ZeroVM

ZeroVM is a lightweight, secure, and resource-efficient execution environment designed for running applications in a cloud environment, emphasizing security and isolation. It leverages virtualization techniques to create a highly isolated sandbox for each application, providing enhanced security and reducing the risk of cross-application interference.

ZeroVM is commonly used in cloud computing, particularly for applications that require high levels of security and isolation, such as data processing, scientific computing, and distributed systems. It aims to minimize the overhead associated with traditional virtualization technologies like virtual machines, offering a more lightweight and efficient alternative.

The key features of ZeroVM include its security model based on the principle of least privilege, resource isolation, and support for a variety of programming languages and execution models. It achieves security through memory isolation, file system restriction, and network access control. This isolation ensures that if one application is compromised, the impact is limited to that specific sandbox, preventing attackers from gaining access to the host system or other applications.

ZeroVM is often compared to containerization technologies, but it distinguishes itself through its emphasis on strong isolation boundaries and its use of virtualization at a lower level. It has been utilized in various research projects and commercial applications focused on enhancing cloud security and efficiency. Its architecture supports resource accounting, allowing for precise monitoring and control of resource consumption by individual applications.
