About AWS

Amazon's cloud story starts, somewhat unusually, with Amazon's own internal problems. In the early 2000s, the retail giant kept rebuilding the same infrastructure, computing power, storage, databases, over and over for each new internal project, and engineers eventually realized that infrastructure itself could be turned into a standardized, rentable product. That internal insight became Amazon Web Services, which quietly launched its first two services, S3 for storage and EC2 for computing power, both in 2006.

The idea seems obvious now: instead of buying and maintaining your own physical servers, you could rent computing power and storage by the hour from someone else's data centers, scaling up or down as needed. At the time, though, it was a genuinely new way of thinking about infrastructure, and AWS effectively invented the modern version of what we now just call cloud computing.

One of the most famous early AWS customers was Netflix, which spent years migrating its entire infrastructure off its own data centers and onto AWS, partly as a response to a major database corruption incident in 2008 that convinced the company it needed more resilient, distributed infrastructure than it could easily build and maintain itself.

Two decades after launch, AWS remains the largest cloud provider by market share, commanding roughly a third of the global cloud infrastructure market on its own, well ahead of its closest competitors. Its service catalog has grown to well over 200 individual offerings, covering everything from basic virtual machines to managed databases, machine learning platforms, and serverless computing through Lambda, which lets developers run code without managing any servers at all.

AWS's annual re:Invent conference has become one of the largest events in the entire tech industry, regularly used to announce dozens of new services and features in a single week, and AWS certifications have become genuinely valuable, well-recognized credentials on their own, separate from broader software development experience.

Because the AWS catalog is so vast, actually knowing your way around it, which service to reach for and why, has become a specialized and well-compensated skill in its own right, distinct from general programming ability.

Because so much of the internet quietly depends on AWS, its rare outages tend to become genuine news events rather than minor technical footnotes, with a single regional AWS disruption sometimes taking down large chunks of unrelated, seemingly unconnected websites and apps all at once, a vivid demonstration of just how much infrastructure runs on the platform behind the scenes.

The job market around AWS has grown into its own specialized field too. AWS-specific certifications, ranging from foundational to highly specialized professional-level exams, have become genuinely valuable credentials that many employers actively look for, sitting somewhere between a general computer science background and hands-on cloud infrastructure experience.

AWS's pricing model, paying only for what you actually use rather than for fixed hardware capacity sitting idle, was itself a significant part of the platform's early appeal to startups, letting a small team launch a new product without the large upfront capital expense that buying physical servers would have required just a few years earlier, fundamentally changing how much money a new company needed just to get started.
