AWS
AWS Cloud Practitioner Basics
Core AWS services, regions, IAM, and pricing models for your first certification.
Cloud computing delivers computing resources — servers, storage, databases, networking, and software — over the internet on demand. Instead of buying and maintaining physical hardware, you rent what you need and scale instantly. Companies like Netflix, Spotify, and startups worldwide run on cloud infrastructure.
💡 Tip: Both AWS and Azure offer free tiers for students. Create an account, explore the console, and launch a free virtual machine to get hands-on experience without spending money.
Cloud Concepts Roadmap
Week 1
What Is Cloud Computing?
On-premises vs. cloud, public vs. private vs. hybrid cloud, and the benefits: scalability, cost savings, and global reach.
Week 2
Cloud Deployment Models
Single-tenant vs. multi-tenant, regions and availability zones, and how redundancy keeps services online.
Week 3
Cloud Economics
Pay-as-you-go pricing, reserved instances, spot instances, and how to estimate monthly cloud costs.
SaaS, PaaS & IaaS Roadmap
SaaS
Software as a Service
Ready-to-use applications accessed via browser — Gmail, Slack, Salesforce. The provider manages everything.
PaaS
Platform as a Service
Deploy apps without managing servers — Heroku, Google App Engine, Azure App Service. Focus on code, not infrastructure.
IaaS
Infrastructure as a Service
Rent virtual machines, storage, and networks — AWS EC2, Azure VMs, Google Compute Engine. Maximum control and flexibility.
AWS Basics Roadmap
Phase 1
AWS Console & IAM
Navigate the AWS Management Console, create IAM users and roles, and understand the shared responsibility model.
Phase 2
Core Services
EC2 (compute), S3 (storage), RDS (databases), VPC (networking), and Lambda (serverless functions).
Phase 3
First AWS Project
Launch an EC2 instance, host a static site on S3, and set up a basic CI/CD pipeline with CodePipeline.
Azure Basics Roadmap
Phase 1
Azure Portal & Subscriptions
Explore the Azure portal, understand resource groups, subscriptions, and Azure Active Directory basics.
Phase 2
Core Services
Azure Virtual Machines, Blob Storage, Azure SQL, App Service, and Azure Functions overview.
Phase 3
First Azure Project
Deploy a web app to Azure App Service, connect to Azure SQL, and monitor with Azure Monitor.
📝 Note: Cloud certifications like AWS Cloud Practitioner and Azure Fundamentals (AZ-900) are excellent entry points. They validate your knowledge and are recognized by employers worldwide.
