RPC: The foundation of modern distributed architecture

What Does RPC Really Do and Why Is It Important?

RPC (Remote Procedure Call) is a technology that allows programs to communicate with each other over a network as if they were on the same machine. Instead of developers manually dealing with network protocols, RPC simplifies everything: request and response, without unnecessary details. This simplicity has made RPC an integral part of modern computing systems, from cloud services to decentralized applications.

Where RPC Actually Works

Practical examples show how deeply RPC is embedded in technological infrastructure:

• In the financial world: payment processing systems rely on RPC to synchronize operations across various network servers. Transactions require instant communication, and RPC provides that.
• In telecommunications: operators need the ability to control and monitor network elements remotely – that’s what RPC does.
• In healthcare: telemedicine platforms use RPC to transmit patient data and conduct remote consultations.

Evolution of the Technology: From the 1980s to Today

The history of RPC begins in 1981 when Bruce J. Nelson formalized this concept. At that time, it was a revolutionary solution to simplify network programming. Over the decades, the technology has evolved:

• 1980s–2000s: DCOM from Microsoft and Sun RPC were the main implementations
• 2015: Google introduced gRPC, built on HTTP/2, supporting streaming and language independence
• Today: JSON-RPC has become critical for blockchain ecosystems, enabling communication between nodes in decentralized networks

Impact on the Modern Technological Landscape

The adoption of RPC frameworks has radically changed how scalable systems are built. With the rise of cloud computing and microservices architecture, RPC has allowed companies like Google and Microsoft to create global systems capable of handling millions of operations simultaneously.

Investments in RPC technologies and related protocols have grown exponentially. It’s especially interesting to see how JSON-RPC has transformed blockchain development, enabling nodes to communicate efficiently and supporting decentralized applications (DApps).

Current Innovations and Future Prospects

Today, RPC continues to evolve. Google’s gRPC remains the most advanced implementation for modern applications due to its efficiency and flexibility. In blockchain, JSON-RPC has become the standard for interaction and data exchange between network nodes.

The future of RPC is linked to the development of asynchronous communication and improved security protocols, which are critical for decentralized systems and IoT applications.

Conclusion: Why RPC Remains Relevant

RPC is not just an old technology. It is the foundation upon which all modern distributed architecture is built. From financial systems to blockchain, from cloud services to microservices – RPC ensures seamless communication that keeps the Internet running smoothly. Understanding RPC principles is essential for every developer working on scalable systems in the modern era.
