Hi all, I have not coded for many years so will need to start with beginners books. I want to build a prototype web app which I ultimately hope to sell to mid-large size enterprises. Initially, I need to keep costs down which is why I want to build a prototype myself. I am thinking about MySQL for the database storage. However, I am a little confused as to whether or not I should be looking at building an app in the cloud; building an app locally and porting to the cloud when finished; or just build and store the app on my own server? I have no clue as to the costs of these options and cost is key until I start selling.
