What is cloud computing?

Cloud computing is the delivery of computing services over the internet instead of using local hardware. This includes storage, servers, databases, networking, and software.

Instead of saving files only on your personal computer, cloud services store data on remote servers located in data centers. You can access this data from anywhere with an internet connection. Examples include Google Drive, iCloud, and Microsoft OneDrive.

There are three main types of cloud services:

• IaaS (Infrastructure as a Service) – Provides virtual machines and storage.
  
  

• PaaS (Platform as a Service) – Provides development environments for building applications.
  
  

• SaaS (Software as a Service) – Provides software through a web browser.
  
  

Cloud computing allows businesses to scale resources easily without buying expensive hardware. It also improves collaboration because multiple users can access the same data.

However, cloud systems depend on internet access and require strong security measures to protect sensitive information.

In summary, cloud computing allows users to access computing resources and storage online instead of relying only on physical devices.
