Overview of CloudReady

What is CloudReady?

CloudReady is an operating system based on Google’s Chromium OS project. It is designed to provide a lightweight, secure, and fast computing experience by transforming existing hardware into Chromebooks. Developed by Neverware and later acquired by Google, CloudReady brings the benefits of Chrome OS to a wider range of devices, including older PCs and Macs. Users can enjoy web-centric workflows, cloud integration, and simplified management without the need for expensive new hardware.

Origins and Development

CloudReady originates from Neverware, a New York-based startup founded in 2011. The company’s mission was to extend the lifespan of aging computers by leveraging the open-source Chromium OS. In 2017, Neverware launched the first public versions of CloudReady, which quickly gained traction in education and business markets due to its low cost and minimal maintenance requirements. In December 2020, Google acquired Neverware, integrating its technology and further aligning CloudReady’s roadmap with Chrome OS.

How CloudReady Works

Installation and Setup

Installing CloudReady is straightforward and can be accomplished in a few steps:

• Download the Installer: Obtain the CloudReady USB Maker for Windows, Mac, or Linux from Neverware’s website.
• Create a Bootable USB: Use the installer to write the CloudReady image to a USB drive (minimum 8GB recommended).
• Boot from USB: Plug the USB drive into the target device, access the BIOS/UEFI boot menu, and select the USB drive.
• Trial Mode and Full Installation: CloudReady runs directly from the USB for testing. For permanent installation, select the option to replace the existing OS and install CloudReady on the hard drive.

After installation, the system boots quickly and launches the Chrome browser as its primary interface, providing access to web applications, Google services, and the Chrome Web Store.

System Architecture

CloudReady’s architecture mirrors that of Chromium OS, which itself is the open-source upstream project for Chrome OS. Key components include:

• Linux Kernel: A customized Linux kernel optimized for lightweight performance and hardware compatibility.
• Chromium Browser: The central user interface, offering web browsing, web apps, and extensions.
• Cloud Services Integration: Seamless connection with Google Drive, Gmail, and other cloud-based services.
• Verified Boot: A security mechanism ensuring that only trusted, unmodified system images are loaded at startup.

Hardware Compatibility

CloudReady supports a broad array of hardware, including machines that are over a decade old. Neverware maintains a Certified Models List to guarantee compatibility with popular devices. Key considerations include:

• Processor Architecture: Intel and AMD x86_64-based CPUs are supported ARM-based devices are not supported.
• Memory Requirements: Minimum of 2GB RAM 4GB or more recommended for smoother multitasking.
• Storage: 16GB SSD or HDD minimum SSDs provide significantly better performance.
• Peripheral Support: Wi-Fi, Bluetooth, USB, and audio devices are generally supported out-of-the-box rare hardware may require additional drivers or not be supported.
