To be able to answer "What is AWS?", you must first understand that it's a cloud provider. Among other features, cloud providers grant more storage flexibility and enhanced security measures. They also contain features you'd find at a local data center, like bolstered security, higher computing capacity, and database construction. Depending on your location, you can get other features like content caching.
One of the advantages of AWSis that you get all 160 cloud services on a pay-as-you-go basis. This means that you pay only for the services you use. And it works on a relative scale. That means the less you use it, the less you pay. And the more you use it, the less you pay per unit. (i.e., The price of each unit goes down with each new purchase.)
That's not all. Other advantages of AWS relate to the applications associated with it.
