The Amazon Web Services (AWS) is a collection of cloud-based Infrastructure as a Service (IaaS) services that make up the backbone of internet services in today's digital age. It is designed to make it easier for developers to build, deploy, and run applications on websites, mobile apps, and physical devices. By providing these services through an "internet scale" technology platform, AWS allows users to avoid having to worry about scaling issues or managing an in-house infrastructure. AWS developer certification can focus on building their applications with the same tools and skills they use every day, while AWS handles scaling and maintenance.
