What is “the cloud” and where is it?
Well, in short, the “cloud” offers convenience of being able to access files from anywhere. It’s just a metaphor for the Internet.
But it is hardly a cloud floating above our heads. In reality, it’s a physical infrastructure, its many computers housed in massive warehouses all over the world. Quite often, people refer to these warehouses as “server farms”.
As long as it’s easy to read email on our phones and watch movies on our laptops, we generally don’t take the time to wonder where our data actually goes, how it gets there, and what happens to it on its way. What happens when you posts photos, files and videos? Let’s take a look under the hood.
Cloud computing basically refers to a process of sharing resources to optimize performance i.e. using a network of computers to store and process information, rather than a single machine. In other words, the cloud is a network of servers, and each server has a different function.This concept has been around for decades, but only now has gained momentum.
A wonderful thing happened about a decade ago – high speed internet connections.Not long thereafter, mobile devices started getting the same thing. So, if devices are always online, and data transfer speeds are good, why not just store all the software and storage online?
Distributing the load across lots of powerful servers means web-based applications can run more dependably and efficiently. These servers are constantly updating, and those web apps more or less always work. If one server crashes, there are others to pick up the slack. Your IT department at work probably loves this idea.No wonder cloud computing is wildly popular at the enterprise level, where IT managers are focused on maintaining stable systems that are used by employees.
What are the benefits to working in the cloud?
The business decision to “move to the cloud” is often financially motivated. Companies used to have to buy their own hardware equipment, the value of which depreciated over time. But now with the cloud, companies only have to pay for what they use. This model makes it easy to quickly scale use up or down.
