I am just getting into some CPA campaigns with an affiliate network for the first time and I need to host the landing page and database. I have been calling around to different hosting companies and haven't found any that were very happy with hosting for a company doing this type of marketing. Does anyone have any suggestions? What should I do for a configuration? I am expecting about 100k hits a day so I was going to load balance 2 web servers connected to a single database server in the back to collect all the data. I know this is expensive I just don't want to have the site go down for any reason during a campaign. Also I was talking to my publisher and he was telling me I need to use a pixel to track opens and various other statistics which I have no idea how to do that can someone explain what I need to do for that?
