Pros
Pro Increases application speed considerably
Google App Engine integrates with Google's CDN out of the box and it distributes your application's assets through that, increasing loading speed considerably.
Pro Easy to use
Google App Engine is very easy to use. All you need to do is install the SDK (which in itself is easy as well, and the documentation is very heplful) and run the command needed depending on the type of project to deploy it.
For example, to deploy a golang application, you run golang deploy
inside the project folder and it will be automatically deployed.
Pro Easy setup
It's literally a matter of minutes to get a Python-backed website up and running.
Pro Easy scaling
You pay for a number of "Workers" for your web app (to handle requests), or CPU seconds for code that you run outside a web app, and you can get more workers or CPU seconds by upgrading your plan any time.
Pro Excellent customer service
Really fast turnaround, friendly.
Pro Free option
You can run a website at USERNAME.pythonanywhere.com for free, and it's good enough for a light-traffic website -- it runs 24/7. You get a free MySQL or SQLite database too.
Pro Flexible payments
You can pay monthly and cancel any time, or pay for a year up front to get a discount.
Pro Not too expensive
A basic site with no custom domain is free. $5 a month will afford the user enough power for a typical 100,000 hit a day website.
Cons
Con Not a core Google product faces uncertin future
Google is notorious with flipping on technology directions, this product is clearly not the focus of Google.
Con Expenses are very hard to control
The monitoring for expenses is limited at best.
Con Problematic support even in the paid grade
Con No SQL database available
Google App Engine uses Google's NoSQL cloud database. There's no option to use a SQL database with your application.
Con Python-only on the server side
Obviously you can put JavaScript in your web pages and so on, but you can't use Rails or Node.
Con No WebSocket support
