Isolation is one of the core issues for cloud computing. People had few concerns about isolation until recently when Spectra and Meltdown happened: an attacker was able to cross virtual machines due to an issue in modern computer architecture related to pipeline. Some people think the issue can be fixed using software patches. Others suggest it can only be fixed by a new generation of central processing units (CPUs), because the issue exists on the hardware architecture side.

Conduct research on isolation (of virtual machines) and discuss which of the just-stated positions you support. Justify your position with a well-reasoned argument.
