The description is out of date. I will of course cover lighty but I
will also focus on ngxin and apache2.2 as fornt ends and mongrels as
back ends. Although I will cover fcgi as well just to cover the
bases. I do cover working on your own VPS but I will not be going
into details about configuring Xen itself as it is outside the scope
of the book. But who knows maybe in the future or 2.0 or the book I
will cover setting up your own Xen environment. I will also post some
Xen tutorials on my blog once I get some free time(which could be any
year now ;-).
