AWS is focused on enterprise clients that can afford to have dedicated DevOps engineers. AWS Wizard makes it easy to use all infrastructure from AWS without special skills. It automates all the error-prone deployment and configuration tasks and sets everything up the way developers expect out of the box.
This means that you can get started with AWS microservices easily, and focus on solving important business problems instead of dealing with AWS deployment workflows.
Cloudfront/Terraform/Ansible helps DevOps to build complex solutions. AWS Wizard allows you to go without DevOps using simple solutions.
