Which technologies allows multiple applications to execute in isolated user spaces, share the same operating system kernel, and run on various types of infrastructure without needing to adjust for each?

OS-level virtualization

Explanation:

OS-level virtualization in cloud infrastructure allows the division and full utilization of resources of one hardware allowing it to run more than one or multiple operating system. With this technology, each operating system is dedicated to one user space instance called a virtual machine, and each user space is independent of other operating systems or user space instances in the kernel such that the failure of one operating system does not affect others.
