How Amazon EC2 grew from a notion into a foundational element of cloud computing

Published August 28, 2021

Fifteen years ago this week on August 25, 2006, AWS turned on the very first beta instance of EC2, its cloud-based virtual computers. Today cloud computing, and more specifically infrastructure as a service, is a staple of how businesses use computing, but at that moment it wasn’t a well known or widely understood concept.

The EC in EC2 stands for Elastic Compute, and that name was chosen deliberately. The idea was to provide as much compute power as you needed to do a job, then shut it down when you no longer needed it — making it flexible like an elastic band. The launch of EC2 in beta was preceded by the beta release of S3 storage six months earlier, and both services marked the starting point in AWS’ cloud infrastructure journey.

You really can’t overstate what Amazon was able to accomplish with these moves. It was able to anticipate an entirely different way of computing and create a market and a substantial side business in the process. It took vision to recognize what was coming and the courage to forge ahead and invest the resources necessary to make it happen, something that every business could learn from.

The AWS origin story is complex, but it was about bringing the IT power of the Amazon business to others. Amazon at the time was not the business it is today, but it was still rather substantial and still had to deal with massive fluctuations in traffic such as Black Friday when its website would be flooded with traffic for a short but sustained period of time. While the goal of an e-commerce site, and indeed every business, is attracting as many customers as possible, keeping the site up under such stress takes some doing and Amazon was learning how to do that well.

Those lessons and a desire to bring the company’s internal development processes under control would eventually lead to what we know today as Amazon Web Services, and that side business would help fuel a whole generation of startups. We spoke to Dave Brown, who is VP of EC2 today, and who helped build the first versions of the tech, to find out how this technological shift went down.

Sometimes you get a great notion

The genesis of the idea behind AWS started in the 2000 timeframe when the company began looking at creating a set of services to simplify how they produced software internally. Eventually, they developed a set of foundational services — compute, storage and database — that every developer could tap into.

But the idea of selling that set of services really began to take shape at an executive offsite at Jeff Bezos’ house in 2003. A 2016 TechCrunch article on the origins AWS described how that started to come together:

As the team worked, Jassy recalled, they realized they had also become quite good at running infrastructure services like compute, storage and database (due to those previously articulated internal requirements). What’s more, they had become highly skilled at running reliable, scalable, cost-effective data centers out of need. As a low-margin business like Amazon, they had to be as lean and efficient as possible.

They realized that those skills and abilities could translate into a side business that would eventually become AWS. It would take a while to put these initial ideas into action, but by December 2004, they had opened an engineering office in South Africa to begin building what would become EC2. As Brown explains it, the company was looking to expand outside of Seattle at the time, and Chris Pinkham, who was director in those days, hailed from South Africa and wanted to return home.
