It’s highly‐available NoSQL database (Megastore) with ACID transactions based on entity‐groups[1]. No other cloud provider has anything even remotely comparable. And it’s now available outside of the App Engine framework.
I was hoping they’d make App Engine to actually run on GCE, but this is fine for now.
I’m a little bit worried about this though:
> You should be aware that Cloud Datastore has a serving component that runs on Google App Engine, so there will be instance hour costs.
What I think is going on is they are either worried about about DDoSing their internal APIs or they’re not willing to opensource the part of the client that runs on App Engine instances behind SDK. I think there’s a tech talk coming up on Cloud Datastore that may shed some light.
