Amazon Web Services (AWS) is a comprehensive and widely adopted cloud platform offering over 200 fully-featured services from data centers globally. Launched in 2006 by Amazon, AWS has grown to become the leading cloud services provider, supporting millions of customers ranging from startups to enterprises. With a wide range of services spanning computing, storage, databases, machine learning, networking, and beyond, AWS has transformed how businesses leverage cloud infrastructure and applications.

1. What is AWS?

Amazon Web Services (AWS) is a cloud computing platform provided by Amazon. It offers on-demand cloud services that allow businesses to run their applications, store data, and scale their infrastructure without owning physical hardware. AWS provides a flexible, secure, and scalable infrastructure for running applications of any size, from small websites to large-scale enterprise solutions.

AWS operates on a pay-as-you-go model, meaning businesses only pay for the resources they use, which helps optimize costs and increase flexibility. This model has helped businesses transition from traditional on-premises IT systems to the cloud, where they can access resources in real time and scale dynamically according to demand.
