You can pair Lambda up with AWS API Gateway and get something pretty close to App Engine. What sets Lambda apart is that it is event activated, similar to stored procedures in a database. But instead of updates or inserts to tables, Lambda can be triggered by events in other AWS services (S3 object created, API gateway method requested, etc).
