Cloud Computing Operating Systems

Cloud is not just a natural form of smoke. It is also the most hyped term in the IT industry right now. Everyone is talking about cloud and vendors all cloudify their products and service offerings. In the area of operating systems this is also happening and a cloud OS is simply a simplified operating system that runs just a web browser (at least that is one definition of it), providing access to a variety of web-based applications that allow the user to perform many simple tasks without booting a full-scale operating system. Because of its simplicity a cloud OS can boot in just a few seconds. The operating system is designed for Netbooks, Mobile Internet Devices, and PCs that are mainly used to browse the Internet. From a cloud OS the user can quickly boot into the main OS, because it is possible to continue booting the main OS in the background while using a cloud OS (at least this is the goal).

Combining a browser with a basic operating system also allows the use of cloud computing, in which applications and data “live and run” on the Internet instead of on the hard drive. This is also referred to as platform as a service (PaaS) and Software as a service (SaaS). A cloud OS can be installed and used together with other operating systems, or can act as a standalone operating system. When used as a standalone operating system, hardware requirements can be very low.

This amazing technology allows a user to access their own virtual desktop from anywhere around the world, without even using having network access to a remote PC. In addition, you are essentially using the Internet to work as a desktop. Wikipedia specifically states that: “Cloud Computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.

Cloud Computing Benefits

Enterprises would need to align their applications, so as to exploit the architecture models
that Cloud Computing offers. Some of the typical benefits are listed below:
1. Reduced Cost
There are a number of reasons to attribute Cloud technology with lower costs. The
billing model is pay as per usage; the infrastructure is not purchased thus lowering
maintenance. Initial expense and recurring expenses are much lower than traditional
computing.
2. Increased Storage
With the massive Infrastructure that is offered by Cloud providers today, storage &
maintenance of large volumes of data is a reality. Sudden workload spikes are also
managed effectively & efficiently, since the cloud can scale dynamically.
3. Flexibility
This is an extremely important characteristic. With enterprises having to adapt, even
more rapidly, to changing business conditions, speed to deliver is critical. Cloud
computing stresses on getting applications to market very quickly, by using the most
appropriate building blocks necessary for deployment.

What is cloud computing?

Cloud computing is a comprehensive solution that delivers IT as a service. It is an Internet-based computing solution where shared resources are provided like electricity distributed on the electrical grid. Computers in the cloud are configured to work together and the various applications use the collective computing power as if they are running on a single system.

The flexibility of cloud computing is a function of the allocation of resources on demand. This facilitates the use of the system’s cumulative resources, negating the need to assign specific hardware to a task. Before cloud computing, websites and server-based applications were executed on a specific system. With the advent of cloud computing, resources are used as an aggregated virtual computer. This amalgamated configuration provides an environment where applications execute independently without regard for any particular configuration.
