DAY 1 ! Fundamentals of DevOps

Q1. What is DevOps? - DevOps is presented as a culture that improves an organization's ability to deliver applications. Its ultimate goal is to enhance the delivery process.

Ans: • DevOps as a Culture and Practice (Not Just a Tool):

◦ DevOps is fundamentally defined as a "practice or a culture that you are adopting in your organization". It is a "way of working" rather than a specific tool or a single defined process.

◦ The "end goal of DevOps" is to "increase your organization's ability to deliver applications". This means making the delivery process "quicker".

◦ "Delivery is the key factor" for any organization, whether it's Amazon.com, Flipkart.com, or PUBG. The objective is to "fasten up the application delivery process.

Q5. What is the Software Development Life Cycle?

Ans:- • Integration into the SDLC/DevOps Lifecycle:

◦ The primary goal of DevOps is to "fasten up the application delivery process" and "improve the process of delivery". This involves reducing the time it takes to deliver applications from days or weeks to hours or a day or two.

◦ The sources state that pre-DevOps, the entire delivery process was "manual effort," "slow," and involved "different teams," leading to lengthy delivery times (e.g., 10 days, one month). DevOps emerged "to automate this entire process".
