History of Internet Inter-ORB Protocol

IIOP was developed in the early 1990s, stemming from the burgeoning need for applications to communicate across diverse networked environments. IIOP facilitated seamless interoperability among software written in various languages and operating on different platforms.

It leveraged the widely-used TCP/IP protocol, ensuring broad compatibility and integration ease. While its adoption was particularly prominent in enterprise sectors, the advent of web services and language-specific frameworks has led to a decline in its use.

Use cases of Internet Inter-ORB Protocol

  • Financial trading systems. In large financial institutions, IIOP is used to connect trading systems written in different programming languages. It allows real-time data exchange and transaction processing.
  • Telecommunications networks. IIOP facilitates communication between different network management systems in telecommunications.
  • Manufacturing process control. In the manufacturing sector, IIOP is employed to integrate process control systems with enterprise resource planning (ERP) software.
