I totally bought into GAE when it was first released - evangelized it, wrote and adapted a bunch of libraries for it and ended up implementing a dozen or so projects on it. The price hike completely killed me. I optimized what I could but there wasn't much to gain. Because of the way GAE is architected it forces you into efficient design. I switched to AWS, and now with a lot more traffic across all the apps I am still paying ~20% of what my GAE bill was. I invested a lot of time into the platform, only some of which can be applied to other platforms, and fell for the bait and switch. I really don't like what Larry has done with squeezing profit out of each business unit - the pricing just doesn't make sense for eg. implementing a simple spam filter for blog and forum comments using the Prediction API cost $30 per month alone for a site with thousands of visitors. Completely killed a product that could be the center of making Google the best cloud platform for developers.
