This book is for you if you are a developer, DevOps engineer, or you work in a team which wants to build and use AWS for software infrastructure. Basic computer science knowledge is required to get the most out of this book.

Chapter 1, The Cloud and DevOps Revolution, this chapter will set the foundation to anyone about the need of DevOps and Cloud Journey. An in depth understanding of DevOps culture, DevOps Terminology and AWS ecosystem will be gained to start and prepare the roadmap for future chapters.

Chapter 2, Deploying Your First Web Application, this chapter will demonstrate AWS infrastructure provisioning in simplest form with some of the best AWS authentication practices. We will create a simple web application and understand how to host the application on AWS in the easiest form and finally will terminate the instance. This whole process will be implemented using AWS cli utility and will be automated in further chapter to understand how manual tasks can be automated using different available AWS and other famous services and products.

Chapter 3, Treating Your Infrastructure as Code, this chapter will focus on Automating Provisioning using AWS native utility CloudFormation and the techniques used to create CloudFormation templates. Then we will introduce a Configuration Management system to automate application deployments with Ansible.

Chapter 4, Infrastructure as Code with Terraform, this chapter will focus on understanding the fundamentals of Terraform. We will provision our first AWS instance using Terraform templates and then extend the power of Terraform to deploy the application using another Terraform Template. Finally we will understand AWS provisioning using Terraform by integrate it with Ansible automation for application deployments.

Chapter 5, Adding Continuous Integration and Continuous Deployment, this chapter will focus on building CI/CD pipelines using AWS DevOps services with Automated Testing Framework. We will prepare a technology framework using multiple tools like Version Control, Continuous Integration, Automated Testing tools, AWS native DevOps tools and Infrastructure Automation tools to understand how fail fast and fail often lead to an robust production environment.

Chapter 6, Scaling Your Infrastructure, this chapter will introduce other useful cost effective AWS services to build scalable AWS infrastructure with performance oriented vision. AWS services like Elastic Cache, CloudFront, SQS, Kinesis and so on will be used to build our application Framework.

Chapter 7, Running Containers in AWS,  this chapter will introduce one of the most niche technologies in the market Docker. We will get started with the understanding of container using Docker with all of the essential concepts. Here we will build AWS container environment with ECS and build a complete framework of ECS for our application. At last we will build a complete CI/CD pipeline to deploy AWS ECS services using AWS DevOps tool set.

Chapter 8, Hardening the Security of Your AWS Environment, this chapter will focus on identifying and securing your AWS environment using AWS auditing services, AWS IAM services for managing and providing limited access as per roles, strengthening AWS VPC model and finally protecting against ransomware and other vulnerabilities.

Chapter 9, Monitoring and Alerting, this chapter will focus on building a monitoring framework for your AWS environment using AWS CloudWatch service. We will use some of the famous dashboard tools for visualization of logs. Finally a notification framework will be created using AWS SNS services to notify the users about the health of your AWS environment to take corrective actions.
