AWS stands for Amazon Web Services. It is a cloud computing platform provided by Amazon that offers a wide range of services for computing, storage, networking, databases, analytics, machine learning, and many other tools and services that can be used to build and deploy applications in the cloud. AWS provides an infrastructure for businesses to run their applications, store and manage their data, and access computing resources on-demand. With AWS, businesses can avoid the need to invest in expensive hardware and can instead use a pay-as-you-go model to scale their resources up or down based on their needs.
