Q: Tell me what DevOps is and what it can do for me
A: DevOps is a movement that has come about because of the conflict between IT Development and IT Operation teams, which are traditionally quite siloed. What has happened in IT is that: "software is eating the world"; what this means is that applications and IT have become more critically strategic to companies today; everyone has to take advantage of the internet otherwise their businesses won’t survive. This has given us a situation where businesses are putting a lot of pressure on IT Development to produce a lot of innovation which means there is a lot of change and, particularly in traditional enterprises, what we have are infrastructures that have evolved over several decades, that are very sophisticated and actually quite fragile. We have IT Operations teams that are very keen to keep the systems up and running (as they are often rewarded on up time). And this is where the conflict arises as you’ve got the development team who are trying to push through change whilst the operations team are trying to keep systems stable, so they don’t want change - change is risky.
