Cloud. No, not the one in the sky. We are talking about the digital cloud. The one that you use for your storage like Google Drive or for your work – Microsoft Office 365. These are cloud services that you use on the internet, but where are they physically located?
What exactly is it? “Cloud computing” is a term that unites different services like storage, computing, platforms for apps and games, servers and more. It provides powerful computers which clients can use (not own) for a subscription fee(monthly or annually). Usually, the service provider offers different plans that can satisfy small and big customers and provide options for upgrades.
So now that we know what the cloud is, where is it located?
The cloud is a combination of different data centers from all around the world that are connected to a grid. Data centers are physical places full of high-end computer servers that require a controlled environment.
The locations are also known as Points of Presence (PoPs). They are strategically located around the world depending on the need for them. This is why you can find a lot more PoPs in Europe, North America, and Asia than in Africa or South America. The proximity of the data center and the consumers guarantees better and faster service.
Apart from the proximity and speed, the grid of the data centers has other advantages. It provides redundancy. If you have data in the cloud, it is not saved only on a single drive. It is divided among or copied to more than one computer depending on the RAID configuration. If one of the drives dies, you won’t lose your data.
Redundancy will be an advantage in any case, for whatever reason you are using a cloud service. If you use the service to compute or to complete a task and one server is down, you will be able to use the resources stored in another drive.
The whole cloud is like a smart organism that provides resources and extra security to clients from all over the world.
There you have it – the cloud is actually a vast network of connected servers that communicate with each other so you can get the best service, no matter where you are in the world.
