DevOps demystified discusses DevOps culture and practices. DevOps involves development and operations engineers collaborating throughout the software lifecycle from design to production support. It is not a role, team, tool, or single strategy. Effective DevOps requires people, processes, and technologies working together and prioritizing communication, collaboration, automation, and reliability. Key aspects include reducing lead times, improving release frequency, incorporating feedback loops, and monitoring metrics like change failure rates and recovery times.
