DynamoDB and Datastore are mostly equivalent in terms of utility and pricing. GCloud also has Big Table if you're dealing with really large data sets/qps.
Lambda and Cloud Functions are competitors, though there are some things you could do with Lambda + API Gateway that you can't quite do with Cloud Functions just yet (pretty narrow scope, though). I prefer the environment for Cloud Functions, subjectively.
