This book assumes that readers are already familiar with the basics of Amazon Web Services (AWS) and have some development background. It explains readers about Continuous Integration (CI) and Continuous Deployment (CD) and how they are achieved on AWS using Developer tools. Readers will also learn about different architectures and implement CI/CD on these architectures. Some of the troubleshooting and cost optimization tips are really helpful to the users while using different AWS services. Users can use free-tier cloud providers wherever possible; certain services might cost a small amount of money.

From a hardware point of view, you can work on any modern computer running for any operating system supported by AWS.
