What is Cloud Computing

Cloud computing occurs when a network of such servers becomes the tool for storing, managing, and processing data that would otherwise be placed at a local server. Today, various companies provide cloud-computing services to individuals and businesses. Here is a discussion of what is cloud computing.

Main features:

It is easy to scale not only the service hosted in the cloud by also the cloud infrastructure itself. You do not have to switch off the system but only shift loads to other servers then carry on with the hardware upgrade. When you are done, you can then let the system redistribute its load optimally.


The clients do not have to use all the available resources all at once. They can choose only what fits their business interests such as the number of users and the resource required for each of them. The company running the cloud infrastructure still enjoys economies of scale because it is servicing a myriad of clients. In addition, scaling up the resources allocated to a particular client as their demand rises is easy because everything happens on virtually configured systems. Clients share the total severs capacity. At any particular time, the cloud infrastructure will only allocate their systems resources as per their current demand.

Benefits of cloud computing:

The cloud computing arrangements eliminates the need to get new hardware and software whenever you need to extend the existing network of users within an organization. All computers within a system connect to a master server that allows every user to access the same application features. The physical computers become mere terminals for accessing the web-based services. In this case, productivity no longer depends on the capabilities of the local computer or connecting device, but on the capacity of the server that makes up the cloud.

In most cloud computing arrangements, a different company runs the cloud infrastructure and releases the client from any maintenance and administration tasks. The specialization among firms eventual leads to innovation and better concentration on core competencies.

The arrangement is beneficial for tasks that require heavy computing power and minimal user interaction. Things like web-based emails are forms of cloud computing where users only have to issue simple commands to the system and it will go through complex processes of serving millions of commands accurately.

Having applications run on a cloud provides a business with a cushion against natural disasters. If anything happens to servers on a cloud, the current processing load will shift to other available servers and it will be distributed evenly. For the client business, having data storage and processing take place remotely ensures that even in the unfortunate event of a disaster such as a power surge or earthquake, its data will not disappear when the business premises breaks down. The owners and staffs can continue with some of their job functions from remote locations.

The current trends has been for all business computer applications to go the cloud way. They include sales processing systems, human resource management systems and systems for customer relationship management.

The above discussions answers the question of what is cloud computing and moves on to explain its benefits. The concept is no longer novel and has become a natural choice for business looking to operate independent of any location.
