Effective DevOps with AWS - Second Edition

Book Description

Scale and maintain outstanding performance in your AWS-based infrastructure using DevOps principles

Key Features

  • Implement continuous integration and continuous deployment pipelines on AWS
  • Gain insight from an expert who has worked with Silicon Valley's most high-profile companies
  • Implement DevOps principles to take full advantage of the AWS stack and services

Book Description

The DevOps movement has transformed the way modern tech companies work. Amazon Web Services (AWS), which has been at the forefront of the cloud computing revolution, has also been a key contributor to the DevOps movement, creating a huge range of managed services that help you implement DevOps principles.

Effective DevOps with AWS, Second Edition will help you to understand how the most successful tech start-ups launch and scale their services on AWS, and will teach you how you can do the same. This book explains how to treat infrastructure as code, meaning you can bring resources online and offline as easily as you control your software. You will also build a continuous integration and continuous deployment pipeline to keep your app up to date. Once you have gotten to grips will all this, we'll move on to how to scale your applications to offer maximum performance to users even when traffic spikes, by using the latest technologies, such as containers. In addition to this, you'll get insights into monitoring and alerting, so you can make sure your users have the best experience when using your service. In the concluding chapters, we'll cover inbuilt AWS tools such as CodeDeploy and CloudFormation, which are used by many AWS administrators to perform DevOps. By the end of this book, you'll have learned how to ensure the security of your platform and data, using the latest and most prominent AWS tools.

What you will learn

  • Implement automatic AWS instance provisioning using CloudFormation
  • Deploy your application on a provisioned infrastructure with Ansible
  • Manage infrastructure using Terraform
  • Build and deploy a CI/CD pipeline with Automated Testing on AWS
  • Understand the container journey for a CI/CD pipeline using AWS ECS
  • Monitor and secure your AWS environment
