gVisor is an open-source, application sandbox developed by Google. It functions as a thin virtual machine layer that sits underneath a container and isolates applications from the host operating system kernel. This isolation offers several key benefits:

Key Features:

• Enhanced Security: Isolates applications from the host kernel, preventing privilege escalation and malware attacks.

• Resource Control: Limits access to system resources like CPU, memory, and files, improving resource management and security.

• Sandboxed Execution: Ensures applications cannot directly interact with the underlying host system, strengthening security posture.

• Lightweight & Performant: Runs as a user-space process, minimizing overhead and maintaining good performance.

• POSIX and Linux Compatibility: Applications running in gVisor experience a familiar Linux environment, simplifying adoption.

Benefits of Using gVisor:

• Improved Security: Offers an additional layer of security for containerized applications, mitigating vulnerabilities in the host kernel.

• Streamlined Application Deployment: Enables consistent and secure deployments across diverse environments.

• Resource Management: Enforces resource boundaries for applications, leading to better resource utilization and predictability.

• Reduced Attack Surface: Limits the potential attack surface for malicious actors, enhancing overall system security.

• Portability and Compatibility: Ensures applications function as expected across different systems due to POSIX and Linux compatibility.

Common Use Cases:

• Securing containerized workloads: Deploying sensitive applications in gVisor sandboxes for enhanced security.

• Running untrusted code: Executing code from unknown sources with minimized risk using gVisor isolation.

• Developing secure applications: Building security-conscious applications with gVisor as a development and testing environment.

• Improving cloud workload security: Enhancing security in cloud environments by deploying applications with gVisor sandboxes.
