What’s the Cloud? What’s a Private Cloud?

A cloud is basically the Internet, or a network of servers. Using Cloud computing means storing and accessing data and programs over the Internet instead of your computer’s hard drive. With an online connection, cloud computing can be done anywhere, anytime.
The notion of network-based computing dates to the 1960s, but many believe the first use of “cloud computing” in its modern context was when Google CEO Eric Schmidt introduced the term to an industry conference in 2006. “What’s interesting [now] is that there is an emergent new model,” Schmidt said:

“I don’t think people have really understood how big this opportunity really is. It starts with the premise that the data services and architecture should be on servers. We call it cloud computing — they should be in a “cloud” somewhere.”

Cloud computing has been introduced to the masses when the internet started to offer significant bandwidth. The term began to be more and more used the following year, with companies like Amazon, Microsoft, and IBM.

How does it work?

Where is your data stored if not in your computer or somewhere at home?
Well, here 👇
Each file stored in the Cloud is stored in a server, somewhere in the world, depending on which companies you’re using. It’s pretty hard to know the precise location of your data, as companies use multiple servers locations around the world.
So to sum up: your files are stored on a server. There are people who maintain the servers in good care. An Internet connection makes your files accessible to you by accessing those servers.

The Cloud, what for?

Basic daily things like checking up your email (with Gmail for example) or your Facebook account. The Cloud enables you to either run applications called web apps (= an app that doesn’t need to be downloaded on your computer to be used) or, what interests us today store data.

The advantages of Cloud storage

The advantages of Cloud storage are numerous:, it gives you flexibility as your data is accessible from any devices (as long as you have an Internet connection), and it gives you a backup if your computer or phone crashed, as your data is stored on one, or more, external servers.

But is it secure?

Some of the biggest concerns of Cloud storage are privacy and security.
[answer = Tim Cook, Apple’s CEO!]
After all, you are storing very personal information on someone else’s computer. Or at least, on an unknown server somewhere in the world.
This implies that you’re giving up control. This includes the possibility of having your data hacked or stolen (photos, personal documents, etc.), mined for advertising purposes (remember those ads you received constantly in your mailbox?) or requested for by the government.
So while Cloud services often tend to get you free storage for the first gigabytes, there’s the hidden cost of losing control over your files.

So what’s a Private Cloud?

Public Cloud typically delivers a pay-as-you-go model for storing your data on unknown servers. As an opposite, Private Cloud implies a hardware, storage or network that is dedicated to one person, client, or company only.
No data center to store data: this ensures a high level of ownership. You keep total control over your privacy.
Private Clouds can be customizable: you can enforce hardware performance, network performance and storage performance.
