What Are Public Private and Hybrid Cloud?

The organizations have various methods to deploy cloud service resources namely- public private and hybrid cloud. Each of the three has its own set of advantages related to their performances, cost-effectiveness, scalability, cloud security practices and reliability. It is up to the enterprises to decide which of the three should be deployed based on the individual requirements. This blog gives you an insight into what is public private and hybrid cloud and the differences between them in cloud computing technology.

Definition of Public Cloud:

Nowadays, cloud computing is a necessity for businesses. Cloud storage space and servers are now managed by third-party cloud service vendors and supplied over the web. Microsoft Azure, Amazon Web Services, Google Cloud, IBM Cloud are some popular examples of public cloud service providers. It is totally their responsibility to handle the cloud infrastructure like hardware, software and other supporting systems. The benefit of cloud computing is that enterprises can share their storage, hardware and network details with other cloud accounts or partners. Online accounts and services can be managed by web browsers. The online email, online storage, online Office applications and the development and testing environments are serviced by the public clouds.

Advantages of Public Clouds:

  • Costing Is Less – With public clouds, the enterprises will just have to pay for the services used in their businesses. There is no necessity to purchase any hardware or software with public cloud deployments.
  • Maintenance Cost Is Low – The maintenance of cloud storage infrastructure is done by the cloud service provider. The customers have to just enjoy the services offered by the service providers.
  • Unlimited Scalability- The enterprises can avail unlimited scalability resources for meeting their business requirements at a nominal cost.
  • Great Reliability- The service providers have a vast network of servers to address failure issues immediately; thus making the public cloud services reliable.

Definition of Private Cloud:

The private cloud can be hosted in two ways that are:

  • The entire storage data center is located in the enterprise itself
  • The third-party service provider is given responsibility to host the storage on behalf of the enterprise

Advantages of Private Clouds:

  • Highly Flexible- The enterprise can customize the cloud environment to meet their specific business requirements.
  • Much Enhanced Cloud Security- Since the cloud resources are not shared, there are better chances of security control.
  • Higher Scalability Features- The private cloud deployment provides better scalability.

Definition of Hybrid Cloud:

Hybrid cloud is a combination of public and private cloud. In this, higher efficiency can be achieved by migrating the data and programs from public to private or private to public; thus achieving higher flexibility with deployment options. Public cloud can be used to store high volume data but with fewer security requirements like web-based email clients. The private cloud can be used to store confidential data and critical operations like customer personal information. In the hybrid cloud, there is an option of cloud bursting. Here, the enterprise resources and software works on the private cloud till there is an absolute necessity or high demand to ‘burst through’ the public cloud. This helps the enterprise to acquire more computing resources on the cloud.

Advantages of Hybrid Clouds:

  • Data Control- The enterprises have the benefit of working in the private cloud for sensitive assets.
  • Flexibility- The enterprises can opt for public cloud whenever they need more cloud computing resources.
  • Cost-effectiveness- The enterprises have to pay only for the services used in the public cloud; they do not have to pay for the public cloud maintenance charges. There are costs required to maintain the private cloud.
  • Ease of Working- Shifting of data from cloud to another takes place in phases and that is a gradual process but not difficult if done properly.

Concluding Lines

Public private and hybrid cloud are very useful when enterprises understand their cloud computing requirements. The enterprises have to understand the technical concepts of the three and select the best. The security of data in the cloud cannot be compromised even when one among the three is selected. It is best that the enterprises go in for CASB solutions that add an extra layer of security into the confidential data; thus rendering them safe and secure.
