Cloud Computing Models Explained: SaaS, PaaS, IaaS & Deployment | CompTIA Security+

Описание: The Wolf hates the Cloud because he can't find the server to blow it down. 🐷☁️🐺

In this episode of CompTIA Security+, Professor Piggy trots into the pasture of Cloud Computing. We break down the "Alphabet Soup" of cloud services (SaaS, PaaS, IaaS) and explain exactly who is responsible for security in each model.

We also cover the critical differences between Deployment Models (Public vs. Private) and how Multi-Cloud strategies stop you from getting locked in.

🔑 KEY TOPICS:
Cloud Computing Defined: Accessing resources remotely.
The "Black Friday" Lesson: How Amazon used elasticity to defeat failure.
Delivery Models:
SaaS (Software as a Service): Gmail, Google Workspace (Provider manages all).
PaaS (Platform as a Service): Web Hosting, AWS Lambda (You manage App, they manage OS).
IaaS (Infrastructure as a Service): Amazon EC2 (You manage OS & App).
Serverless Computing: Hiding the server management completely.
Deployment Models: Public, Private, Community, and Hybrid.
Multi-Cloud: Using AWS + Azure together to avoid vendor lock-in.
Shared Responsibility Model: The exam's favorite topic!

⚠️ EXAM ALERTS:
**SaaS vs. IaaS**: In SaaS, you manage *data only*. In IaaS, you manage the *OS and Apps*.
**PaaS**: Think "Developers." They write code, the provider handles the OS/updates.
*Hybrid vs. Multi-Cloud**: **Hybrid* connects different types (Public + Private). *Multi-Cloud* connects different providers (AWS + Azure).
**Community Cloud**: Shared by organizations with common goals (compliance/security).
