Cloud Computing+50 
Cloud computing is a technology that enables users to access and store data, applications, and services over the internet instead of on local computers or servers. It offers on-demand resources such as storage, processing power, and software, which can be scaled according to user needs. This approach enhances flexibility, reduces IT costs, and allows businesses and individuals to collaborate and work remotely with greater efficiency and security.

💡 Key Takeaways
- Define cloud computing and how it delivers data, apps, and services over the internet instead of local storage.
- Describe on-demand resources such as storage and processing power, and how elasticity lets resources scale with demand.
- Identify the three main service models (IaaS, PaaS, SaaS) and what each offers in terms of control and responsibility.
- Explain deployment models (public, private, hybrid) and when each is typically used.
❓ Frequently Asked Questions
What is cloud computing?
Cloud computing delivers computing resources—like storage, processing power, and software—over the internet on demand, with scalable resources that can grow or shrink as needed.
What are the main cloud service models (IaaS, PaaS, SaaS)?
IaaS provides virtualized hardware (servers and storage); PaaS offers a platform to develop and deploy apps; SaaS delivers software accessed online.
What are the common cloud deployment models?
Public cloud uses shared infrastructure; private cloud is dedicated to a single organization (often on‑premises); hybrid cloud combines public and private clouds.
What are the benefits and considerations of cloud computing?
Benefits include on‑demand resources, scalability, and potential cost savings. Consider security, compliance, data residency, and potential vendor lock‑in.
