An operating system can support multiple accounts. Each account has its own working environment. How does this differ from multiple containers?

An account shares access to the same file system, but can be restricted as to which files and directory it can see and execute.

An account in a chroot jail gets its own view of the entire file system that is completely isolated. The root folder for the specific account is not the root folder for the system as a whole. But the account still shares RAM and the CPUs.

An account running in a container gets a chroot jail plus its access to system resources, such as RAM and the CPU's are restricted. So you could restrict an account to using a maximum amount of RAM and a maximum number of CPU cores.

Applications would be isolated between different accounts. What is the difference between this kind of isolation and the isolation supported by container technology?
