Difference Between Private Cloud and Public Cloud for Australian Businesses Explained

In almost every country today, especially in Australia, businesses are rapidly becoming digital and relying on private cloud. Most companies now use computers and the internet to make their work easier, faster and more secure. That is why “cloud computing” has become very important. Cloud computing is a system in which companies’ data and software are stored on the internet so that it can be used anywhere and at any time.

There are two main types of cloud computing: private cloud and public cloud. Both types of cloud computing keep data safe and provide easy access, but the methods are different. In public cloud different organisations use the same service via internet because it is cheaper and easier. On the other side, private cloud is premium services which is built for those organisations which has more security and control.

Nowadays, most businesses choose between these two according to their needs so that they can run their work better and more securely.

Public Cloud

Public cloud is a system in which computer-related services such as storage, servers, software, and databases are provided to people and companies via the Internet. In this, any person or business can easily use these services. This entire system runs on the Internet, so the user does not need to build their own expensive computer system.

Also, public cloud services provide large and well-known technologies such as Amazon Web Services, Google Cloud and Microsoft Azure. All these organisations operate data centers on large scale around the world where millions of user’s data is stored.

The biggest advantage of public cloud is that it is cheap, easy, and ready to use. Both small and large companies can benefit from it. The user only takes the service according to his needs and pays according to usage. That is why most businesses prefer public cloud today.

Characteristics of Public cloud

The biggest advantage of public cloud is that it is less expensive. Companies do not need to build their own expensive system, but they use the service via the Internet and only pay for what they use.

This system is very simple, so both small and large companies can use it without any difficulty. No special technical skills are required, because most of the work is handled by the service provider itself.

Another important feature of public cloud is that it is accessed via the Internet. This means that the user can use their data and service from any corner of the world, all they need is internet.

To put it in a example, it is like renting a house instead of building your own house. Similarly, in public cloud, instead of buying your own server, you use someone else’s server and pay as needed.

Private Cloud

A private cloud is a cloud system that is built for only one company or organisation. All the computer services, data, software, and servers in it are used only by that one organisation. No other company or general user can access this system.

Its biggest advantage is that it has very high security. Since data is not shared, sensitive information remains more secure. That is why large organisations, banks, government offices, and large companies prefer private cloud.

In a private cloud, the company has complete control over the entire system. It can also change it according to its needs and use it in a better way. But one problem with this is that it is quite expensive because it requires more resources and expert people to build, operate, and maintain it.

A private cloud is like a house built for only one family, which no one else can enter and all control is with this family.

Characteristics of Private cloud

A private cloud is a system that is built for only one company or organisation. In it, all the data and services are used only by that one organisation, so it has a lot of security. No other person or company has access to this data.

In a private cloud, the company has complete control. That is, it can run the system at will, change it, and use it according to its needs. That is why this system is considered more secure and reliable.

But one disadvantage of a private cloud is that it is expensive. It requires more money and resources to build and run it. Therefore, large organisations, banks, and government companies usually use it because they want more security for their sensitive data.

An example to understand this is that a private cloud is like your own house. Where only you have control and no one can enter without your permission.

Basic Difference Between Private Cloud and Public Cloud

1. Users

The biggest difference between public cloud and private cloud is who uses it. Public cloud is for everyone and every company. It can be easily used by all companies, small, large and new. That is why it is also called “cloud available to everyone”. On the other hand, private cloud is made for only one company or organisation. It does not involve any outside company. It is used especially by large organisations, banks or government offices so that their data is safe only with them.

2. Price

The price of public cloud is relatively low because many companies share the same system. The user pays only according to their needs, so even small businesses can easily use it. It runs on the “pay as you use” model. On the contrary, private cloud is very expensive because it is made entirely for a single company. In this, all the expenses have to be borne by a single organisation such as servers, security and maintenance etc. That is why only large organisations can afford it.

3. Security

Public cloud has good security but it is a shared system, so the data is in the same network with many users. Although large companies use advanced security, there is still some risk. In comparison, private cloud has much higher security because it is for only one company. It does not involve any other users. Therefore, sensitive data such as bank records or government information remains more secure and the risk of being hacked is very low.

4. Control

In public cloud, the company has limited control because the entire system is with the company providing the cloud service. The user can only use their service but cannot make major changes to the entire system. On the contrary, in private cloud, complete control is with a single company. And set up the system at will, update it, and use it as per her needs. That is why large organisations prefer private cloud so that they have complete freedom and control.
