For example, Adobe recently moved its creative services to the cloud. You can no longer buy the Creative Suite (Photoshop, InDesign, etc.) in a box set. Instead, you must pay a monthly subscription fee to use each individual service. That’s why it’s now called the “Adobe Creative Cloud” instead.
Other servers in the network are responsible for storing data.
For example, when you take a picture on your smartphone, it is stored on your phone’s internal memory drive. However, when you upload the photos to Instagram, you are uploading it to the cloud.
So remember: “The Cloud” is a network of servers. Some servers provide an online service, like Adobe Creative Cloud, and others allow you to store and access data, like Instagram or Dropbox.
Chances are, you encounter the cloud daily. From Google Drive to SkyDrive to iCloud to Evernote, any time you store information without using up your phone’s internal data, you’re storing information on the cloud.
How big is the cloud?
No one knows exactly how much space can be provided by cloud-based services like Google, Amazon or Facebook; however, the cloud can store about 1 Exabyte.
But how big is an Exabyte?
An Exabyte of memory can hold the same amount of data as 4.2 million Macbook Pro hard drives. That’s a lot of storage.
How secure is the cloud?
The cloud is great for storing non-sensitive information, like to-do lists on platforms like Evernote. But unsurprisingly, the idea of storing personal information somewhere “up in the cloud” makes many people wary.
Some companies, like Google, are responding to this worry accordingly. Google recently announced it would automatically encrypt data for paid cloud storage service users.
