So basically you are looking for Database service providers. The market is full of them but in my last Semester, I read a course on Cloud Computing where I was taught the use of AWS, and Azure. And both platform has the functionalities you are looking for. And they provide some next level of security. For example, when you will read the whitepaper provided by Azure then you will read somewhere that they did not provide users' data even to governments until you will give them permission.

Ans AWS is also a good option for you. Selection depends on your use and longevity of yours. For the long term, you should prefer AWS Databases services and for the short term, you should use Azure because azure will cost you more when you will use it for a longer period of time. You can still use their calculators to calculate your budget. Note*Forgive my suggestions if they are irrelevant.

If you spec out what you need want first it's going to be an easier discussion with providers.
Things like do you need RAID or backup what OS what support options how much storage and so on?

I can do something as simple as throwing a 6th gen i7 machine in our DC with a 256GB m.2 and install an os and give it an IP for a ton less money then getting you a cpanel control and putting it behind a firewall. Need RAID 1TB? Well that's also going to be more. Want off hours phone support that's going to be more and so on. Want a bunch of software pre installed configured that will cost you more. I can keep going but I think you get the point.

I even have a stack of PI for friends sitting on a shelf if that is all you need.

So before you shop, figure out EXACTLY what you need.

ANY service provider even if I am having my job do it for you as a bitcointalk friend is going to hand your data over to the government if they show up with a subpoena court order.

Its not that i wanted you to use AWS or Azure but after reading your reply i became more interesting in knowing about it. Because one thing i can also say for sure, even if the platforms like Huawei (who got banned to use Google service provided by USA) mentioned in there policy like azure mentioned in there whitepaper that. They will not leak users information but still many platform like aforementioned do that. And make some extra bucks. So, i have no words for Azure.

But i didn't find any statement saying that AWS doesn't support cryptocurrency related work, because they are integrated with 70+ blockchains and who is going to tell them you are using crypto related work. means they will not ask you why you need this service. You only hade to select your required hardware and buy it. Then start uploading and downloading the Data into your DB. Although if you find it expensive and that's why you are giving up on it then it's ok.
