is widely used by governments, banks, insurers, and retailers for high-volume transaction processing.
  • CICS provides common services like security, recovery, and data conversion, reducing the need for individual applications to handle these complexities.
  • It supports multiple programming languages and data types, enabling integration with new technologies like Open Telemetry and AI.
  • CICS simplifies application development by handling security checks and interactions between different programming languages (e.g., COBOL and Java).
  • Despite its flexibility, CICS has complex configuration options, though IBM is working to simplify them using YAML and AI.
  • Almost all consumers interact with CICS indirectly through banking, shopping, or travel booking systems.
  • Learning CICS typically involves on-the-job training, IBM documentation, or courses from organizations like SHARE.
  • Career opportunities involving CICS can be explored through conferences (SHARE, GSE, WaveZ) and online communities like Stack Overflow.
