1. What is Cloud Computing?

Cloud computing is a way of delivering computing resources—like storage space, servers, databases, and applications—over the internet. Instead of buying hardware, customers rent it from a provider.

2. Why is Cloud Computing So Popular?

It makes companies operate smarter, quicker, and more inexpensively. No more expensive servers or storage space limitations—it’s all in the cloud.

Key Benefits:

1. Access your data anywhere
2. Pay only for what you use
3. Easily scale up or down
4. Great for remote and hybrid work

3. Types of Cloud Computing Services

Infrastructure as a Service (IaaS)

IaaS offers the basic cloud infrastructure: servers, storage, and networking. You own your entire IT infrastructure without any physical ownership of hardware.

Why use IaaS?

1. Create your own server environment
2. Scale resources immediately
3. Suitable for IT personnel and developers

Platform as a Service (PaaS)

PaaS provides a complete environment in which to develop and deploy applications. You only care about developing apps—the rest is handled.

Why use PaaS?

1. Save your development time
2. No server administration is needed
3. Ideal for app developers

Software as a Service (SaaS)

SaaS provides software applications via the web. There are no installs or updates to worry about—you simply log in and use the application.

Why use SaaS?

1. Off-the-shelf tools
2. Simple access from any device
3. Apt for heavier users (emails, documents, CRM)

4. Cloud Deployment Models

Public Cloud

Third-party vendors host and distribute it to numerous customers. It is the most common and lowest-cost kind.

Pros:

1. Low cost
2. Quick setup
3. Rapidly scales

Private Cloud

Shared by a single organization. Provides higher security and control.

Suitable for:

1. Confidential information
2. Such regulated areas as health and finance

Hybrid Cloud

Merges public and private clouds. Businesses retain confidential work privately and utilize public offerings for the remainder.

Why go hybrid?

1. More flexibility
2. Cost savings with control
3. Smooth handling of peak loads

Multi-Cloud

Uses multiple cloud providers. Helps avoid vendor lock-in and lets you pick the best services from each provider.

5. Major Benefits of Cloud Computing Services

Cost Efficiency

You avoid big upfront investments. Just pay for what you use and when you use it.

Scalability and Flexibility

Easily handle growth or seasonal spikes without buying more hardware.

Work Anywhere

All you need is an internet connection. Perfect for teams working remotely or across time zones.

Better Collaboration

Cloud tools allow real-time document editing and sharing, boosting productivity.

Built-In Security

Top providers offer:

1. Data encryption
2. Firewalls and threat detection
3. Disaster recovery plans
