The DevOps Engineer's Career Guide

Who are DevOps Engineers, What are their daily activities like, What were they doing before getting into DevOps, Is my current experience in line with the DevOps role?
Well, in the last four months, I have been involved in the recruitment process of various DevOps related jobs in my current project. I have come across multiple Entry Level and Mid-Level career professionals inquisitive about expectations of the role and how their earlier experience would contribute to the DevOps role. 
Also, I have received several emails from readers asking how to switch from their existing roles (development, sysadmin, etc.). Based on the interactions, I have included "DevOps Engineer" related queries in the below categories and in this book, I will give you complete information about the position, career path and skill set required.
The main queries were the following:

• Why DevOps?
• What are the job duties and day-to-day activities of a DevOps Engineer?
• What did DevOps engineers do before DevOps?
• What technical and soft skills are required to be an expert-level DevOps Engineer?
• What are some standard tools a DevOps engineer uses?
• What are other similar roles from where one can make the transition to the DevOps world?
• What are the Certifications/Courses one can do to become a DevOps Engineer?
• How can I get DevOps interviews with top companies?
• What are the average Salary, companies to work for, and designations/roles?
• How is the career path of a "DevOps Engineer"? How is the career advancement of a DevOps engineer?

The book covers most of this information. Over the course of the book, you will gather information on what DevOps is, and how you can use it to improve your processes. You will also identify the different roles that are linked to DevOps. If you are keen on becoming a DevOps engineer, the last few chapters include information on what skillsyou need to develop and what path you need to choose. Also, the last chapter contains sample interview questions, which are the most common ones asked during a DevOps interview.
Overall, this book is aimed at professionals looking for a DevOps role overview in a limited timeframe. 
If you have to connect the dots regarding your existing experience, credentials and its fitment/relationship with the DevOps role, it would provide you much-needed clarity. It also talks about other similar and related roles and its relationship with the DevOps role. Also, if you are part of the Project Management Team or Business Development Team or recruitment team (HR) this book will provide you required information about the DevOps role.
Continuous Delivery is here to stay and evolve. The nomenclature would change; new buzzwords would come and go. So, if you are into this space, adapt to it and make it your growth engine.
Cheers!
