What is Amazon Web Services?
Amazon Web Services (AWS) is a comprehensive and widely adopted cloud platform offered by Amazon. Launched in 2006, AWS provides on-demand access to a wide variety of computing services such as servers, storage, databases, networking, analytics, machine learning, and more — all delivered over the internet, or “the cloud.”
AWS operates from data centers located around the world, ensuring high availability, scalability, and security. It offers businesses the flexibility to build and deploy applications without the upfront cost and complexity of owning and maintaining physical servers. Instead, companies can rent resources on a pay-as-you-go basis, paying only for what they use.
With millions of active users across industries like finance, healthcare, education, entertainment, and government, AWS has become a dominant force in the cloud computing market. Its services are designed to be highly reliable, secure, and scalable, making it the go-to choice for businesses ranging from small startups to Fortune 500 companies.
In short, when someone asks "what is AWS", the answer is simple: it’s a powerful, flexible, and secure cloud platform that empowers businesses to innovate and grow.
