How Cloud Computing Works?

If you have read my blog on “Living on Clouds, an Office Away From Office!”, you may have understood how cloud helps you deal with the storage problems. Cloud computing also helps you work by sitting in any part of the world.
 
Do you realize that most of the applications we use today, such as Facebook, Twitter, Instagram, Kindle, Netflix, and YouTube, are all connected to cloud? But how do they all work? In which part of the world are they located? Who looks after these applications? How do they provide us 24/7 service, non-stop? In this article, I will help you find answers to all these questions and more. As per Netskope cloud report 2016, following are the most used cloud enterprise applications.



Business needs of every organization are ever changing. To meet these changes, organizations need to invest time and money to scale up their IT infrastructure, such as hardware, software and services. But to scale up all the physical infrastructure in an organization can be time consuming and hard to keep up with the changing trends. Often, an organization is also unable to achieve optimized utilization of the IT infrastructure.
 
See the following video if you are finding it hard to visualize my point:

 
Cloud computing is a paradigm shift that provides cloud computing over the internet. Instead of all hardwares and softwares sitting in the premise of your organization or on organization’s network, it is provided by another organization (a cloud service provider), which has highly optimized datacenters having the required hardwares, softwares and information resources. Here, datacenter means a cluster of computer servers connected over a network and used by an organization remotely for data distribution, storage, and data processing on a large scale. 
Datacenter
Your organization can connect to such datacenters, when required, through internet on pay-per-use basis, or sometimes for free but charged in some other way. The datacenter services provided are maintained 24/7 and 365 days a year by some other organization, and your organization need not know their physical location. For you, they are located somewhere in the fuzzy cloud. For instance, when you post a picture on Facebook, you are actually uploading it to the Facebook datacenter located in some part of the world and your friends are able to view it by connecting to Facebook over the cloud.

Cloud computing helps your organization to avoid capital expenditures on maintaining or upgrading on-premises IT infrastructure. Organization can also avoid scaling-up or scaling-down the infrastructure based on the changing business needs. It also need not worry about virus or security threats since it is being taken care by the cloud service provider.

I hope I was able to answer some of the questions you had on mind about working of cloud computing, in simple non-technical terms. These cloud computing services are deployed through different models, which I have explained in my blog on "Cloud Computing Deployment Models".

Share your cloud computing experience. Do you like it or hate it? If you can do something to improve your experience, what would that be? Leave your comments.
