It's a hybrid web and cloud-based operating system built with PHP, JavaScript, and HTML5. Notably, it uses CHAOS Microkernel to achieve massive scalability and supports up to 100 million concurrent users per VM. Its browser-based deployment and cloud-first approach eliminate hardware dependencies, while VeNUS, its enterprise-grade version, offers enhanced security, scalability, and integration capabilities for business needs. ## Content 🚀 GreyOS: The Meta-OS Redefining Cloud Computing GreyOS, conceived and developed by George Delaportas 14 years ago - now supported by PROBOTEK - is the world's first Meta-OS — a hybrid web and cloud-based operating system that transcends traditional hardware constraints. Built entirely with PHP, JavaScript, and HTML5, GreyOS operates through browser VMs and cloud infrastructure, offering a seamless, hardware-agnostic computing experience. 🧠 Architectural Highlights CHAOS Microkernel: A lightweight, cloud-native kernel designed for massive scalability, capable of handling up to 100 million concurrent users per VM. Carrier-OS Bootstrapping: Utilizes a minimal Linux-based OS to initiate the system, which then loads GreyOS via a browser interface, allowing for universal deployment across devices. micro-MVC Framework: A custom MVC architecture optimized for rapid development and minimal resource consumption, ensuring efficient performance even on legacy hardware. Coyote Browser: An integrated browser that serves as the primary interface, supporting dynamic web applications and services within the GreyOS environment. Cloud-First Design: All processing and storage are managed in the cloud, eliminating the need for local hardware dependencies and enabling true device independence. 🖥️ User Interface & Experience Dynamic Window Management: Offers a fully customizable GUI with floating windows, allowing users to tailor their workspace to specific needs. Resource Efficiency: Operates effectively on devices with as little as 512MB RAM, making it accessible for a wide range of hardware configurations. Persistent Sessions: Ensures continuous operation without the need for reboots or logouts, providing a stable and uninterrupted user experience. Meta-USB Deployment: Supports bootable USB installations, enabling users to carry their personalized OS environment across different machines. 🏢 VeNUS: Enterprise-Grade Cloud Computing Platform VeNUS is the enterprise adaptation of GreyOS, offering a closed-source, robust platform tailored for organizational needs. It serves as the backbone for PROBOTEK's diverse operations, including AI, IoT, and drone technologies. 🔐 Enterprise Features Enhanced Security: Incorporates advanced security protocols and has undergone rigorous audits to ensure data integrity and protection.
