If you’ve been exploring cloud computing, data engineering, DevOps, or AI infrastructure, you’ve probably come across Amazon Web Services (AWS), the world’s most widely used cloud platform. But what is AWS and why is it used by millions of organizations? And more importantly, how can beginners start learning it in 2025?
This guide breaks down AWS in simple, practical terms so you can understand what it does, why it matters, and how to start building cloud skills that lead directly to AWS careers.
What Is Cloud Computing?
Before diving into AWS, it’s essential to understand cloud computing.
Instead of buying physical servers and maintaining hardware onsite, cloud computing allows companies to rent computing resources on demand — from storage to databases to entire machine-learning platforms. This shift is why modern businesses operate faster, scale globally, and innovate without huge upfront costs.
Cloud computing typically includes:
AWS plays in all three categories, making it the most complete cloud ecosystem available today.
What Is AWS?

AWS stands for Amazon Web Services, a collection of 200+ cloud services used to store data, host applications, build AI systems, manage networks, and much more. It offers everything a business needs to run digital systems without managing physical servers.
AWS is used because it provides:
- Global infrastructure
- Highly scalable resources
- Strong security
- Pay-as-you-go pricing
- Tools for startups up to Fortune 500 enterprises
This is why AWS is the market leader and the most in-demand skill in the cloud job market.
AWS Console: Your First Entry Into Cloud
The AWS Console is the web-based interface where you manage cloud services. You can:
- Launch virtual machines (EC2)
- Create storage buckets (S3)
- Build networks (VPC)
- Deploy apps
- Manage billing
- Set up IAM security
Beginners often find the AWS Console overwhelming, but with guided training, it becomes manageable — and essential if you’re pursuing AWS careers in cloud engineering, DevOps, MLOps, or data engineering.
