Why Cloud Computing Matters

The Invisible Infrastructure

Right now, as you read this, cloud computing is handling your email, streaming your music, syncing your files, backing up your photos, and powering the AI assistants you use every day. It’s running your company’s HR system, your bank’s transaction processing, and the GPS on your phone.

Cloud computing is the most important technology infrastructure most people never think about — a $905 billion market in 2026, growing to nearly $3 trillion by 2034. Over 94% of enterprises use cloud services. And the demand for cloud skills is so high that cloud engineers earn an average of $130,000 to $198,000 depending on role and experience, with 317,700 job openings posted every year.

Whether you want to understand the cloud for your current job, pivot into a cloud career, or simply stop feeling lost when someone mentions “AWS” in a meeting, this course gives you the foundation.

Cloud Computing in Plain English

At its core, cloud computing means using someone else’s computers over the internet instead of buying and maintaining your own. That’s it.

Instead of buying a server, setting it up in your office, paying for electricity, hiring someone to maintain it, and replacing it when it breaks — you rent computing power from a company that manages all of that for you. You pay for what you use, scale up when you need more, and scale down when you don’t.

Three things make cloud computing powerful:

Feature	What It Means	Why It Matters
On-demand	Get resources in minutes, not months	No waiting for hardware procurement
Scalable	Add or remove resources as needed	Handle traffic spikes without overbuying
Pay-as-you-go	Pay only for what you use	No wasted capacity sitting idle

Key Takeaways

Cloud computing powers virtually every digital service you use — email, messaging, streaming, AI assistants, and business software all run on cloud infrastructure
The cloud market is $905 billion in 2026, growing to $3 trillion by 2034, with 94% of enterprises already using cloud services
Cloud literacy is a business skill, not just a technical one — it affects budgets, hiring, strategy, security, and vendor decisions
Cloud careers are booming: $130K-198K salaries, 317,700 annual job openings, and 25-26% growth rate through 2034
At its simplest, cloud computing means using someone else’s computers over the internet — paying for what you use instead of buying and maintaining your own hardware
