無限磁盤空間的網絡託管騙局仍然存在並運行

仍然有許多網站託管提供者提供無限的磁碟空間… 但磁碟空間非常昂貴，並且有一個底層媒體來儲存它. 很容易理解，磁碟空間成本與其數量成正比:

您使用的磁碟空間越多, 您的成本越高.

邏輯 101

It is everyone’s dream to believe that a limited resources can (magically) become unlimited.

A successful CDN company launched such offer last month (no name will be given in this article but it is some kind of CDN with a whale). The offer was too good to be true: unlimited disk space for less than $9 每月! After signing up the fairy tale ended: it was a dedicated server with a 4TB disk. In fairness to this provider: a full refund was given when the cancelation was requested.

Now let’s examine data costs: the amount of data is not the only cost factor.

Another important factor is the ability (or not) to access this data (or move it).

Inventory basics

Data is like a heavy digital stone: the bigger it is, the least you want to move it. Amazon AWS (and other cloud companies) understood this a long time ago and created two types of data: hot data 和 cold data. Hot data is the data you access very frequently: like the data sitting in the disk of your own computer.

Cold data is the data that you really do not need every day.

Data fridge

It is a very well named concept: because there are different degrees of coldness. There is a difference between the data you would access once a year versus the data that you might never access again. The colder your data is, the cheaper it will be!
