The History of AWS: How Amazon Built the Cloud

Most people use AWS every day without knowing where it came from. Here's the simple story of how Amazon Web Services started and grew into the world's biggest cloud platform.

In the early 2000s, Amazon was just an online bookstore trying to grow into a bigger e-commerce company. As they scaled, their engineering teams kept running into the same issue: every team was rebuilding the same basic infrastructure — storage, databases, servers — again and again for each new project.

By the summer of 2003, Andy Jassy had taken charge of building a solution, and his team mapped out a vision for what they called an "Internet OS" — a set of core building blocks that any application could use instead of starting from scratch.

In late 2003, engineers Chris Pinkham and Benjamin Black wrote an internal paper describing standardized, fully automated computing infrastructure — and near the end, they suggested Amazon could even sell this as a service to other companies. That idea became EC2.

Amazon Simple Storage Service (S3) launched on March 14, 2006, becoming AWS's first major public product, with EC2 following a few months later in August 2006. Together, these two services let any developer — even, as AWS itself puts it, "a kid in a college dorm room" — rent the same computing power used by huge companies.

Once S3 and EC2 proved the model worked, AWS kept adding services year after year: databases, networking, machine learning, and more. By 2015, AWS had become Amazon's most profitable business, and it's remained the leading cloud provider ever since — powering everything from small startups to Fortune 500 companies.

As students building on AWS today — through PartyRock, EC2, or any of the 200+ services now available — it's worth remembering this all started with a simple idea: make powerful infrastructure available to anyone, not just big companies. That's the same spirit I try to bring to our AWS Student Builder Group at APCOE&R.
