Public Vs Private Cloud Pros and Cons

With companies migrating their data to the cloud, many service providers are setting their feet into the cloud computing business. Cloud computing is categorized into Private and public. There are many differences between the former and the latter. So, before delving into Public Vs Private Cloud Pros and Cons, it’s really important to understand their differences. Let's start.

Understanding Public Cloud

The public cloud refers to an organization similar to Microsoft Azure or Amazon AWS offering a data center comprised of powerful computing devices and more storage than we can comprehend in which you lease the space and power. These can be used as individual applications, software that is part of the Software As A Service (SaaS) model, an environment or platform that is part of the Platform As A Service model (PaaS), and so on. Alternatively, you could use it to host all your business applications in a cloud-based, completely cloud-based structure.

The most important thing to know about the benefits of a public cloud is understanding two facts. The first is that your company doesn't have the hardware to use and is not the sole owner of utilizing the hardware.

The company will provide the hardware and, in some cases, a degree of software, be it just a basic OS or complete software suite that you can rent and modify to suit your needs within the limits they put in place. Webmail is a cloud-based email service; Dropbox Cloud storage is cloud-based in addition, its Adobe Marketing Cloud is exactly what it's called (for instance).

Understanding Private Cloud

In a way, they are to a "traditional" way of doing business. Contrary to public cloud services, they are controlled by you, and you own the hardware. This means that your company sets up a network station that runs servers, business software, and any other software needed to run your business.

In this case, you'll typically need a managed service provider to take care of maintenance for your infrastructure or a dedicated and large IT staff to ensure your infrastructure is functioning smoothly. Also, you need specific services from your utility, including a guarantee of reliability from your Internet service provider and alternative power sources for backup for the data center.

Additionally, you require a robust backup system in the event of a failure, adequate cooling, and regular maintenance and upgrades. It's a lot of work, especially for a smaller company that doesn't have a team of network architects.

Now that you understood the difference and their types, it’s time to know the Public Vs Private Cloud Pros and Cons.

Private Cloud Pros to consider

The private cloud system is an entire infrastructure offered to only one customer or organization.

  • Controls: The private cloud offers more effective controls for users, data, and other information assets.
  • Cost: Initial hardware investment is high regarding infrastructure on-premises.
  • Secure: Cloud is a service that belongs to a single user. This means that the cloud infrastructure and system can be set up to offer safe levels.
  • High-Performance: Most of the time, private clouds are set up within the firewall of an intranet's network, ensuring efficiency and excellent internet performance.
  • Simple Customization: Its hardware, as well as other resources, can be easily modified by the organization.
  • Compliance: Compliance can be easily achieved through private cloud services.

Public Cloud Pros to Consider

In cloud services, resources are shared by several clients. The service provider is responsible for all services.

  • Easy and simple: Public cloud services are accessible via the internet and are very easy to install.
  • The Cost: Initial cost is low, or even zero, which is one of the noted pros of public cloud.
  • Time: The IT services and resources are immediately available, saving the business time.
  • No maintenance is required: The cloud service provider is responsible for maintaining the infrastructure and hardware. IT personnel within the internal IT department do not have a charge for infrastructure maintenance.
  • No contracts: There is no long-term commitment to the service provider, as the public cloud is typically a pay-as-you-go model.

Public vs Private Cons

Though both these computing technologies have some advantages, they both have their own set of limitations. Here is a quick comparison of Public vs Private Cons.

1. Cost

Costs can be substantial in the event of constructing an on-premise cloud. The operating cost will include the cost of personnel as well as periodic upgrades to the hardware. If the cloud is a private cloud that is outsourced, the operating costs will be based on per-resource use and are subject to alter depending on the choice of service providers.

2. Lacks proper controls

The client is not in control over the data or infrastructure. There are concerns about security and privacy for data. The policies of the service level and their compliance are strictly adhered to by the company providing the services.

3. Under-utilization

In some cases, the resources that are subscribed to may be over-utilized. Thus, optimizing the utilization of all resources can be a problem.

4. Performance

The efficiency of the network is contingent upon the speed of the internet connection. If you do not have the best internet connectivity, you might not be capable of accessing your data stored on the cloud, regardless of the kind of cloud.

5. Capacity ceiling

Due to limitations in physical hardware by the service provider, there could be a ceiling on the capacity to manage a limited number of storage servers.

6. Weak Security

Because the resource on hardware is shared among several customers, IT security issues are more extensive, and sensitive data can be a target for loss.

7. Vendor lock-in

This could be a significant limitation to adopting a private cloud, particularly when the infrastructure and hardware are outsourced. This is a method where the client's company must remain with the same provider, preventing the client from moving to a different vendor.

Public Vs Private Cloud Pros and Cons – Conclusion

A majority of smaller and mid-sized companies will discover that a cloud service offered by a public provider is the best choice for them to find a suitable combination of the advantages of cloud computing as well as the costs associated with running infrastructure and the possibility of scaling up when the company expands.

Larger enterprises often find the hybrid configuration is best, and sometimes a certain business process requires running on proprietary hardware or in an environment that public clouds do not support. It's more affordable and simpler to set up local cloud hardware rather than paying for expensive configurations.

The biggest companies - such as Microsoft or Amazon themselves - discover that private cloud is the best solution. If you have these resources, purchasing and managing your own multi-million-dollar private cloud isn't a problem.

Public Vs Private Cloud Pros and Cons

Frequently Asked Questions

Is Public or Private Cloud Better?

The private cloud can be the ideal alternative if your infrastructure and data require the most secure security on various levels. If you choose private, you do not rely on third parties to control the environment. Remove third parties from the equation, and security improves.

Why is Public Cloud better than private cloud?

There is no requirement to buy software or hardware; you only pay for the services you use. The service provider takes care of the maintenance. Near-unlimited scalability--on-demand resources are available to meet your business needs.

Why would someone use a private cloud?

Private Clouds provide the same level of control and security as traditional infrastructure on-premises. Here are some of the reasons that businesses choose to use private cloud computing Security The security of private cloud computing is improved because the traffic to a cloud that is private is limited to transactions of a company.

What is best advantage of private cloud?

In contrast to other cloud platforms, there is no sharing of resources, and you can enforce strict security measures to block the use of your cloud by unauthorized users from using the cloud. Because it is only a single client, you can divide the cloud into multiple departments within your business.
