Integration: from simple data exchange to modern composite architects

At the beginning of the era of computer systems, the methods of data exchange were quite simple. For example, systems exchanged files through FTP or communicated through TCP/IP sockets. This direct approach was quite effective for simple cases, but quickly showed its restrictions when the applications became more and more complicated.

🚀 A real breakthrough in complex communication between computers on the network occurred with the introduction of distant challenges of procedures (RPC) in the 1980s. The RPC allowed the developers to cause procedures on remote systems, as if they were local functions, while abstracting from the complexity of network communication.

• 📌 RPC implements the client server model, where the client prepares and series the call of the procedure with parameters, sends a message to a remote server, the server deique and performs the procedure, and then sends a response back to the client.
• 📌 RPC can work in synchronous (blocking) and asynchronous modes. Modern implementation, such as GRPC, support streaming and bilateral communication.
• 📌 Later, in the late 1990s and early 2000s, web services and architecture were widespread on services (SOA). Simple Object Access Protocol has become a standard for corporate integration, introducing a more structured approach to system communication.

💡 Despite the fact that SOAP has given reliable functions for corporate use, its complexity and long-speaking have led to the development of simpler alternatives, especially RST API, which today dominate web services.
