Introduction
Have you struggled with setting up your server infrastructure? Imagine if it worked like a utility—similar to an electric grid—where you only pay for what you use. That’s the power of cloud computing!
What is Cloud Computing?
The first time I heard the term cloud computing, I thought it was just an infinite storage space. Back then, I used Google Drive and Google Photos for backups.
Let’s dive into the technical definition:
Cloud computing is the on-demand delivery of IT resources needed to develop and run software applications. It follows a pay-as-you-go pricing model.
What is On-Demand Delivery?
It’s like ordering food on Swiggy:
Need food? Click a button, and it’s delivered to you.
Need IT resources? Click a button, and they’re instantly available.
What is Pay-as-You-Go Pricing?
You only pay for what you use. When you don’t need the resources anymore, you stop paying—no long-term commitment.
What are IT Resources?
These include computing power, storage, networking, and databases—the essentials for running applications.
Think of AWS as a rental service. Just like renting an apartment gives you access to amenities (elevator, parking, security), AWS provides the infrastructure to build software without purchasing expensive hardware.
If you run an on-premises data center, you lack this flexibility—one major difference between cloud computing and traditional IT setups.
Key Concepts of Cloud Computing
1. Pay Only for What You Use
Let’s say David owns a coffee shop, Kapi Tagista. He employs a cashier and a barista to serve 50 customers daily.
One day, after launching a new Beetroot Blast flavor, 100 customers show up. With just two employees, service slows down.
On-Premises Approach:
David would need to hire extra employees in advance and continue paying them even when demand drops.
Cloud Approach:
David could temporarily hire extra baristas (servers) only for peak days and release them when demand normalizes.
💡 In simple terms:
Need more servers? ✅ Rent them instantly.
No longer need them? ❌ Stop paying.
This scalability is what makes cloud computing powerful.
2. Eliminating IT Heavy Lifting
Building a software application involves time-consuming, repetitive infrastructure tasks—like a coffee shop needing staff to make coffee and take orders.
AWS handles the “heavy lifting” so developers can focus on what truly matters: building great applications.
Jeff Bezos’ Analogy (2003 Y Combinator Speech)
AWS is like an electric power generator. In the past, breweries had to generate their own electricity because there was no power grid. But making electricity didn’t improve the beer!
Similarly, AWS allows businesses to focus on their "beer" (software) instead of spending resources on infrastructure.
👉 AWS is like a LEGO set—you can build anything with its services.
3. Cloud-Based Deployment
Companies can: ✅ Shift software from on-premises data centers to the cloud. ✅ Design and build applications directly in the cloud.
Imagine running an online store. Instead of buying and managing physical servers, you run everything on the cloud—scalable, flexible, and hassle-free.
Amazon Elastic Compute Cloud (EC2)
To build software, you need computing power. AWS provides virtual servers called EC2 instances to host applications.
Why Use EC2 Instead of On-Premises Servers?
✔ Flexibility – Instantly scale up or down as needed.
✔ Cost-Effective – No upfront investment in hardware.
✔ Quick Deployment – Launch servers in milliseconds.
Traditional On-Premises Setup vs. EC2
Buying physical servers requires time, space, and maintenance.
With EC2, you rent servers, avoiding infrastructure headaches.
Let's say you want to set up on-premises servers for your business; the process starts with choosing the right server type based on your needs and buying the required number, which can be costly. After purchasing, it takes days for the vendor to deliver the servers. Once they arrive, you'll need to take them to your data center, install, rack, and wire them, ensuring they're secure and powered. Finally, they're ready for use, and you can host your applications on them.
Why EC2 is Better
Buying servers and storing them requires more space and time as workloads grow.
With EC2, you can instantly add or remove servers and pay only for what you use.
You eliminate extra costs like wiring, server delivery, and real estate, making it cost-effective.
💡 A mouse click takes just 85 milliseconds—that’s how fast you can launch an EC2 instance!

Conclusion
Cloud computing is more than just technology—it’s freedom. The freedom to build without limits, scale without fear, and pay only for what you use. Instead of spending weeks setting up physical servers, you can launch and scale in seconds with Amazon EC2.
Why Should You Care?
✅ Flexibility – Need more power? Get it instantly. Need less? Scale down effortlessly.
✅ Cost-Effectiveness – No more wasting money on hardware you don’t use.
✅ Speed – From idea to execution in milliseconds, not months.
What If You Could Skip the Headaches?
Imagine working on your dream project, but instead of worrying about servers, wiring, and maintenance, you focus on what truly matters—your idea.
This is why cloud computing exists. It eliminates the struggle so you can innovate, grow, and build without barriers.

Why I Share This
Simon Squibb believes that the best way to share knowledge is to make it simple and accessible. And that’s exactly what I do—I break down complex tech into something easy and exciting.
Tech should inspire you, not intimidate you.
Imagine a world without the cloud—every startup would need huge investments just to get started. AWS changed that game. The cloud lets anyone with an idea build something incredible without worrying about infrastructure.
I share knowledge this way because I want you to feel that excitement too.
