Overview of this book

AWS certifications validate the technical skills and knowledge required for building secure and reliable applications on the AWS cloud. The AWS Certified Cloud Practitioner certification is for individuals who have the knowledge and skills necessary to demonstrate an understanding of the AWS Cloud, independent of specific technical roles addressed by other AWS certifications. An AWS Certified Cloud Practitioner is a recommended path to achieving specialty certification or an optional start toward Associate certification. This guide provides a solid introduction and the resources you need to prove your knowledge in the exam. It covers all topics, beginning with what the AWS cloud and its basic global infrastructure and architectural principles. Other chapters dive into the technical, exploring core characteristics of deploying and operating in the AWS Cloud Platform, as well as basic security and compliance aspects and the shared security model. The text identifies sources of documentation or technical assistance, such as white papers or support tickets. The authors discuss the AWS Cloud value proposition and define billing, account management, and pricing models.

Automation is a best practice when it comes to designing architectures in the cloud. Automation allows common tasks to be repeated faster than doing them manually. These tasks can be simple and routine, such as installing the latest security patches on an EC2 instance running Linux. Or they can be complex, perhaps creating an entirely new and pristine AWS environment containing dozens of EC2 instances running a multitier, database-backed web application behind an application load balancer.

Whatever the task, whether simple or complex, automation confers several benefits, including the following:

  • Rapid testing and experimentation
  • Reducing expenses
  • Minimizing human error
  • Rolling back changes safely and completely

Some have a misconception of automation as replacing a human with a machine. But the truth is that automation requires a tremendous amount of human intelligence and ongoing effort. Ultimately, automation is about increasing the capacity of the people doing the work...
