What is DevOps?
Kelly Shortridge and Nicole Forsgren, PhD convinced me of its importance during their Controlled Chaos: The Inevitable Marriage of DevOps & Security talk at Black Hat. Dino Dai Zovi emphasized this in his Black Hat keynote Every Security Team is a Software Team Now.
- Inspired by "Lean Manufacturing" or the "Toyota Manufacturing Method."
- Grady Booch used the terminology Continuous Integration in the 1991 "Booch Method".

- Manifesto for Agile Software Development was published in 2001. Written by representatives of extreme programming, scrum, etc.
- Andrew Schafer and Patrick Debois met in 2008 through the Agile Conference in Toronto. They created an Agile Systems Administrator group on Google.
- John Allspaw and Paul Hammond in 2009 gave a talk 10+ Deploys a Day: Dev and Ops Cooperation at Flickr. Software Craftsmanship Manifesto was published in 2009. Patrick Debois started DevOpsDays conference in 2009

- Nicole Forsgren, PhD, Jez Humble, and Gene Kim publish Accelerate: The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations.
Bridges the gap between development and IT operations that was created by lean development methodologies that rapidly deliver software.
Automation and faster releases from CI/CD contribute to DevOps. CI/CD automates the integration, delivery, and deployment stages.
Continuous deployment is a superset of continuous delivery that also automates the deployment process.
Shifting security left through software composition, SAST, DAST and IAST. Security testing is started earlier in the development lifecycle.
Site-reliability engineering contributes to continuously deploying new features while maintaining high-quality end-user experience.
