Everyone is moving towards cloud!! It has become the new buzz in the market and has continuously been in discussion how it is However the discussion involving the cloud is also indispensable and should need to carefully look at cloud computing, what it has to offer and why so many people are talking about it.
Why Cloud Computing?
The cloud is the internet. But now this time it is different and that the internet is a lot further along now. The old internet was mostly used for sending emails, chatting and visiting the web pages. The current Internet has all the capabilities to run applications. Any user can use the thin client and run a program on someone else’s servers. Imagine that your neighbors have a top of the line computer that can run the biggest applications and software and you have a laptop that can only install the trial version without getting bogged down. Cloud computing allows you to use your laptop to access the processing power of your neighbor’s computer over the internet. This means you can also use every program on it without having to replace your hardware.
The brief explains the basic principle behind cloud computing, except that rather than accessing your neighbor’s resources you tap into a cluster of top-end hardware and only pay for what you are using.
Perhaps most of the people often get confused about cloud computing. If you have a web-based email service like Gmail or Yahoo, then you are already using cloud computing. If you have uploaded photos, or have used google drive, what movie on Netflix then you are already using the cloud services. These all activities are a fit for cloud computing because they don’t need to exhaust your local resources.
The cloud is divided into categories according to the type of services it is providing. These are as follows:
Software as a Service (SaaS): It includes many of the online applications available worldwide. Google Docs for examples works like a traditional word processing document except it is not running on your local machine. It is any program where the majority of the work is being done on another machine rather than over the internet. One of the primary benefits of the SaaS is that it allows you to run the newest software without running on your own machine.
Platform as a Service (PaaS): Platform as a service is like creating your platform expect virtual computer is replacing the old one. With PaaS, you can select the software and services you want and customize them. The PaaS may come with a complete interface like an OS.
Infrastructure as a Service(IaaS): It is one of the first application to which cloud computing is applied. Infrastructure include data storage, web hosting, processing power and so on. Rather than possessing the whole infrastructure like buying the servers, setting them up, managing them, you pay only for the infrastructure like you would a utility. The more you use, the more you pay. This allows your resources to scale up and down as per your needs rather than investing on the resources permanently.
Most of the people may assume IaaS is more of a business aspect of cloud computing. All in all cloud computing is a revolutionary idea. The only thing that is understated about cloud computing is its power. Most of the major market players are working towards in envisioning a future where your device cost is substantially low, and all your data program and work is stored and secured in the cloud.
