You've probably seen that weird URL string starting with "s3.amazonaws" while trying to download a PDF or loading a high-res image on a random blog. It looks like tech gibberish. Most people just ignore it, but if you're asking amazonaws what is it, you've stumbled upon the literal skeleton of the modern internet.
Think about it this way.
Back in the early 2000s, if you wanted to start a website, you had to buy a physical server, find a room with a loud air conditioner to put it in, and pray the power didn't go out. Amazon, being a massive bookstore that was rapidly turning into an "everything store," realized they were getting really good at managing this nightmare at scale. They had all this computing power sitting around during non-peak months.
So, they decided to rent it out.
Today, Amazon Web Services (AWS) is a behemoth. It's not just "storage." It is a massive, global collection of data centers that provide the muscle for companies like Netflix, Airbnb, and even the CIA. Honestly, if AWS went down for a full day, half the apps on your phone would just be expensive bricks.
The "Everything" Box: Breaking Down the Services
People get confused because AWS isn't one thing. It’s actually over 200 different services. Imagine a giant LEGO set where every brick does something different—one brick is a hard drive, another is a super-fast processor, and another is a smart robot that can recognize faces in photos.
The core of the whole thing is usually three big pillars.
First, you have Amazon EC2 (Elastic Compute Cloud). This is basically a virtual computer. You rent a slice of a massive server in, say, Northern Virginia, and you can run whatever software you want on it. The "elastic" part is key. If your website suddenly gets a million hits because a celebrity tweeted about it, EC2 can automatically spin up ten more "computers" to handle the load. When the hype dies down, it turns them off so you stop paying for them. It’s brilliant.
Then there is Amazon S3 (Simple Storage Service). This is where that "amazonaws" link usually comes from. It’s a giant digital warehouse for files. Netflix uses it to store petabytes of video files. It's incredibly durable—Amazon famously claims "eleven nines" of durability ($99.999999999%$), meaning if you store 10,000 files there, you might lose one every 10 million years.
Finally, you've got Amazon RDS for databases. Instead of you having to learn how to install and patch a database, Amazon does the boring maintenance stuff for you. You just use it.
Why Does Every Developer Use It?
Honestly, it’s about the money and the speed.
Before AWS, a startup needed $50,000 in hardware just to see if their idea worked. Now? You can start for $5 a month. You pay for what you use. It's like a utility bill—you don't own the power plant; you just pay for the electricity that comes out of the wall.
Andy Jassy, who is now the CEO of Amazon but was the original mastermind behind AWS, pushed the idea that "infrastructure" shouldn't be a bottleneck. He wanted developers to be able to build things in minutes, not months.
But it's not all sunshine.
The complexity is staggering. Trying to navigate the AWS Management Console is like looking at the cockpit of a 747. If you click the wrong button or leave a high-powered instance running by mistake, you can wake up to a $10,000 bill. It happens more often than you'd think. This has created a whole industry of "AWS Cost Optimization" experts whose only job is to tell companies they're overspending.
The Competition and the Controversy
AWS isn't the only player anymore. Microsoft has Azure, and Google has Google Cloud Platform (GCP).
Azure is huge with big banks and corporations because they already use Windows and Office. GCP is the go-to for heavy data crunching and AI. Yet, AWS stays on top because they were first. They have the most features. They have the most "regions"—physical locations where their servers live—meaning your website can load just as fast in Tokyo as it does in London.

There's a weird irony here, though. Amazon’s retail side is a competitor to companies like Walmart or Target. For a long time, these retailers refused to use AWS because they didn't want to give money to their biggest rival. They didn't want their data sitting on Amazon's "property." Eventually, the tech was so much better than anything else that many swallowed their pride and signed up anyway.
Is It Safe?
When people ask amazonaws what is it, they usually follow up with: "Is my data safe there?"
Technically, yes. Amazon spends billions on physical security. Their data centers are unmarked, guarded by biometric scanners, and designed to survive disasters.
However, the "leaks" you hear about in the news—like when millions of voter records or credit card numbers are exposed—are almost never Amazon's fault. It’s usually a "misconfigured S3 bucket." This is tech-speak for "the person who set it up forgot to turn on the password." It’s like Amazon built a world-class vault, but the customer left the front door wide open.
The AI Shift
Right now, AWS is pivoting hard toward Generative AI. They launched something called Amazon Bedrock, which lets businesses build their own versions of ChatGPT without having to build the underlying models themselves.
They are also making their own chips. While everyone is fighting over Nvidia chips, Amazon is building Trainium and Inferentia chips specifically designed to run massive AI workloads cheaper than the standard hardware. This is a massive play to keep companies from switching to Google or Microsoft as the AI wars heat up.
What This Means For You
If you aren't a developer, you won't "use" AWS directly. But you are using it every second.
- Watching a movie on Prime Video? AWS.
- Checking your Slack messages at work? AWS.
- Playing Fortnite? Yep, AWS.
It has turned computing into a commodity. It’s no longer a physical thing you own; it’s a service you stream.
Actionable Steps for Exploring AWS
If you're curious about how this works or want to start a project, here is how you actually get your feet wet without losing your shirt.
- Sign up for the Free Tier. Amazon offers a "Free Tier" for new accounts. It gives you 12 months of limited access to things like EC2 and S3. It’s the best way to learn.
- Set a Billing Alarm immediately. This is the most important step. Before you do anything, go to the billing dashboard and set an alarm to email you if your charges exceed $1. Seriously.
- Check out AWS Cloud Practitioner Essentials. It’s a free, 6-hour digital course provided by Amazon. It explains the "what is it" in a way that doesn't require a computer science degree.
- Use S3 for a basic static website. If you have a simple HTML resume or a portfolio, try hosting it on S3. It will cost you pennies a month and teach you exactly how those "amazonaws" links are created.
- Look into "Serverless" (AWS Lambda). If you really want to see the future, look at Lambda. It allows you to run code without even "renting" a server. You just upload the code, and it runs only when needed. You pay by the millisecond.
AWS is a sprawling, messy, brilliant ecosystem. It’s the reason a two-person startup can compete with a Fortune 500 company. Understanding it isn't just for "tech people" anymore; it's about understanding how the economy actually functions in the 21st century.
