Deployment Models of Cloud Computing

.

There are four types of Deployment models of Cloud Computing:

1)Public Cloud: In Public Cloud Deployment Model, the public cloud are mainly for the general public who created and stores their data to the third-party server. Here, the services are provided by the cloud providers. These provider companies keep a record of the resources used and bill according to the pay-as-you-use rule. The main advantage of using the public cloud is:it saves time and money. As a public cloud user, you don't have any responsibility to manage or maintain the cloud hosting data centers.It's totally the responsibility of the cloud service provider. So your maintenance cost and time to set up are saved. There is no capital investment is required. Just use the resources and pay accordingly. The disadvantage of using public cloud is that the public cloud user's data is stored on the third-party data center who also has access to it. Secondly, most of the time public clouds have to face outages and malfunctions. 

2)Private Cloud: In the Private Cloud Deployment Model, instead of the general public' the user is an organization that has the number of consumers who owned, managed, and operated by an organization, a third party. Rest the structure of the private cloud remains the same as that of the public cloud. The advantages of a private cloud are better reliability, better performance, high security, customized network, and storage components but the main disadvantage is its cost intensiveness.

3)Hybrid Cloud: Hybrid cloud is a combination of public cloud and private cloud with the orchestration of the two cloud platforms.

4)Community Cloud:Community cloud is just the private cloud but the difference is that instead of a single organization,multiple organizations are involved to use resources from the cloud provider.
