Cloud computing is driving the IT industry to restructure the application workflow. It offers low-cost services for IT resources over the internet and a pay-as-you-go pricing model. Under cloud computing, IT resources can be utilized on demand. So, you don't need to pay for unused resources or any upfront fees to provision any hardware in advance.
Amazon Web Services (AWS) is a leading cloud services provider. AWS offers different services in various graphical regions, which can be chosen by customers based on their requirements. With AWS, we can create high availability and fault tolerant applications with minimal configurations. AWS reduces the stress of managing on-premises physical servers and allows us to focus on application layers.
The following topics will be covered in this chapter:
- Introduction to AWS
- Sign-up process
- Installation of the AWS CLI
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 aÂ pay-as-you-go pricing model,Â 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.
