Ans: DevOps are one of the highly paid job as per Business Insider, Glassdoor and PayScale
survey.

Q6. How will this course help me learn DevOps?
Ans: Our focus is on training you on Real Time use cases and not just one by one introduction to
tools. For this very reason we have created Vprofile application. You will learn all the latest and
greatest DevOps tool in the market and most importantly integrate them together to setup
Orchestration of Continuous Delivery. Yes we said orchestration and not simple automation scripts.

Q7. What is Vprofile Application?

Ans: Vprofile is a java based Web Application written by our expert Developers. Its a social
networking website like Facebook.
In Real time you will have multiple services/servers working together to create a web service like
Facebook or Twitter or Amazon or Flipkart. To deliver features to the website, developers will code
new features and Operations team will deploy them into production servers. By using DevOps
principles and Tools we can deliver features more rapidly to production systems.
We have taken the same approach and will train you in the similar manner.
