Amazon Web Services

World's Most Comprehensive Cloud Platform

Amazon Web Services (AWS) is the world's most comprehensive and broadly adopted cloud platform, offering over 200 fully featured services from data centers globally. Launched in 2006, AWS provides a reliable, scalable, and inexpensive cloud computing infrastructure that powers hundreds of thousands of businesses in 190 countries. From startups to Fortune 500 companies, organizations use AWS to lower costs, become more agile, and innovate faster with services spanning compute, storage, databases, machine learning, analytics, IoT, and more.

What is AWS?

Amazon Web Services is a comprehensive, evolving cloud computing platform provided by Amazon. It offers a mixture of infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) offerings. AWS was one of the first companies to introduce a pay-as-you-go cloud computing model that scales to provide users with compute, storage, or throughput as needed.

AWS operates from geographic regions around the world, each containing multiple isolated locations known as Availability Zones. This infrastructure provides redundancy and the ability to remain resilient in the face of most failure scenarios. AWS enables businesses to access servers, storage, databases, and a broad set of application services over the internet on a pay-for-what-you-use basis.
