Question 2:
What is the need for DevOps?
Answer:
Instead of releasing big sets of features, companies are trying to see if small features can be transported to their customers through a series of release trains. This has many advantages like quick feedback from customers, better quality of software etc., which in turn leads to high customer satisfaction. To achieve this, companies are required to:
Increase deployment frequency
Lower failure rate of new releases
Shortened lead time between fixes
Faster mean time to recovery in the event of new release crashing
DevOps fulfills all these requirements and helps in achieving seamless software delivery. You can give examples of companies like Etsy, Google and Amazon which have adopted DevOps to achieve levels of performance that were unthinkable even five years ago. They are doing tens, hundreds or even thousands of code deployments per day while delivering world class stability, reliability and security.
