Cloud computing has transformed the way individuals and businesses access, manage, and store data. Instead of relying solely on physical infrastructure, cloud computing delivers computing services—like servers, storage, databases, networking, software, and more—over the internet (“the cloud”).

🔹 Key Cloud Service Models

1. IaaS (Infrastructure as a Service) – Rent IT infrastructure (like servers and virtual machines) on a pay-as-you-go basis.

2. PaaS (Platform as a Service) – Provides a platform allowing developers to build, test, and deploy applications without managing the underlying infrastructure.

3. SaaS (Software as a Service) – Access software applications via the web, without worrying about installation or maintenance (e.g., Gmail, Office 365).

🔹 Deployment Models

Public Cloud – Services delivered over the internet by third-party providers (e.g., AWS, Azure, Google Cloud).

Private Cloud – Cloud infrastructure operated solely for a single organization.

Hybrid Cloud – Combines public and private clouds to allow data and apps to move between them for greater flexibility.
