What is Cloud Computing?

Cloud computing is a type of computing method that uses a network of remote servers hosted on the internet to store, manage, and process data, instead of  a local server or a personal computer. It allows users to access data from anywhere, at any time, without the need to install and maintain hardware or software. Cloud computing also offers expantion of capacity, allowing users to increase or reduce their computing resources as needed. This makes it an attractive option for businesses, as they can save money by only paying for the resources they use. Additionally, cloud computing can provide enhanced security, as data is stored in the cloud and can be accessed remotely.

Cloud computing vs traditional computing

 Cloud computing is mean different from traditional computing in that it does not require physical hardware or software to be installed on a user’s computer. Instead, cloud computing uses virtualized computing resources that are hosted remotely. This means that users can access their data from anywhere, as long as they have an internet connection. Additionally, cloud computing allows for greater scalability, allowing users to quickly increase or decrease their computing resources as needed. This makes it an attractive option for businesses, as they can save money by only paying for the resources they use.

Cloud computing models (public, private, hybrid)

 Cloud computing can be divided into three main models: public, private, and hybrid.

• What is Public cloud?  Public cloud services are provided by a third-party provider, such as Amazon Web Services, and are available to anyone who wishes to use them.

• What is Private Cloud? Private cloud services are hosted on a company’s own servers and are only available to that company’s employees.

• What is Hybrid cloud? Hybrid cloud services combine elements of both public and private clouds, allowing companies to take advantage of the benefits of both models. Each of these models has its own advantages and disadvantages, so it is important to choose the right one for your needs. 

Finally, it is important to consider the potential security risks associated with cloud computing. As data is stored in the cloud, it is vulnerable to cyber attacks and data breaches.
