AWS is a cloud computing platform offered by Amazon. It offers a large set of services that can be utilized in various forms. AWS caters for different services, including infrastructure, networking, storage, databases, security, and many more. These different services can be used in the application life cycle. Also, AWS offers a pay-as-you-go pricing model, which means that the user will only pay for services being used, so the user doesn't have to pay any upfront fees to acquire hardware resources.
AWS offers a web service interface for all services. We can also integrate AWS services via web services with various software to make our application management easier. AWS offers multiple regions to create AWS services.
The user has the choice to select the regions based on the application usage so that latency is low. Each region has multiple Availability Zones (AZ), which means you have an option to select Availability Zones where the application will reside, to avoid failure when one availability zone is down but another may be up.
