☁️ What is Cloud Computing?
Cloud computing refers to delivering various computing services—such as servers, storage, databases, networking, software, and analytics—over the internet (called "the cloud"). Instead of owning physical hardware or software, you rent these resources from cloud providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud.
This model allows users to access powerful computing resources anytime, anywhere 🌍, without worrying about managing infrastructure.
🛠️ Types of Cloud Computing
1. Infrastructure as a Service (IaaS)
Provides virtualized computing resources over the internet.
Users can rent virtual machines, storage, and networks.
Examples: Amazon EC2, Microsoft Azure Virtual Machines
2. Platform as a Service (PaaS)
Offers a platform for developers to build, test, and deploy applications without managing the underlying infrastructure.
Examples: Google App Engine, Heroku
3. Software as a Service (SaaS)
Delivers software applications over the internet on a subscription basis.
Users can use the software without installation or maintenance.
Examples: Gmail, Dropbox, Microsoft 365
