So be more constructive, I'd like to learn more about IBM Cloud as I have no experience with it. Is there a Lambda-like service, pay-by-use 'serverless' database hosting, and support for direct client-to-DB connections with RLS/ACLs?
Are you looking for something inside IBM cloud? If not, FaunaDB might be interesting? It's a serverless database, pay as you go (with free tier), security layer for client to DB connections, strongly consistent, scalable and distributed (multiple regions). Disclaimer: I work for them.
I looked it up, and I do like it. Thanks for the reference. But, there's one big thing missing and that is the DB needs to be open sourced. Do that and I'll move my projects to your hosted service and promote it everywhere I possibly can.
But, it needs to be open source. Otherwise I'd rather stick with AWS Cognito + Dynamo/AppSync, because primarily that I can depend that it'll be around in five years. Even if I believe FaunaDB cloud will around, I know I won't be able to convince my other stakeholders. But, if it's open source, I can always argue that if FaunaDB-as-a-service disapears, I can host it myself (as a last resort).
