Basic Question About Cloud-Computing🌨️❓

1)What is Cloud Computing? ☁️

->Cloud Computing is delivering the on demand computing services including servers,data storage,database,networking and software over the internet ,pay as you go.

Example → "When you use Google Drive to store your files, you're using cloud computing 📁☁️! Google provides storage services over the internet 🌐, and you don't need your own server to save your data 💻. Isn't that convenient? 😊"

"Google Drive = Cloud Computing 📁☁️! Store files online, no server needed 💻. Convenient, right? 😊"

2)Why do we need Cloud Computing? 🤔

→ Cloud computing helps us use storage, apps, or powerful computers over the internet without buying them. 💻🌐 It’s flexible, saves money 💰, and works from anywhere 📍. You can also increase or decrease resources as needed, making it perfect for growing businesses or changing needs. 📈

Real-Time Example:
A school 🏫 needs to host online classes for many students. Instead of setting up expensive servers, they use Google Meet 🖥️, a cloud-based tool. It works for all students, and the school doesn’t need to worry about managing or upgrading hardware. 🚀

3)What are the Advantages of Cloud Computing? 🌟

→ Save money 💸

1. Work from anywhere 🗺️

2. Store lots of data 📁

3. Keep data safe 🔒

4. Collaborate easily 👥

5. Get latest technology 💻

6. Other Benefits

   • Scalability (grow as you need)

   • Flexibility (access from any device)

   • Reliability (less downtime)

   • Automatic Updates (stay current)

   • Environmentally Friendly (reduce carbon footprint)

4)What are the Different Types of Cloud? 🌥️

Types of Cloud Computing Service Model 🛠️

1. Infrastructure as a Service (IaaS) 📦

   • Provides virtual computers, storage, and networks over the internet.

   • Example: Amazon Web Services (AWS) helps businesses with scalable storage and computing power.

2. Platform as a Service (PaaS) 🛠️

   • Offers a platform to build, run, and manage apps without worrying about hardware or infrastructure.

   • Example: Google App Engine lets developers easily create and deploy apps.

3. Software as a Service (SaaS) 📊

   • Delivers software online, usually on a subscription basis.

   • Example: Microsoft 365 provides Office apps like Word and Excel that work online.

4. Function as a Service (FaaS) ⚡

   • Lets you run small pieces of code triggered by events, without needing to manage servers.

   • Example: AWS Lambda runs code when something happens, like a file upload.

Types of Cloud Computing Service Model

1. Public Cloud 🌐

   • Services are available to everyone over the internet and shared across multiple organizations.

   • Example: Microsoft Azure provides cloud services that businesses of all sizes can access.

2. Private Cloud 🔒

   • Dedicated to a single organization, offering more security and control.

   • Example: IBM provides private cloud solutions for companies that need to protect sensitive data.

3. Hybrid Cloud 🌈

   • Combines both public and private clouds, letting you share data and apps between them.

   • Example: A company might use AWS for general tasks and a private cloud to store sensitive customer data.

4. Community Cloud 🤝

   • Shared by several organizations with similar needs, often in the same industry.

   • Example: A government cloud used by various agencies for compliance and secure data sharing.

Each model offers different levels of flexibility, security, and cost-efficiency to fit the specific needs of an organization.

4. pwd 📍

   • Shows the full path of your current location (working directory).

   • Great for knowing where you are in the system.

5. history 🕒

   • Displays a list of all the commands you've used before.
