Cloud computing
                     Cloud computing
Cloud computing is the delivery of computing resources over the internet, or 
"the cloud", on-demand. It allows users to access computing resources like 
storage, databases, networking, and software without having to own and 
maintain physical servers and data centers. Instead, users pay for what they 
use, which can help lower operating costs and scale more efficiently. 
Some examples of cloud computing 
include: 
•Google Docs and Microsoft 365: Users can access work documents from any device 
with an internet connection.
•Email, calendar, Skype, and WhatsApp: Users can access their data from any device 
at any time.
•Zoom: A cloud-based platform for video and audio conferencing that records meetings 
and saves them to the cloud.
•AWS Lambda: Developers can run code for applications or back-end services without 
having to manage servers.
•Salesforce: A cloud-based customer relationship management platform for businesses.
Cloud computing 
• Some challenges of cloud computing include data security and 
privacy. Cloud users entrust their data to third-party providers, who 
may not have adequate measures to protect it. 
• There are four types of cloud computing: private clouds, public 
clouds, hybrid clouds, and multiclouds. There are also three types of 
cloud computing services: Infrastructure-as-a-Service (IaaS), 
Platforms-as-a-Service (PaaS), and Software-as-a-Service (SaaS).
