Cloud computing has become an outstanding way to provide IT [Information Technology] infrastructure to all customers. It’s not a group of products that get implemented.
There are several types of cloud computing, such as public and private cloud and hybrid cloud. Out of the three, the public and private clouds are more popular.
In this post by Hero Vired, we will provide a detailed explanation of the public and private cloud, their differences, and many other things.

What is Cloud?
Cloud is known as the “network” or the “internet”. It’s a technology that utilizes the remote servers present on the internet to access, manage, and store data only instead of the local drives.
This “DATA” can be all types of things, such as video, audio, documents, pictures, files, etc. People also utilize the IaaS PaaS SaaS, which is cloud-hosted servers. Besides that, through cloud computing, you can conduct the following tasks:
- Stream audio and videos
- Develop new services and applications
- Recover, backup and store data
- Host websites and blogs
- Deliver software on demand
Importance of Cloud
Before the cloud existed, all businesses stored their software and data on servers and hard drives. Bigger companies require bigger storage space. This method of treating data cannot be done quickly.
For instance: When people get to know about your business, and you receive a massive amount of orders online, the servers will crash.
This clearly shows that cloud computing is vital for all businesses to operate smoothly online. But wait! Businesses are not the only ones who benefit greatly from the cloud.
This technology also plays an important part in the lives of people across the globe. If you observe closely, you’ll find that cloud services are utilized by everyone regularly. Some of these examples are
- Updating social media
- Watching new series
- Check the balance in the bank
Experts of DevOps & Cloud Engineering have also pointed out that people use applications hosted by cloud services. People access these applications through the internet connection instead of installing them on their devices or hard drives.
What is Public Cloud?
Through the public cloud, all the IT solutions are provided through the internet. This popular cloud computing model offers a diverse range of options in terms of computing resources and solutions to address all business needs.
When you compare between public and private clouds, you will find that the public cloud has much more scalability and high elasticity. It also comes with a subscription-based pricing option, which is pretty affordable.
What is Private Cloud?
A private cloud is pointed towards any kind of cloud solution which is used by a single company. The only difference between public cloud and private cloud is that, in a private cloud, you don’t share the resources of cloud computing with other companies.
You can easily customize the private cloud to meet all your security and business needs. It will provide a high level of control and visibility in the infrastructure. It will also help businesses to run all the sensitive IT tasks without compromising on the performance and security of the on-premises information centers.
