☁️ What is Cloud Computing?

Definition, Benefits, Applications & Best Practices

In today’s digital age, cloud computing has become the foundation of how businesses and individuals store, access, and manage data. From personal photo backups to large-scale enterprise software, the cloud is everywhere. This article explores what cloud computing is, how it works, its real-world applications, and the best practices for leveraging it effectively.

💡 Definition and Overview

Cloud computing refers to the delivery of computing services over the internet, including storage, processing power, databases, networking, software, and analytics. Instead of owning and maintaining physical servers or data centers, users can rent access to computing resources on-demand from cloud providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP).

🔍 Key Characteristics:

On-demand self-service: Access resources anytime without human interaction.
Scalability: Easily scale up or down based on demand.
Pay-as-you-go: Pay only for the resources you use.
Global accessibility: Access from anywhere via the internet.
