Worked at a large B2B SaaS from near beginning. You want a hybrid; shared DB, but with the ability to move to a 'shard/pod' architecture where you separate out your customers/users into different dbs / apps servers as you scale.
We did it about 3 years in, when DB became a scale challenge. Eventually you'll also get to the point where you want to be able to rebalance and migrate data between each shard.
All of this is nothing you should be trying to solve too early; i struggle to think of any real benefits of single DB per user, unless you are separating out all architecture- including app servers - and that might only be relevant for large enterprise customers? Selling in that market is hard.
Elastic.co the n'th most valuable company on Earth and controlled by Earth's n'th most wealthy human being, cloned an open-source project, Lucene, made it easier to operate, and then sold access to it.
The report is partly based on a questionnaire[3] which asks questions about pluralism, media independence, environment and self-censorship, legislative framework, transparency, and infrastructure. The questionnaire takes account of the legal framework for the media (including penalties for press offences, the existence of a state monopoly for certain kinds of media and how the media are regulated) and the level of independence of the public media.
--Presumably the evaluation 'downvotes' the independence and self-censorship of US media?
I have had to use a online banking site (from a very, very big global corporate bank) which implemented a keyboard in the (Desktop) browser which you had to click each letter with a mouse to type out your password (in the name of security, presumably).
