Cloud Computing has become the most essential part of any business that is dealing with massive data storage work. As technology is expanding at a rapid scale, the need and adoption of evolving technologies have become a vital necessity.
Talking about cloud computing then it can be defined as an on-demand availability of computer system resources when it comes to data storage and computing power excluding the direct involvement of the user. The major use of cloud computing lies in storing a massive amount of data on clouds securely and offering remote access to any work-related data. Cloud computing services should get adopted from any reputed firm for avoiding any kind of loss.

Now, let’s talk about the two most popular clouds – public cloud and private cloud –

Definition and Brief Information about Public Cloud 

The public cloud is a cloud computing model that delivers IT services using the Internet to all its clients. The services are usually based on premium or are free and at times they may be based on subscription-based model on how much volume of all the computing resources is consumed by a client.

Using a public cloud, all types of hardware, software, network devices are owned and handled by the cloud provider. Public cloud services are highly scalable and offer huge elasticity. The vendors of public cloud are the one who is involved in managing and maintaining and the development of the various computing resources that have been shared between various clients.

Top Features of Public Cloud 

  • Public cloud supports on-demand self-service which is a vital feature of cloud computing.
  • Managing servers is not an easy task and using the public cloud, you can decrease the downtime and easily maintain the server.
  • You can access data of the cloud and even can upload it to the cloud from anywhere using a device and a strong Internet connection.
  • The public cloud offers huge scalability that comprises many resources available to the cloud and users can access them seamlessly using the Internet.
  • It is very cost-effective to use the public cloud as they are easily available in the market and businesses can adopt it without much investment.

Beneficial Points of Public Cloud 

  • Highly cost-effective

The public cloud has a flexible pricing structure and this is considered as it’s one of the top benefits. Whether it is a small, mid-level, or a huge enterprise, all of them can benefit their business using the public cloud. Also, it provides a special benefit of pricing its services at an hourly basis that helps any level of business to benefit from the public cloud.

  • Easy to set up

The public cloud can be set up in just a few hours by the IT team. It requires only the internet and then it will be deployed and configured remotely using the cloud providing website.

  • It requires no maintenance

Talking about maintaining the public cloud then it is the role of a cloud provider who is responsible for managing and maintaining the hardware, software, and all kinds of networks in the cloud.

  • Offers enhanced security

With the evolving technology, companies are looking for more and more security aspects to adopt in their business. The public cloud has all the capability to offer enhanced security as it covers cybersecurity expertise, regular penetration testing, controlled access, and more such security measure that will keep your business safe and secure.

  • Saves time and money 

Being a public cloud user, the responsibility of managing the cloud hosting solution is taken by the cloud computing service provider. Also, it enables the developer for adopting agile workflow and this saves a lot of lead times that are required for testing and deploying new products. Talking about money, then it requires no capital investments, no maintenance, and update cost, and you can pay-as-you-use it.

Drawbacks of Public Cloud

  • Less controlling power

Outsourcing the technology to the public cloud will lose all the control from your hands. All types of configuration aspects that are related to the management of IT as well as physical and cybersecurity will be left to the people of the team who will get removed from performing the daily activities of your business. With the help of external support, it will become possible to manage all the activities.

  • Customization option is not available

There is no such way through which you can perform the customization of your resources or services. The public cloud does not provide or support any of the customization features.

  • Weak security measures

This is probably the main drawback of the public cloud that it offers weak security while managing the server activities on the cloud. It is always important for customers to keep sensitive information secure.

  • Less understanding of the back-end process

When it is about managing the physical security, then the cloud provider is responsible for managing it and enforcing the external firewall policies. The public cloud does not have any knowledge of handling the back-end data and how it will going to process for giving the expected results.

  • Less contract support 

The public cloud model has a separate contract for support as some of the providers does not offer the best service as per the expectation in an enterprise system.

Applications based on Public Cloud

  • Google App Engine
  • Azure Services Platform by Windows
  • Blue Cloud by IBM
  • Amazon Elastic Cloud Compute (EC2)

Understanding Private Cloud

The term Private in Private cloud itself is defining its nature that it will be dedicated to any single organization and will not share cloud computing resources with any other organization. It is a customized cloud to meet the business and security measures of a particular organization. In this, applications are being made available virtually on the cloud and they are not allowed to run on local servers.

Talking about the security measures of the private cloud, there is a firewall that is present to protect the private cloud from any unknown or unauthorized access. Only authorized users have permission to access the private cloud applications via VPN (Virtual Private Networks) or through the intranet of the client’s organization.

Highlighted features of Private Cloud 

  • Highly scalable and offers different levels of utilization through the size and maturity of data centers.
  • Offers high security and privacy measures making it the most secure cloud.
  • Private cloud services offer more control as the organization’s needs are restricted to the network solution only.
  • It offers enhanced reliability as the private clouds provide operating environments that are created virtually and offer high flexibility without any failures.

Using the private cloud, you can select an infrastructure and define your storage and networking characteristics, and this way, the system will meet its need.

The private cloud offers flexibility in allocating and reallocating resources dynamically when they are needed. You can perform this using the virtual machine and can scale up and scale down as per your requirements.

Drawbacks of Private cloud 

  • Private cloud is expensive 

The major disadvantage of private cloud is that because of its physical and periodic hardware and software needs, it is a little expensive cloud. Mostly, huge enterprises make use of the private cloud.

  • Maintenance is time-consuming 

The infrastructure of the private cloud takes too much time in setting up and that’s why it costs high. To avoid this thing, the company should depend on the hybrid cloud for avoiding all such problems.

  • Not much scalable

Talking about the scalability of private cloud, the deployment of private clouds by organizations will be performed by dealing with the same calculation and having the deployment of extensive physical infrastructure.

  • Deployment is a tough point 

A private cloud can get the extension from an internal hosted resource only. For maintaining the deployment, there will be the need of expert and qualified people from the organization.
