I read somewhere that for small applications, Google App Engine is free. Now when I read their docs, it seems that even for small applications, it isn't free.
I just wanted to check here - is it free if the application is under some size?
"App Engine costs nothing to get started. All applications can use up to 500 MB of storage and enough CPU and bandwidth to support an efficient app serving around 5 million page views a month, absolutely free. When you enable billing for your application, your free limits are raised, and you only pay for resources you use above the free levels."
