NOTICE: This post is not very useful as a guide. It is documenting the failures I encountered trying to set up a flat file blog in a subfolder in GAE. Read for your pleasure, but don't try to follow it. Google App Engine (GAE) allows you to set up a simple PHP website easily and for free with generous quotas - more than enough for a low traffic site. There are several guides on how to get one working . However, GAE works differently from traditional web hosting. Access is tightly controlled through app.yaml file; the static files and application files are separate from each other; and the application file system is not writable. As WordPress requires a MySQL database (chargeable under Google Cloud SQL), I looked for a flat file blogging alternative . Dropplets looks too simple and feature-poor. It doesn't have a comment system integration out-of-the-box, but Disqus can be added later. There is no rich text editor - plain text editing required in Markdown syntax....
