So how does cloud server hosting work? Well, this is a question that most of us have asked ourselves at one time or the other. Cloud computing has been in the offing for quite some time. It has been referred to as an ASP (Application Service Provider) and SaaS (Software as a Service). This implies that any software you may need from a cloud can only be provided via its working terminal or the side that you need, and not directly.
Understanding the Cloud
The Cloud generally operates like a rehashed distributed system. Take, for instance, the client-server relationship in a company: the server stores programs and data. The client (or employee) has to access the server to get the data he needs or operate any software. If we take the cloud computing company's server room to be the 'back end,' where all software installations, updates, and data processing takes place; the client's computer would thus become the 'front end,' and it would only run on a 'what-you-need-is-what-you-see' basis. Here, the client doesn't need to worry about server issues. Instead, he only has to ask to work on a specific program on the server to get a particular job done.
Therefore, a cloud is an array of virtual computers that have certain resources on massive server farms that a user can easily access. With a grasp on the structure and operation of an ordinary server-client database, you only need to add the internet to this set-up, and you are done.
To understand cloud computing, we can look at it from the following perspective:
The Back End
The back end comprises the multiple servers (each holding one application or software) that work together. There is also the administrator server that controls and manages all these numerous dedicated servers. You will also get the option of storing data onto the server which will probably be password protected or encrypted, alongside other securities.
The Front End
The front end is the customer's end of the cloud service. As a user, you have to approach the service provider, who will then tell you the procedure involved in subscribing to their packages. So, anytime you need to run a software/application or access a file, the Cloud accepts your request. It then connects to the appropriate server, and in no time, the requested application is sent right to your screen.
How the Cloud is used
One can choose to subscribe to several service providers, such as IBM and Amazon Web Services. Once you subscribe, you have to log in via the internet and then select that particular software you want to access. With this, you don't have to download or install anything as you will be using the Cloud's software and not your computer's! You will also only pay for the service as there is no downloading cost charged on the software. You equally don't have to worry about updates or the OS you are using because the Cloud ensures uniformity and compatibility for all its users by having them use its OS.
The Cloud can additionally be well described as an amalgamation of one-way grid computing and utility computation. To better understand how a cloud server hosting works, you must recall this basic principle – clouds gather, what we use.
