Private, Public, and Hybrid Cloud

What is a Private Cloud 

A private cloud implementation aims to avoid many of the objections regarding cloud computing security. Because a private cloud setup is implemented safely within the corporate firewall, a private cloud provides more control over the company’s data, and it ensures security, albeit with greater potential risk for data loss due to natural disaster.

A private cloud is designed to offer the same features and benefits of public cloud systems, but removes a number of objections to the cloud computing model including control over enterprise and customer data, worries about security, and issues related to regulatory compliance.

What is a Public Cloud?

A Public Cloud is a form of cloud computing in which a company relies on a third-party cloud service provider for services such as servers, data storage and applications.

 

A public cloud can free companies from the potentially expensive costs of having to purchase, manage and maintain on-premises hardware and software infrastructure.

Public clouds can also typically be deployed much faster and with more scalability and accessibility than on-premises infrastructure as a result of the public cloud provider’s existing infrastructure. Public cloud users may subscribe for services on a “pay-as-you-go” fee or fixed monthly fee for the specific cloud services subscribed.

 

What is a Hybrid Cloud?

A combination of public cloud and private cloud (aka Hybrid) where some critical data resides in the enterprise’s private cloud while other data is stored and accessible from a public cloud provider.

With a hybrid cloud, enterprises are able to mix and match cloud resources between local data center infrastructure and scalable, on-demand infrastructure, with the cloud provider typically fully managed.

Hybrid clouds combine the advantages of scalability, reliability, rapid deployment and potential cost savings of public cloud with the security and full control of private cloud.
