Cloud Computing

Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications, so the phrase cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications —are delivered to an organization's computers and devices through the Internet, and this is comparable to grid computing.

How Cloud Computing Works

Cloud computing uses networks of large groups of servers typically running low-cost consumer PC technology with specialized connections to spread data-processing chores across them. This shared IT infrastructure contains large pools of systems that are linked together. Often, virtualization techniques are used to maximize the power of cloud computing.

Advantages of Cloud Computing

Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility over a network, the cloud also focuses on maximizing the effectiveness of the shared resources, Cloud resources are usually not only shared by multiple users but are also dynamically reallocated as per demand, With cloud computing, multiple users can access a single server to retrieve and update their data without purchasing licenses for different applications.

ð  Improve flexibility

ð  Reduce capital costs

ð  Reduce spending on technology infrastructure

ð  Globalize your workforce on the cheap

ð  Streamline processes.

ð  Improve accessibility

ð  Less personnel training is needed
