Shifting to a Cloud Infrastructure from a traditional hostin

- Since different cloud providers have different security measures and different plans, questions 1 to 3 can't be answered in general.
- Since you didn't tell about your current Information Structure system, nobody can tell the answer to question 4, except you.
- For question 5: cloud and hosting isn't the same. So you can't easily replace the one with the other. For example, gmail (a cloud based mail service) doesn't do you website.

Turkey flipped the internet off recently. So your content is inherently insecure. A government can switch it off as well as those the run your cloud. If your business relies on a cloud they don't own, then you don't own your business. It's that simple.

The cloud is "out of your hands" excluding any contracts agreements, yada, yada. Sure, you can place practically all of your data to the cloud, now you have a partner if your business whether if you like it or not. That business mode depends on each other for obvious reasons.

I just want to point out that anything outside of your walls is open to anyone else, even if not intentional. That's just the nature of all this, but most internal security of data should be kept "in hand" or control. Day-to-day matters are easily handled otherwise, but again you have only marginal control. You still have to have some sort of "internal stored copy" of generation of the day to day events as insurance if lost you have access or reduce data lost. While the cloud provides similar safekeeping, it too relies on your most current data to remain up-to-date as well. If you have the cloud as the primary "input point", then all safekeeping is entirely at their hands. You, remain as a secondary deposit of data as you relay it to internal storage as back-up.

I don't know what level of interaction you want from the cloud, but any services provided shoyld be fully explained and what they derive that.
