From Mainframes to Cloud‑Native OS: How Elastos Envisions the Next Generation of Operating Systems

By dividing computer OS history into fifteen‑year windows, the article shows the progression from early mainframes (OS/360) to minicomputers (Unix), PC‑era Windows, and today’s smartphone OSes built on Linux kernels, noting recurring patterns of hardware abstraction, batch processing, and event‑driven programming.

It argues that future OS design must view the OS as a platform for both host and guest containers, separating kernel (CPU, memory, I/O) from middleware, frameworks, and virtual machines, enabling elastic, on‑demand services across diverse hardware.

The piece examines historical milestones—Xerox PARC’s invention of the mouse, Ethernet, and Smalltalk; the rise of Java and metadata‑driven programming; the shift toward component models (COM, CORBA); and the emergence of cloud‑native concepts like instant apps and universal applications.

Elastos is presented as a concrete example of a next‑generation, open‑source OS built in C++, supporting seamless inter‑language calls (C++, Java, JavaScript) without JNI, employing reflection and metadata to achieve “write once, run everywhere,” and integrating cloud‑fog‑edge computing with strict security isolation.

Security considerations emphasize that the OS should own all network communication, preventing applications from direct TCP/IP access, thereby mitigating DDoS and malware risks, while IoT devices become trusted peripherals managed by the OS.

Business models for such an OS include open‑source community support, non‑profit foundations, consulting services, network optimization, and blockchain‑based virtual economies, arguing that openness is essential for trust and ecosystem growth.
