2. What is Cloud Computing? The Basics

The Simple Definition

Cloud computing means using the internet to access computing resources (servers, storage, databases, software) that are hosted on remote servers rather than on your own computer. Instead of owning and maintaining physical hardware, you rent these resources from a cloud provider.

Think of it like Netflix. You don't download movies to your computer and store them on your hard drive. Instead, Netflix stores all movies on their servers, and you access them over the internet whenever you want. Cloud computing works exactly the same way for businesses.

How Does Cloud Computing Work?

Cloud computing uses virtualization technology to divide physical servers into multiple virtual computers. Each virtual computer can run independently with its own operating system and applications. This technology allows cloud providers to serve thousands of customers from the same physical hardware.

Here's how the process works:

1. You request resources through the internet
2. Cloud provider allocates resources from their data centers
3. Resources are delivered instantly through the internet
4. You pay only for what you use
5. Resources scale up or down based on your needs

Key Characteristics of Cloud Computing

• On-demand self-service: Access resources anytime
• Pay-as-you-go model: Pay only for what you use
• Broad network access: Access from any device with internet
• Resource pooling: Multiple customers share the same infrastructure
• Rapid elasticity: Scale up or down in minutes
• Measured service: Track and pay for actual usage

3. Types of Cloud Services: IaaS, PaaS, SaaS, and Serverless

Cloud services are divided into different models based on how much responsibility you have versus the provider. Think of it like renting a house versus buying an apartment.

A. Infrastructure as a Service (IaaS)

IaaS provides you with raw computing infrastructure over the internet. You get access to servers, storage, and networking, but you manage the operating system, middleware, and applications yourself.

What the provider manages:

• Physical hardware
• Servers
• Storage
• Networking infrastructure
• Data center maintenance

What you manage:

• Operating systems
• Middleware
• Applications
• Data
• Security patches

Best For: Developers and companies that need flexibility and control over their infrastructure.

Examples:

• Amazon EC2 (AWS)
• Microsoft Azure Virtual Machines
• Google Compute Engine

Pricing Example (October 2025):

Instance Type	Provider	On-Demand	1-Year Reserved	Spot/Preemptible
t3.medium / e2-medium	AWS/GCP	~$30/month	~$18/month	~$9/month
B2s	Azure	~$30/month	~$17/month	~$3/month

B. Platform as a Service (PaaS)

PaaS provides a complete development environment in the cloud. You get tools, frameworks, and databases to build, test, and deploy applications without managing underlying infrastructure.

What the provider manages:

• Infrastructure
• Operating system
• Middleware
• Development tools
• Databases

What you manage:

• Your applications
• Data
• Some configuration

Best For: Developers who want to focus on writing code without managing servers.

Examples:

• Heroku
• Google App Engine
• AWS Elastic Beanstalk
• Azure App Service

Key Advantages:

• Faster application development
• Built-in tools for collaboration
• Automatic updates and patches
• Reduced time to market

C. Software as a Service (SaaS)

SaaS delivers complete, ready-to-use software applications over the internet. You simply access the application through a web browser—no installation needed.

What the provider manages:

• Everything! Infrastructure, platform, application, data, security

What you manage:

• Your data and user settings

Best For: End users and businesses that want to use applications without technical setup.

Common Examples:

• Productivity: Microsoft 365, Google Workspace, Slack
• Sales & CRM: Salesforce, HubSpot
• Collaboration: Asana, Monday.com
• Communication: Zoom, Microsoft Teams
• Email & Calendar: Gmail, Outlook

Global SaaS Market Size:
The global SaaS market is projected to reach over $300 billion by 2026, showing massive adoption across all industries.

D. Serverless Computing

Serverless is a newer model where you write code without thinking about servers at all. The cloud provider automatically manages all infrastructure, scaling, and resources.

How it works:

1. You write your function/code
2. Upload it to the cloud
3. Cloud provider runs it when needed
4. You pay only when your code runs
5. Provider handles all scaling

Examples:

• AWS Lambda
• Google Cloud Functions
• Azure Functions
• IBM Cloud Functions

Best For: Small, independent tasks that don't run constantly; saving costs on unused infrastructure.

Comparison Table: IaaS vs PaaS vs SaaS vs Serverless

Feature	IaaS	PaaS	SaaS	Serverless
What You Manage	OS, middleware, applications	Applications, data	Almost nothing	Code only
What Provider Manages	Hardware, virtualization	Infrastructure, tools	Everything	Infrastructure, scaling, OS
Customization	Maximum	High	Low	Limited
Control	High	Medium	Low	Very low
Complexity	High	Medium	Low	Low
Cost	Variable	Fixed or variable	Fixed (subscription)	Pay-per-execution
Best For	Startups, custom solutions	Developers, rapid development	Business users, enterprises	Microservices, tasks
Examples	AWS EC2, Azure VMs	Heroku, Google App Engine	Salesforce, Microsoft 365	AWS Lambda, Google Functions

11. Frequently Asked Questions (FAQ)

Q1: Is my data safe in the cloud?

A: Yes, in most cases safer than on-premises. Cloud providers invest billions in security, use military-grade encryption, and employ security experts. However, you must configure security correctly (proper IAM, encryption, access controls). Misconfiguration is the #1 cause of cloud security issues.

Q2: What's the difference between cloud and internet?

A: Cloud is a specific service delivered over the internet. Internet is the network. You can have internet without cloud (email), but not cloud without internet.

Q3: Can I access cloud services offline?

A: No, cloud services require internet. However, some applications can sync data to your computer for offline use (Google Docs offline mode). When internet returns, changes sync back.

Q4: Is cloud computing only for big companies?

A: No! Cloud is perfect for small businesses and startups. In fact, 70% of small businesses use cloud computing. Cloud's pay-as-you-go model makes it affordable for all sizes.

Q5: How much will cloud cost me?

A: Ranges from free (free tier) to thousands monthly. An average small business pays $200-500/month. Large enterprises pay millions. Use pricing calculators before choosing.

Q6: What if cloud provider shuts down?

A: Very unlikely with AWS, Azure, Google Cloud. But you should:

• Back up important data
• Document your setup
• Use standard formats (don't use proprietary tools exclusively)
• Have exit plan

Q7: Can I switch cloud providers easily?

A: Difficult but possible. Switching costs time and money. Prevent vendor lock-in by using standard technologies (Docker, Linux, open-source tools) rather than proprietary services.

Q8: What's the learning curve?

A: Moderate. Basic cloud concepts take 1-2 weeks to understand. Mastery takes months of hands-on practice. Certification typically requires 3-6 months of study.

Q9: Do I need to learn coding for cloud?

A: No. You can use cloud services without coding (SaaS applications). But if you deploy applications or use IaaS, basic understanding of servers and networking helps.

Q10: What's the "serverless" buzzword about?

A: "Serverless" means you write code and cloud provider handles all server management. You don't think about servers—just write functions and upload. Pay only when code runs.
