What is AWS Service?

An AWS Service is a cloud-based service provided by Amazon Web Services (AWS) that helps you perform different tasks over the internet. Instead of buying and managing your own servers, storage, databases, or other hardware, you can use these services as needed.

AWS provides many different services for different purposes. For example, you can use Amazon EC2 to run applications, Amazon S3 to store files and data, and Amazon RDS to manage databases. These services make it easier to build, run, and manage applications without maintaining physical infrastructure yourself.
