depends on your cloud provider. I deploy on Joyent, and I can create a cron job if I desire.
I have complete control of my Apache environment. Joyent provides you a Solaris Zone, it's a complete virtual Solaris operating system, I can deploy Apache any way I want, I can restart Apache, *****, I can even reboot the machine if I want!!!!
You can do it if you deploy on a Joyent Smart machine, a 1/4 Smart machine is $25/month.
That's guaranteed 1/4 of a DELL quad dual core machine, if the other three users are not doing anything, I can consume upto 95% of the machine.
