DevOps Automation Engineer Beginner's Kit

To help aspiring IT professionals succeed in the automation field, "Learning Ansible" provides an in-depth primer that covers all the essential skills. The book is an excellent resource that will help you become an expert IT automation specialist and Ansible Developer.

Starting with an introduction to Ansible, the journey will show how crucial it is in today's IT settings. The first few chapters cover the essentials, diving into topics like configuration management, automation, integration, and orchestration. The authors make sure that readers can confidently troubleshoot issues by thoroughly examining network, performance, and security errors and providing advanced debugging techniques. Practical uses of Ansible in system administration, user and group management, and managing common and complex errors are explored throughout the book. Setup of network devices, software upgrade automation, and fixing recurring network problems are all covered in detail, along with example programs.

Next, we'll take a closer look at DevOps, with a focus on how Ansible has impacted CI/CD pipelines. The course teaches readers how to integrate Ansible with popular tools and cloud providers like AWS and Azure through and various tools such as Jenkins, Docker, and Kubernetes.

Additionally, integration is extended to databases such as MySQL and MongoDB, as well as monitoring tools such as Nagios and Prometheus. By incorporating practical exercises throughout, the book guarantees that its readers will grasp the concepts and be able to put them to use in actual situations.

"Mastering Shell for DevOps" is all about giving DevOps, cloud, and Linux folks the know-how to automate and make their workflows more efficient with shell scripting. The book uses real-world examples and simple instructions to show how to automate tasks and move away from manual work in a DevOps environment. We start with the basics of shell scripting, so you can learn to write scripts that get the job done. It then moves on to version control with Git and GitHub, showing the importance of collaboration and code management in this context. The book then jumps into infrastructure provisioning and configuration management, showing you how to automate the setup of servers and services using tools like AWS CLI, Docker, and Kubernetes. As your skills grow, you'll learn to set up monitoring and logging tools, automate incident detection and resolution, and manage network traffic and load balancing. The book also helps you learn how to automate security tasks, including user access management, vulnerability scanning, patching, and compliance checks. By the end of the book, you'll have a whole toolkit of shell scripts that will help you work more efficiently, reliably, and securely in your DevOps practices.

Key Features
