In small amounts, cloud storage is fairly inexpensive. You can even get a few gigabytes of free storage with most office plans. But once you start to grow your cloud storage needs into the terabytes, the dollars begin to add up.
For example, I use Apple’s 2TB iCloud plan at $10/month. I also use Google Drive for cloud storage. In order to house my company’s 57TB of data, I had to sign up for Google’s Enterprise plan. For now, that costs $100 per month. Google has said that pricing will go up, but they haven’t published what the increase will be for Enterprise plan customers.
