How much is the "law of spring" really?

I am very carefully filtering the news noise in fb, but even there a noticeable wave of topics with the law of Spring. I will leave the law aside, politics is politics, there’s a triple bottom, but for the sums of money I’ll say, I was after all the deputy head who would have to solve such a problem with his head.

Is a trillion worth of data storage really?

Let's count.

I did the calculation quickly in one comment on fb a couple of weeks ago, it does not take into account the cost of placing equipment in the data center, this and other unforeseenness can be thrown another 10-15% above, but not more.

Spoiler:

no trillions on such a task is necessary, about 200 billion rubles is enough

It is given : it is required to store calls, sms, chats and logs of the Internet and mail. Half a year.

It is necessary : calculate which pieces of iron are needed for this and how much they can cost.

Solution :

Determine the specific volume of voice storage . Hour voice clings to about 10 MB; 24 hours = 240; 365 * 0.24 GB = 87.6 GB per user. Let him say 25% per year (that's a lot), then 21.9 GB per year. Store for half a year means 11 GB per person.

Expertly determine the weight of text entries . All Internet logs and sms / messengers - a text that weighs hundreds of kilobytes and cannot be made in megabytes per day, it is impossible to physically type without having thousands of monkeys with typewriters.

To be sure, add half a year of postal correspondence. Of course, we will include deduplication for 140 million people (we will leave only one attachment, and remove copies of it in other boxes and substitute a reference to the original). And here (by experience) will be added - well, another 100 MB of content per year, there will actually be 10-20. Well, people do not write a lot in the mail, it's all usually a long chat in the form of a beard RE: RE: RE: RE ...

Ok, 20 MB for mail, another 20 MB for chat and browser logs. Total 40 MB.

Together with the voice - the same 11 GB (10240 MB, there are +40 MB messengers invisible).

Next, infrastructure . Conventionally, six months to store all the information on one citizen for a local Palantir will cost (drum roll) $ 3, including:

• $ 0.9 / GB - the cost of storing data on disks;
• $ 2 - infrastructure (hardware, software, implementation) and support.
• these $ 2 are calculated as "we have implemented and amortizing for five years"

How many are there active base for opsos? 120 million? Probably half alive.
Well, even if the Internet users really more, ok.
90 million people. 990 000 000 GB of storage for $ 3.

TOTAL :
In $ 2970 million or 185 billion rubles will cost the creation of infrastructure. These costs should be divided into all telecom operators to record the activities of residents of the whole country.

And this infrastructure, plus or minus, is 70% built now - all telecom operators have data centers, mega-data centers, backup data centers. They even rent them out, because those are underutilized by voice traffic and logs.

So they lie about trillions.

Do not believe.
