Public vs. Private Cloud Computing Model

In this modern world, everyone is happy and agreed with the benefits of cloud computing which include the basic benefits such as instantaneous provisioning, virtualization and the ability to expand the server and scalability and more.

The deployment of public cloud happens through the web server. The deployment systems have no issue to compliance and security for larger organizations. For the private cloud computing, a single tenant environment is dedicated to the storage, network and hardware for a single company or client. The public cloud network is defined as multi-tenant environment where you have the ability to slice an environment which is shared with a number of clients. Let’s have a deep understanding of the concept:

Public Cloud Computing

When we talk about the public cloud networks such as Amazon EC2 and others, there are several trade-offs.

  • Utility model: The public clouds are meant to deliver payments per model delivery and you can pay per hour for the resources you are managing. This is one of the economical processes to complete the tearing and spinning of the development servers.
  • No contracts: The utility model is quite beneficial when you are paying the resources on an hourly basis and if you want to shut down the server at any time, there is no such contract regarding the ongoing use of the server. That means you will be paying for what you use.
  • Hardware: The public network requires a multi-tenant environment and it shares the same hardware, network devices and storage. Meeting the requirements such as SOX and PCI is not possible in the public cloud.
  • Management: The cloud server is self-managed. The advantage for the technical buyers is to setup and manage the details of the servers. It’s not beneficial for those who are working over a managed system.  Most of the deployments of public clouds are usually over web servers and development servers where the compliance and security of huge organizations and the customers is not an issue.

Private Cloud Computing

On the other hand, private cloud hosting is defined over a single-tenant environment where you have the privilege of hardware, networks and storage which are only dedicated to a single client.

As compared to public cloud networks, there is private cloud computing trade off too. Let’s have a look at them:

  • Security: Private clouds are only dedicated to a single organization. Only the data storage, hardware and networks are designed which assure a higher level of security that cannot be accessed by the other clients remaining in the same data center.
  • Compliance: PCI and HIPAA compliance cannot be delivered over a public cloud network but it can be delivered over a private cloud network because the network, hardware and storage configuration is only dedicated to a single client which is easy achieve in private cloud networks.
  • Personalization: The hardware, network and storage data performance can be customized in the private cloud.
  • Fusion Deployments: For running a high speed database application, a dedicated server is required so that the hardware can be integrated into a private cloud to get hybrid solutions between the dedicated and virtual servers. This cannot be achieved in a public cloud environment.

The private clouds are not delivered using a utility model as a public cloud network just because the hardware is dedicated. The private clouds are basically preferred by large and mid-sized organizations because they meet the security requirements and compliance requirements of the large scale organizations and their consumers. There were some of the best solutions for cloud servers. You can deploy a public or private cloud network according to the needs of a business. In order to stay updated about both of them, stay in touch with the tech news.
