The concept that is most relevant for the safe execution of applications on virtual machines is sandboxing. Sandboxing is a security mechanism that involves isolating the execution environment for an application, allowing it to run in a separate context away from the host system and other applications. This isolation helps prevent any vulnerabilities or malicious activities within the application from affecting the wider system or other applications running on the virtual machine. By using a sandbox, you can ensure that applications operate within a controlled environment, which is particularly important for testing untrusted code or running applications with varying levels of security requirements. This helps in reducing the risk of system compromise and protects sensitive data. Other concepts, while related to virtualization and cloud computing, do not specifically address the safe execution of applications in the same manner as sandboxing. Snapshots deal with creating point-in-time backups of virtual machines, which can be used for recovery purposes but do not inherently provide a framework for secure application execution. Virtual OS refers to the operating system that runs within a virtual machine and does not inherently address safety measures. Virtual hosts are aimed at managing multiple virtual machine instances on a physical server but do not specifically relate to the concept of securing applications running within those instances.
