If you're running a cloud provider, it's a much bigger deal.
On the other hand, if you're a cloud provider that multiplexes tons of virtual cores on your physical hardware, I suspect anyone trying to do the sort of careful timing analysis required for these types of attacks would find themselves drowning in noise, as their processes get migrated arbitrarily between cores of hardware shared with tons of others.
