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.

In this computing, the word cloud is used as a metaphor for ‘The Internet‘ where different services. such as servers, storage and application are delivered to organisation’s computer and devises through the Internet’

Cloud computing uses networks of large groups of servers typically running low cost consumer PC technology with specialized connections to spreed data processing chores across them. This shared IT infrastructure contains large pools of system’s that are linked together.

Virtualisation techniques are used to maximise the power of cloud computing.

Could computing services can be private, public or Hybrid.

Private Cloud Servers:- These services are delivered form a business data center to internet users. Private cloud Servers offers versatility while preserving management, control and security.

Public Cloud Servers:- In public cloud servers, a third-party provider delivers the cloud service over the internet. public cloud services are sold in demand, typically by the minute or the hour.

Hybrid cloud Servers:- Hybrid cloud servers is combination of public and private cloud servers with automation between the two.The hybrid cloud is to create a unified, automated, salable environment which takes advantage of all that a public cloud infrastructure can provide.

Cloud computing has always been divided into the broad service categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
