Everyone talks about cloud computing, but not about how does cloud computing work. This is because the end user does not need to know how does cloud computing work in order to use it. You do not need to understand how does cloud computing work behind Facebook, Amazon, Twitter, and Google Docs to use them in your business. For the curious, how does cloud computing work is as simple as you want to make it, and it all extends from what the word cloud refers to.
So, how does cloud computing work? It mostly involves banks of computers working together as a single machine. It is this grid of computers that the term cloud actually refers to. This is not a new concept either. The cloud has been with us since the beginning of computers in various forms. What is different is that this collective virtual computer acts like a single machine.
How does cloud computing work with these clusters of computers? Since we are dealing with a virtual machine, the cloud computer utilizes the resources of the cluster of physical computers underneath it. The virtual computer then uses these resources to run your applications. These applications run independently of the server cluster underneath which is why you can scale the virtual computer with ease. The virtual computer and its applications are basically floating in a cloud of resources free of the physical world.
So, how does cloud computing work these server clusters to create the end user experience? To answer that, we must split the cloud into two layers. The first layer is the front-end, or public/end user layer. The front-end is what you interact with. This is the virtual machine. It thinks it is a normal computer so it acts like one. All cloud applications run on the front-end.
The back-end is where the magic happens. It is the how does cloud computing work. The back-end of cloud computing consists of the physical hardware clusters and the software that runs them. This also includes the networking technologies that connect them. These computers are designed to work together. They share resources. They share processes. They act collectively as a single machine: the virtual cloud computer. They are designed to be hot-swappable which means you can connect or disconnect them without turning them or the cluster off. If you need more resources, you just need to plug in a new … Read More
