Cloud Computing Essentials
Cloud Computing Essentials refers to the fundamental concepts, technologies, and services that enable the delivery of computing resources over the internet. It includes understanding cloud service models such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), as well as deployment models like public, private, and hybrid clouds. Key topics also cover scalability, security, virtualization, cost efficiency, and on-demand resource accessibility.

❓ Frequently Asked Questions
What is cloud computing in simple terms?
Cloud computing delivers computing resources over the internet on demand (servers, storage, apps) and is billed by usage, so you don't need to own or manage hardware.
What are IaaS, PaaS, and SaaS?
IaaS provides virtualized computing resources (VMs, storage); PaaS offers a platform for developing and deploying apps; SaaS delivers software applications accessed over the internet.
How do the main cloud deployment models differ?
Public cloud uses shared infrastructure from a provider; private cloud is dedicated to a single organization; hybrid combines both to move workloads between them.
What is elasticity vs scalability in cloud computing?
Scalability is the ability to add resources to handle growth; elasticity automatically adjusts resources up or down in real time as demand changes.
What is the shared responsibility model?
The provider secures the cloud infrastructure; you remain responsible for securing your data, identities, and cloud configurations.
