Yes, and that may, depending on the precise requirements of this
particular use case, argue for containers.  Without seeing the whole
picture, though, it's difficult to say which would be a better fit.

There is also some concern about security.  I've kept this handy
for a decade, as a pointed reminder to myself:

	without security holes."

        lot of security benefits",, October 23, 2007

Thus my approach, which is to presume that virtualization of all types
can be an effective tool for resource management and similar tasks, but
it can't be counted on as a security enforcement mechanism.
