I'm in a situation where I've been trying to, almost for practice, scale my app before release. That means learning Kubernetes and CDNs and more. Because it's a side project in my spare time, I was haemorrhaging money to GCP, in part because of the ArangoDB.
I'm still not very confident in my scaling or sharding skills. I've lost data a few times. A $0, $15 or $50 learner plan would really help me stay on board and evangelize it. Take a look at mLab/MongoDB Atlas: https://mlab.com/plans/pricing/ ($0, $15 and $150 plans).
Lastly, getting deployment options on Alibaba, Huwawei and Linode cloud services would be great. Arango has expanded from Europe and if they don't strike the North American popularity they want, they would be fool-hearty to miss Asian markets--and many of their western customers may ben seeking high availability there. Or just brands better trusted than Western countries.
But yeah, hope I can finally get some reliable Kubernetes!
It would be nice if it was easier to see pricing, but the fact I looked for that first probably suggests I'm not the type of person this is aimed at!
Managed services can beat this price by a huge margin, although they seem expensive at first glance.
If you need to scale-out, the ArangoDB packages are more affordable then MongoDB Atlas, as you don't need to spin-up a whole 3 node replica-set to add another shard to your cluster. The smaller instances are cheaper in Atlas, here you benefit from the established cloud service, which can negotiate better conditions with the large cloud providers. However, we will pass on lower cloud costs to customers, so there is hope that we will move closer over time. But, I don't see ArangoDB in direct competition with smaller, pure document-use cases. Most users need the multi-model capabilities and use graphs in combination with document operations.
You can see the exact pricing for the deployment configuration you desire within Oasis when you create a deployment. In general, the actual price for your deployment depends on the cloud provider, amount of main memory & storage you selected. The pricing is usage based, so if you only need a deployment for one hour, you only pay for that hour. Hope this helps a bit at least.
