Introduction to Cloud Computing and Cybersecurity: A Beginner's Guide

Cloud computing and cybersecurity are two pillars of modern technology. This guide introduces the basics for beginners, helping you understand how they work together to protect data and enable innovation.

☁️ What is Cloud Computing?

Cloud computing delivers computing services—servers, storage, databases, networking, software—over the internet. Instead of owning hardware, you access resources on-demand, paying only for what you use.

🛠️ Cloud Service Models

IaaS (Infrastructure as a Service): Rent virtual servers and networks (e.g., AWS EC2).
PaaS (Platform as a Service): Deploy code without managing infrastructure (e.g., Heroku).
SaaS (Software as a Service): Use software via the web (e.g., Gmail, Google Docs).

🏢 Cloud Deployment Types

Public Cloud: Shared resources over the internet (e.g., AWS, Azure).
Private Cloud: Dedicated resources for one organization.
Hybrid Cloud: Combines public and private clouds for flexibility.

🔐 What is Cybersecurity?

Cybersecurity protects systems, networks, and data from digital attacks. As more data moves to the cloud, security becomes even more critical.

⚠️ Common Cloud Security Threats

Data Breaches: Unauthorized access to sensitive data.
Insecure APIs: Poorly secured APIs can be exploited.
Misconfigurations: Incorrect settings can expose data.
Insider Threats: Employees or contractors may leak or steal data.

🛡️ Best Practices for Cloud Security

Use IAM (Identity and Access Management): Limit access based on roles.
Enable MFA (Multi-Factor Authentication): Add extra protection beyond passwords.
Encrypt Data: Protect data at rest and in transit.
Monitor and Audit: Use cloud-native tools to track activity.
Apply Zero Trust: Always verify, never trust by default.

🏠 Shared Responsibility Model

Cloud providers secure the infrastructure, but you must secure your apps, data, and user access. Think of it like renting an apartment: the building is secure, but you still need to lock your door.
