What exactly were you looking for? APIs?

Here is a hint: quite many companies need a certificated provider who not only is certified but also has - 99,999% overlook this fact because of ignorance - enough insurance and can theoretically be held responsible financially for services being not reachable.

EU regulation requires such settings.

While I highly value Hetzner and Strato, they don't want to deal with such companies, which is reasonable.

Also what you see is just the visible part, not the internal APIs or due to failure safety different APIs serving in a failover scenario.

Internal networks are huge. And masked or hidden behind quite some intrusion detection as well as layers of protection exactly for this reason.

In other words: you did an interesting posting however it is meaningless without knowing why these what you called churn occurs.

Usually you don't simply migrate from one cloud to another.

Accenture for example had a partnership with Amazon, and use their services. So maybe during the development phase or whatever there appears to be a spike.

In other words: it was a planend. Times series need to be observed for many years.

But nevertheless a nice posting.

It is just that sometimes "facts" from the outside lead to speculations, an insider can only chuckle about.

Before I joined a huge global bank, I thought any startup would eat them alive, think N24. Remember N24? No? Well...

I was part of the senior management, dbCORE as a hint.

Maybe repeat the study, make it run over years, or even better: observe something you know for a fact and see how things change, not the other way around. You would have needed to conduct interviews etc.

By design there is a paradigm called security through obscurity. That's why torture for example seldomly helpful. Is the poor soul lying or not? You need to verify first, in any case.

Outside observation is just that: Platon's allegory of the cave. Useful or not, you never know. That's why I laughed a bit about your disclaimer ("Limitations").
