The economic benefits of cloud computing have become so enticing that organizations have started to push their workloads to cloud computing services.

Today we have reached a stage where cloud has transitioned from being mere hype well into the mainstream IT space.

Here are a few good reasons why businesses have adopted cloud.

 It is driving cost efficiencies
•  Improving customer reach
•  Enabling new product development and innovation
•  Faster time to market

Yet, the expectations of most companies have not been met.

Till a few years ago, the Information Technology companies were focusing on public cloud computing. But when some businesses started having apprehensions regarding public cloud, the focus shifted to private clouds.

Did the outlook improve?

A survey conducted in different countries revealed interesting insights.

•  Above 30% of respondents confess that their IT requirements are not met by cloud providers.
•  Nearly half of the survey respondents are of the opinion that if their data is secured well they would greatly increase cloud adoption.

Fortunately, there is optimism in the horizon.

Today hybrid cloud deployment has become commonplace.

Numerous companies are leveraging a combination of private and public clouds based on their unique needs.

Some of the key considerations they factor-in include resources available, speed of execution, data security and more.

Before we discuss further here is a recap on the difference between public and private cloud.

Public clouds

A public cloud is a computing model wherein the service provider makes available to clients resources such as application and storage over the internet.

In other words, consumers via shared physical hardware pay only for the resources they use.

Such a cloud computing model is found attractive by small and medium businesses that have varying or fluctuating demands.

Public clouds are very large allowing users to scale their computer power up or down within a matter of minutes based on their requirements.

Private cloud

Private cloud is a cloud computing model where services are delivered through a proprietary architecture.

In other words, the infrastructure is delivered entirely to one client who is hosted either on-site or in the service provider’s data center.

As mentioned earlier, companies using either the public or private clouds, found cloud computing wanting in several aspects, especially with regard to security.

But now the hybrid cloud model is proving itself to be the right answer for enterprise IT.

This really is an offshoot of companies trying to make the best use of computing resources, whichever way they reside. After all this is what the hybrid cloud promises,

What then is hybrid cloud?

In straightforward terms, hybrid cloud allows an enterprise to combine public and private clouds to get the best of what each type offers.

Simply put, via hybrid cloud, companies aim to achieve the following:

•  Use the public cloud for non-sensitive operations
•  Use the private cloud for business critical operations.

By the above approach, enterprises hope to experience the cost and scale benefits of the public cloud and the security and control advantage of private clouds.

Here is a brief on how these advantages are achieved.

Cost savings

• By outsourcing certain workloads to public cloud providers, an enterprise’s capital expenses are reduced.
• By use of public clouds the overall CAPEX is reduced and so resource allocation is improved.
• Helps in optimizing spending during the different stages of a project lifecycle. A company can tap public clouds during development and testing operations and the private cloud during actual production.

Agility

•  Exponential increase in agility as the hybrid model offers the control available in private cloud and the rapid scalability of the public cloud.
•  Enterprise gets help for cloud bursting. This means the enterprise can use an application deployment model which runs in a private cloud, but bursts into a public cloud whenever there is a spike in e resource demand.

In conclusion, hybrid clouds offer superb flexibility for companies in terms of scalability while concurrently offering control and security.

But it must also be understood that there is no one- size- fits- all answer. Hybrid clouds can vary depending on organizational needs.

A hybrid environment can be complex involving both on-premise and public cloud hosting and hence companies must take into account additional security features that are typically needed when public clouds are made use of.
