What is Cloud computing?- initial guide
Cloud computing is defined as “An internet based computing” in which cloud word is used as a metaphor for the “internet”. It allows the sharing of resources rather than having local resources and personal devices to handle applications.
Cloud computing offers different services such as servers, storage, applications and other hosted services that are delivered over the internet. It allows consumer and businesses to use applications without installation and access their personal files from any computer through the internet.
TYPES OF CLOUD COMPUTING
There are following three types of cloud computing:
Cloud computing is categorized into three types -Public, Private, Hybrid
Private cloud is the cloud computing model which is created for a single organization, whether managed internally or by a third-party. It is able to host either internally or externally. This model offers versatility and convenience while preserving management , control, and security.
It is the cloud computing model where the service provider makes their computing resources available online for the public. It allows the users to access various important resources on the cloud such as – Software, application, and stored data.
Public cloud services are sold on demand, typically by minutes or the hours. The customer only pays for the CPU cycle, storage or bandwidth they consume.
Leading Public cloud providers are Amazon web services(AWB), Microsoft Azure, IBM/Soft layer and Google compute engine.
Hybrid cloud is the combination of private cloud and public cloud in which different entities are bound together.
By using it a company can run mission-critical workloads or sensitive data on the private cloud. While public cloud is used for the bursty workload that must scale on demand. An example of hybrid cloud is one where IT organizations use public cloud computing resources to meet temporary capacity needs that can not be met by the private cloud.
So the goal of Hybrid cloud is to create an automated , unified , scalable environment. It can provide all advantage of public infrastructure while still maintaining control over mission-critical data.
BENEFITS OF CLOUD COMPUTING
Cloud computing has several attractive benefits for businesses and ends users in which some mains are:
By the use of cloud computing, you don’t need to worry about data lost because your data is stored securely in the cloud. So a stray laptop is just an inconvenience, not a potential disaster.

PAY PER USE –
It allows to their users to pay only for the resources and workload they use So there is no wastage of money.
It designed to be accessed securely from anywhere , anytime and from any device.
SELF-SERVICE PROVISIONING –
End users can spin up computing resources for almost any type of workload on demand.
