6. •javascript as the

10. “There’s definitely
that concern, We did
an analysis of a

11. “We’ll
continue to
use it and see
how it does.
That’s how
we’ll make
our
technology
choices”

12. They went from running 15 servers with
15 instances (virtual servers) on each
physical machine, to just four instances
that can handle double the traffic

13. I promise
I’ll be good :-)
