Public Cloud and Private Cloud- A Glance at Comparison

Migrating to cloud is one major advantage that firms could get to overcome the challenges associated the management of complex infrastructures.

Cloud deployment provides a range of options for the firms to choose from in line with their strategy and planning, budgetary allocations, among other factors to achieve enhanced scalability flexibility and control over internal operations.

Matching firms’ diverse requirements, cloud services are available in three different models namely: Private Cloud, Public Cloud and Hybrid Cloud.

While Public Cloud is operated by third-party providers and offers a large data storage, Private Cloud involves operation by a single organization with a single dedicated server. And, Hybrid Cloud is the combination of both Public and Private Clouds, where both work hand-in-hand.

Now, let’s take a deeper look into thin lines that are making a big difference between the Private and Public cloud models. Following aspects characterize a clear-cut comparison between the private and public clouds:

Planning and Expenditure

Public Cloud holds a significant role in this aspect as it eases budgetary challenges by offering flexibility to firms through its pay-as-you-go services, where the firms just have to pay for what they get. Public cloud deployment is definitely a time-saving and economical option for firms looking out for involving multiple long-term projects.

In the contrast, Private Cloud offers better advantages if your company is big and you are in need of dedicated resources/servers specific to your organizational requirements.

Data Security

Here, Private Cloud plays a major role.

Owing to its resource-sharing feature, Public Cloud sounds vulnerable to security concerns compared to the Private Cloud. In Private Cloud, the resources remain dedicated to a specific organization and can be decided in terms of control over data access and sharing.

Flexibility and Process Streamlining

Public Cloud offers a better flexibility to changes in resource management than the Private Cloud. As the Public Cloud involves multiple servers and shared resources, scaling the processes up or down is easier than in case of Private Cloud. Multiple and shared resources feature also helps Public Cloud easily manage multiple data streams. Whereas, Private Cloud requires additional hardware installations to do something beyond the existing set-up, which would consume time and involve additional expenditure.

Operational Performance

Private Cloud plays vital coming to operational performance ensuring high data access and transfer speeds. In the Private Cloud, having a dedicated resource in their own environment makes it easier for organizations to customize operational performance speed in line with their process requirements.

Whereas, in the Public Cloud, the operational speed will be low as the network performance here lies with third-party providers and majorly depends on their data transfer rate. Low data transfer, access and sending rates is one major constraint that firms looking for high connection speeds think of with regard to Public Cloud deployment.

Third Party Preferences

Owing to its pay-as-you-go feature, Public Cloud typically involves short-term contracts which can be exited at any point of time as subscription ends. Whereas, Private Cloud also includes maintenance contract with the service provider who might also require you to use hardware resources by certain manufacturers.

Pros and Cons

Upon proper implementation, a Private Cloud model can offer multiple advantages and can even meet almost all the requirements that are ideally possible with Public Cloud. These requirements include scalability, self-servicing, provisioning and configuring of Virtual Machines (VM) and management of computer resources.

However, some Private Cloud technologies, such as self-services and increased automation might also result in some complexions, for which, organizations may have to look for additional IT personnel to deal with data center infrastructure and adopt additional management tools.

Here is where, Public Cloud holds a special advantage over Private Cloud as most of the underlying challenges in the Public Cloud are maintained by Cloud providers.

Another potential advantage of Public Cloud over Private Cloud is cost-savings through the pay-as-you-go service offering. Whereas, in Private Cloud, the organization adopting the model will have to bear all costs right from deployment to maintenance.

Hybrid Cloud, a Model Out of Combination

Hybrid Cloud is a model that emerged out of Public and Private Cloud combination. In Hybrid Cloud, Private Cloud works hand-in-hand with the Public Cloud enabling the firms to manage their processes across the two models.  In other words, Public Cloud becomes as an extension to Private Cloud and emerges into a single uniform cloud in the Hybrid model. A hybrid deployment model ideally demands a high-level collaboration between the underlying software and services utilized by both the private and public clouds that make it.
