Step 1: Understand the Core of Cloud Computing
Cloud computing is the delivery of computing resources—servers, storage, databases, networking, software—over the internet. Instead of owning physical hardware, you rent it from cloud providers like AWS, Azure, or Google Cloud. This approach provides flexibility, scalability, and global distribution.
Key Benefits
- On-demand resource provisioning
- Pay-as-you-go billing
- High availability and elasticity
- Global infrastructure at your fingertips
Service Models
- IaaS: Virtual machines, networking, storage
- PaaS: Managed application platforms
- SaaS: Fully managed software services

Step 2: Launch Your First Cloud Instance
Most cloud providers offer a simple way to spin up your first virtual machine (VM). Here's the essential workflow:
# Example: Deploying an EC2 instance on AWS (pseudo-steps)
1. Log in to console.aws.amazon.com
2. Navigate to EC2
3. Click "Launch Instance"
4. Choose an AMI (e.g., Amazon Linux 2023)
5. Select instance type (t2.micro for free tier)
6. Configure networking & security groups
7. Launch and connect via SSH
Once launched, you can connect to the instance and install software, deploy apps, and configure storage or networking components.
Step 3: Understand Cloud Deployment Models
There are three major deployment models to be familiar with:
- Public Cloud: Fully managed by providers; ideal for scaling fast.
- Private Cloud: On-premises or dedicated environments.
- Hybrid Cloud: The best of both worlds; combine local infrastructure with on-demand cloud resources.
