What is Cloud Computing? 

On-demand availability of computer system resources, data storage, network, software, analytics, intelligence, and computing power is known as Cloud Computing. The main thing about Cloud Computing is that it is used without direct management by the user. 

Cloud Computing services are budget-friendly because cloud providers offer self-services on demand. You only pay for what you use. You can alter packages according to your requirements. It also offers data backup and recovery, security, and reduced network latency etc. That’s why industry giants are turning to cloud computing services to save their money and to get better services. 

Types of Cloud Computing 

Not all types of cloud computing are similar, they use different models and perform accordingly. Though, types of Cloud Computing is mainly divided into three parts- public cloud, private cloud, hybrid cloud. 

Public Cloud

Public Cloud is one of the three types of Cloud Computing. These clouds are usually operated by cloud service providers. Cloud providers handle the servers and provide computing resources, storage, servers and network. You as a customer will be allowed to access it through the web browser. All the hardware, the software would belong to the service providers. You only need the internet to use it. 

Public Clouds are in demand because it’s cheap and save a lot of purchasing cost. Public Clouds are managed and maintained by public cloud service providers. They bear the expenses and you get to pay for only CPU Cycle, bandwidth, storage, network or whatever other services you have used. One of the most important advantages is that all the employees of your company can use it through their systems. Public Clouds help a lot in group projects. However, the security of public cloud was questioned but don’t worry they are as safe as personal servers. Just choose the correct provider who uses IDPS (Intrusion Detection and Prevention Systems). 

Private Cloud 

The only difference between Private Cloud and Public Cloud is that Private Cloud is offered to a private internal network. Only an individual or selected members can access the servers. Private Cloud is usually used by companies who want privacy and security. Otherwise, all the other features like self-service, scalability, and browsing speed are similar to the public cloud. 

Private Cloud provides utmost security and privacy but your IT company will be responsible for maintenance as it is a private cloud and you will be in charge so you will have to bear the expenses too. It is somehow equal to traditional data centers or purchasing hardware and software to store data. 

There are two types of Private Clouds. First, IaaS (Infrastructure as a service) and second, PaaS (Platform as a service). Both types are preferred for different purposes. IaaS lets your company take advantage of the network, compute and storage. Whereas, PaaS, allows your company to use everything from cloud-based applications to enterprises applications. Go for the private cloud if you seek for confidentiality, privacy and want control over your systems. 

Hybrid Cloud 

Hybrid Cloud, third and last type of Cloud Computing. It is referred to the combination of both Private and Public Cloud. Hybrid Cloud provides the security of Private Cloud and infrastructure of Public Cloud. If you are using Hybrid Cloud then you can move your data from private cloud to public cloud or from a public cloud to private cloud. This switch happens according to your choice. In a Hybrid Cloud, ‘Cloud Bursting’ is also an option. You can understand it with the help of this example- you are managing an application, software or website on your private cloud but on a particular occasion, there is a spike in demand. In that case, you can immediately switch to the public cloud for better network, storage and speed. Overall, you can take advantage of both services. 

However, the choice between three types of Cloud Computing depends on your requirements and needs. You can go with anyone of them as per your demand.
