The cloud is a booming industry and holds significant economic advantages, including better utility, computing and scalability. As a result, corporations are moving their business critical systems into the cloud. But a question always keeps popping up, “What choice do we opt for – public, private or hybrid cloud?”

But to address the question, let us first define the different methods of deploying your software and hardware infrastructure on the cloud.

Public, Private, and Hybrid

Public Cloud: The public cloud is one of the more common cloud computing models available in the market. The service provider of a public cloud makes resources (software and data storage) available over the internet. Cloud services in this model are provided in an environment that is virtualized. The public cloud is constructed using physical resources that are pooled, shared and accessible over a public network.

Private Cloud: A private cloud enables a consumer to reap the benefits of cloud computing, which includes self-service, automation, consolidation and metered usage. Private players allow this behind the safety of their firewall, which is usually on their own virtual private network.

Hybrid Cloud: The environment in which an organization provides and manages some resources in-house and provides for other resources externally.

Simply based on the definitions, one seems to arrives at the conclusion that a dynamic hybrid cloud provides us with the best of both worlds (public and private) and presents a dedicated hosting that can help build a perfect solution for unique requirements. But let us delve a little deeper.

How to Choose

Public Cloud: Organizations that are not looking for a very specific kind of infrastructure, as well as security, should opt for a public cloud. By going this route, organisations can utilise the benefits offered by public clouds and hence, add efficiency to their operations. The public cloud can be of great use if an organisation plans to store and process non-sensitive information.

Private Cloud: Organizations looking forward to store and process sensitive data and/or private data should look forward to utilising the private cloud for all their cloud purposes. Companies that are required to follow certain regulations due to their handling of private information can also use and benefit from some of the advantages that are delivered by private cloud computing. Be prepared for increased costs, though.

Hybrid Cloud: As the name suggests, this combines characteristics from the other two cloud deployment systems. Using a hybrid cloud could be the best choice for companies in certain exceptional events. For instance, an organization could utilize the hybrid cloud in combination, to provide some financial businesses with data storage for confidential client data within a private cloud, while allow collaboration on different projects in the public cloud, where security and confidentiality is not a concern and data or applications can be accessed by multiple users.

Cloud computing is a form of computing which relies on sharing a pool of physical or virtual resources. It does not involve deploying any hardware and this is what makes it cost efficient and helps companies boost their productivity. Irrespective of what deployment method you choose, it’s time your business got on the cloud.
