Kinds of Cloud Computing: Private, Public and Hybrid Clouds

Public and Private Cloud

By cloud computing technology, big pools of assets can be associated through private or public networks. This technology simplifies infrastructure arrangement and offers dynamically scalable infrastructure for cloud based applications, data and file storage. Businesses can choose to deploy applications on Public, Private, and Hybrid.

What are the differences between these types of cloud computing, and how can you define the right cloud route for your organization? Here are some essentials of each to help with the decision-making process.

Public Cloud

Public clouds are ready available to the universal public by a service provider who hosts the cloud infrastructure. Usually, public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. With this model, customers have no control over where the infrastructure is situated. It is important to note that all customers on public clouds share the same infrastructure pool with limited configuration, security protections and availability variances.

Public Cloud consumers benefit from economies of scale, because infrastructure costs are spread across all users, allowing each individual client to operate on a low-cost, ‘pay-as-you-go’ model. Additional benefit 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. These clouds offer the highest level of efficiency in shared resources; however, they are also more vulnerable than private clouds.

The main benefits of using a public cloud service are:

• Easy and inexpensive set-up because hardware, application and bandwidth costs are protected by the provider.
• Scalability to meet needs.
• No wasted resources because you pay for what you use.

Warning : In IT sector executives are worried about public cloud security and dependability. Take extra time to confirm that you have security and authority issues well planned, or the short-term cost savings could turn into a long-term incubus (khwab).

Private Cloud

Private cloud is cloud infrastructure dedicated to a particular body. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often absent in a public cloud environment.  It is not shared with other organizations, whether managed internally or by a third-party, and it can be hosted internally or externally.

A private cloud is the obvious choice when

• Your business is your data and your applications. Therefore, control and security are supreme.
• Your business is part of an industry that must conform to strict security and data secrecy issues.
• Your firm is large sufficient to run a next generation cloud data center efficiently and effectively on its own.

Hybrid Cloud

Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain sole objects but are bound together offering the benefits of several deployment models. In a hybrid cloud, you can influence third party cloud providers in either a full or partial manner; increasing the flexibility of computing.

Here are some terms of situations where a hybrid environment is best:

• Your corporation wants to use a SaaS application but is concerned about safety.
• Your corporation 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.
• You can provide public cloud to your customers while using a private cloud for internal IT.

Cloud computing is around shared IT infrastructure or the outsourcing of a company's technology.  It is important to scan your existing IT infrastructure, usage and requirements to determine which type of cloud computing can help you best achieve your goals.
