Let's go for less sad. I've changed the title a little to better reflect the intent of the post.
With regards to cloud - you're right, Amazon and Rackspace and so on are a single point of failure for a lot of businesses... but they also have a lot of people dedicated specifically to keeping their systems secure. The average startup, on the other hand, doesn't.
I'm curious, what was the reason you chose to highly Chartio out of all the companies in the cloud BI space? We actually feel that we have the best security practices in the space, mostly due to the fact that we're the only ones not doing data warehousing, where you're required to upload a copy of your database to the provider.
Luck of the draw, actually. Someone in an IRC channel I'm in mentioned it [in the context of "someone asked me to set this up, I told them heck no"], I glanced at the page, did a double-take.
It's debatable whether DWH is more or less secure than your approach - and it also depends heavily on how the DWH is done. Having to explicitly move data around also gives an opportunity to scrub it.
For the record, the proactive approach you're taking with your responses here is heartening. The goal of my posts is always, in the end, to push for something better, not just tear down what's there. Glad to see that you've an open mind towards improvements.
Those guys for sure have a lot more manpower than we do (so far!) but I might also point out that security isn't totally about how many people you have working on a problem, but how simple you're able to make it. But - that's not me getting into a security argument...
