Private, Public and Hybrid Cloud
In previous article Introduction to Cloud Computing and Cloud Computing - SaaS, Paas and IaaS Models we explained the basic features and different models of cloud computing.
In this article we will explain the differences between Private, Public and Hybrid cloud.

SAP HANA Cloud Platform PaaS
Private Cloud

Private Clouds consist of cloud infrastructure that is deployed solely for a single organization, whether managed internally or hosted by a third-party externally.
These clouds offer the greatest level of security and control, but they require the company to still purchase and maintain all the software and infrastructure, which reduces the cost savings.
There are two variations of private clouds:

On-Premise Private Cloud: This is also known as an “Internal Cloud,” is hosted within an organization’s own data center. It provides a more standardized process and protection, but is often limited in size and scalability. On-Premise Private Clouds are best used for applications that require complete control and configurability of the infrastructure and security.

Externally Hosted Private Cloud: This private cloud model is hosted by an external cloud computing provider. The service provider facilitates an exclusive cloud environment with full guarantee of privacy. This format is recommended for organizations that prefer not to use a public cloud infrastructure due to the risks associated with the sharing of physical resources.

Best suited for:
Private cloud is best suited for businesses that must comply with strict regulations or that have highly critical applications will choose internal Private Clouds. With a private cloud, businesses install their own server and storage hardware but have the flexibility to shift workloads among servers as usage spikes or they deploy new applications.

Public Clouds

A Public Cloud is one that’s based on the standard cloud computing model where services, applications and storage are made available to users over the Internet - typically on a Pay Per Use model. While Public Clouds are appealing to many businesses as they reduce complexity and lead times, because the underlying architecture is fixed, there is less scope for customization for security and performance.

Public clouds are owned and operated by third party service providers. Customers benefit from economies of scale, because infrastructure costs are spread across all users, thus allowing each individual client to operate on a low-cost, “pay-as-you-go” model. Another advantage of public cloud infrastructures is that they are typically larger in scale than an in-house enterprise cloud, which provides clients with seamless, on-demand scalability.

Best suited for:
Public cloud is best suited for companies that need to bring a service to market quickly, have less regulatory hurdles to overcome, or are looking to outsource part or all of their organizational IT requirements. Under this scenario, the business can simply sign-up for and start using Cloud Computing, online storage and other services immediately.

Note:
The lines between private and public clouds are blurring. For example, some public cloud companies are now offering private versions of their public clouds. Some companies that only offered private cloud technologies are now offering public versions of those same capabilities.

Hybrid Cloud

As the name suggests, a hybrid cloud comprises both private (internal) and public (external) cloud services.
Hybrid Clouds combine the advantages of both the public and private cloud models. In a hybrid cloud, a company can leverage third party cloud providers in either a full or partial manner. This increases the flexibility of computing.
For example, suppose your company offers services that are tailored for different vertical markets. You can use a public cloud to interact with the clients but keep their data secured within a private cloud.

Best suited for:
Hybrid cloud is best suited for E-commerce. Because e-commerce sites must respond to fluctuations in traffic both on a daily and seasonal cycle, the actual work of processing the orders can benefit from the elastic characteristics of public cloud resources. On the other hand, legal regulations strictly govern how personal and payment information can be handled, and this type of sensitive data is more secure if it stays “on-premise” in the Private Cloud. This hybrid solution represents the best of both worlds as it places the order processing and transactional front-end of the shop where it can take advantage of resource scalability, while it keeps the payment and account management services strictly private.
