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!
