What is this book about?
Cloud Computing is the delivery of computing services (servers, storage, databases, networking, software) over the internet. This book is a technical deep dive into how businesses move away from physical hardware to virtual environments.
Key Topics Covered:
- Service Models: The “Big Three” of the cloud:
- IaaS (Infrastructure as a Service): Renting raw hardware (like Amazon EC2).
- PaaS (Platform as a Service): Tools for developers to build apps without managing servers.
- SaaS (Software as a Service): Using finished apps over the web (like Gmail or Netflix).
- Deployment Models: Understanding Public clouds (AWS/Azure), Private clouds (company-owned), and Hybrid clouds (a mix of both).
- Security & Privacy: This is a major focus. How do you keep data safe when it’s stored on someone else’s computer? The book covers encryption, identity management, and legal compliance.
- Virtualization: The technology that allows one physical server to act like 50 separate virtual computers.
