How AWS transformed IT by making cloud computing accessible to everyone

Key takeaways Before cloud computing, switching IT providers was an expensive, multi-year undertaking. AWS has continuously invested in delivering cost-effective IT tools, making it easier for customers to work across multiple IT environments.

AI services are now available across a wide array of IT tools, spurring innovation and giving customers unprecedented freedom to choose. In March 2006, AWS launched with a simple but radical idea: give anyone with a credit card and an internet connection access to enterprise-grade information technology on demand, with efficient, pay-as-you-go pricing.

No massive upfront investment in hardware and software required. Just technology, on demand, for everyone.

The radical network redesign that led AWS to forge a more resilient cloud How a Slack shout-out, a dusted-off academic theory, and a spaghetti monster led an AWS team to crack an elusive code—and deliver greater reliability and performance for customers.

20 years on, we remain pioneers with that founding idea, that technology should be easy to access and in the hands of the customer, still driving everything we do.

What cloud computing changed for customers Before cloud computing, companies made huge upfront investments in hardware and security, rewrote software to fit proprietary systems, and often found themselves locked into a single vendor for years. Cloud computing fundamentally changed that.

Startups that would've needed millions in upfront capital could now launch with a credit card. Businesses could scale up during peak demand and scale down when things were quiet, paying only for what they used.

Companies could experiment with new products without betting the business on expensive infrastructure, enter new markets quickly, and pivot when needed. The impact went beyond individual businesses. Cloud computing put powerful technology within the reach of everyone.

A developer in Bangalore could build and deploy applications using the same tools as a team in Silicon Valley. A researcher in São Paulo could access powerful computing resources for data analysis without needing to wait for time in a university computer lab. Small businesses could compete with Fortune 500 companies on technology capabilities.

Listening to customers’ needs As customers began building on AWS, they told us what they needed: a diverse array of services, enterprise grade security and performance, and the ability to work across multiple IT environments. We listened. We use open standards, publish our APIs, and make our software development kits available under open source licenses.

These were deliberate choices driven by what customers told us they needed: freedom in how they use our services and the ability to move quickly and adapt as their needs change. AWS is committed to customer choice and flexibility, accelerated by AI New tools build upon the AWS tradition of giving customers more freedom in IT services. Take containers.

We embraced Kubernetes—an open source tool originally developed by Google—because our customers told us they wanted that flexibility. That's the pattern we've followed for 20 years: listening to what customers need and building solutions that give them more freedom, not less.

Making it easier to choose Over the past 20 years, we've continuously invested in making it easier for customers to work across multiple IT environments, if they need to. We've eliminated data transfer fees globally for customers who want to move their data to another environment.

We’ve invested in migration tools that work regardless of where a customer is moving to or from. And we’ve published detailed documentation on data formats and structures. We continue to support open source communities including Linux, Kubernetes, PostgreSQL, Apache, and others.

For example, Valkey, is an open source, high-performance, in-memory datastore for caching and messaging that AWS helped to launch, and is now backed by the Linux Foundation. We've also built tools and services specifically designed to help customers migrate workloads to AWS, from AWS, or between different environments entirely.

These changes are about giving customers the freedom to build on their own terms while maintaining the highest levels of data security and privacy. AI expands choice We've launched more than 240 services and reduced our prices at least 161 times.

But what matters most isn't just the number, quality, and price performance of services, it's how each innovation creates new possibilities for customers. OpenAI models GPT-5. 5 and GPT-5.

4—and Codex—now on Amazon Bedrock For the first time, the most advanced OpenAI models are available on Amazon Bedrock, with pricing that matches OpenAI first-party rates and no additional fees. Nowhere is this clearer than in AI, where we've developed tools that expand access and choice.

Amazon Bedrock gives customers access to more than 100 foundation models from dozens of companies—not jus
