DevOps: Hype or Hope
•
8 likes•936 views
DevOps aims to break down silos between development and operations teams to reduce risks and speed up the software development process. It promotes continuous integration, delivery, testing and monitoring to catch issues early. While tools can help, DevOps is primarily a cultural shift where teams collaborate throughout the development lifecycle. Benefits include faster time to market, improved quality, better productivity and visibility into issues. Challenges involve changing mindsets and incentivizing collaboration between different roles.
