deployment - What technology should I use/how should I deploy my killer web app? -

i decided time write "killer web app" dream about. :-) i've been programmer long can remember i'm not scared of technology, haven't been active in web world decade. looking help on direction should go.

the app i'm considering: (in order of importance)

1) need charge customers securely using else's service 2) must scale 3) must inexpensive deploy 4) must reasonably responsive (much of client side javascript, there server interaction) 5) need database on end (not huge database, need scale client base)

i'm thinking of using following:

technology: mysql, php, javascript deployment: amazon cloud payment: paypal

is right direction?? (any tutorial links appreciated)

use know best.

don't worry much technology choices. technologies list "safe" choices in sense many successful web apps have been built them, know can done. i'd suggest sticking mainstream technologies reason.

also, don't worry much particular techniques , architectures. if app takes off, you're going end redesigning internal architecture anyway maintain traffic. maintain flexible.
