Private Cloud vs Public Cloud vs Hybrid Cloud – Which is best?

Advantages and Limitations of Cloud Platforms. When to choose what?

Cloud computing is the latest technology that is rapidly adopted by organizations to reduce their hardware and resources cost and enhance performance over the cloud infrastructure. There are different types of classifications, types and architectures in the cloud world. As per Forbes, almost 83% of the enterprise infrastructure, small to large, will be on cloud by 2022. If the cloud computing platforms need to be categorized then it can be segregated in three different types of models, namely:

  • Public Cloud Platform
  • Private Cloud Platform
  • Hybrid Cloud Platform

Further on the above mentioned cloud platforms, there are different deployment models which can be categorized as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). The infrastructure architecture of these deployment models can take different forms and offer a variety of features including virtualization, hyper converged models and much more.

Difference between the Cloud Platforms Vs On-Premise


In this post, we will explore the differences, advantages and limitations between varied cloud computing environments.

cloud platforms

Public Cloud

If you search online, you will find a lot of posts regarding Public Cloud and common names like Amazon Web Services (AWS), Azure and Google Cloud Platform (GCP). These are the public cloud platform service providers offering cloud space and infrastructure at monthly rentals. Some public cloud services are free while some are subscription based. Different types of services are provided on cloud including email, apps, storage, etc.

It completely depends on the business and their futuristic view to utilize the platform as per their need.

The best thing about public cloud is the vendor has to ensure the maintenance and upgrade of the infrastructure on cloud. There will be multiple tenants on single cloud platform and ensuring the space is appropriately provided to all the tenants as per their requirements is the responsibility of the vendor. Scalability, reliability, elasticity and security are the features of the public cloud platforms.

Several large brands across the globe have adopted public cloud platforms.

Limitations of Public Cloud Platform:

  • For large volume and resource usage, the cost can shoot up for organizations with vast infrastructure requirements.
  • Need to ensure highly secured infrastructure maintenance for sensitive data over cloud
  • Some of the regulatory compliance and control of infrastructure should be checked

Private Cloud Platform

private cloud

Any cloud platform that has been designed for the use of single organization is known as Private Cloud.

  • Private cloud is less accessible for mobile users due to security measures.
  • Private cloud when designed should be based on high volume and peak time of demand otherwise scalability issues can arise.

Hybrid Cloud Infrastructure

Hybrid Cloud

Any cloud platform which is combination of public and private cloud platform is known as the Hybrid cloud platform. The resources of the Hybrid clouds are orchestrated in such a way that it is tightly integrated to perform the required processes. The applications and software can share the resources between the private and public cloud. With such kind of setup, organizations can gain maximum amount of performance, scalability, cost and efficiency.
