DevOps

DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.1

DevOps has become one of our industry's most popular buzzwords. Yet, surprisingly, there is little consensus as to what DevOps means beyond the high-level vision of tighter and more effective collaboration between development teams and operations teams. While DevOps might mean different things to different organizations, there is an emerging core of best practices that further its goals of enhanced collaboration to produce better software.2

Devops is About CAMS3

• Culture - People and process first. If you don’t have culture, all automation attempts will be fruitless.
• Automation - This is one of the places you start once you understand your culture. At this point, the tools can start to stitch together an automation fabric for Devops. Tools for release management, provisioning, configuration management, systems integration, monitoring and control, and orchestration become important pieces in building a Devops fabric.
• Measurement - If you can’t measure, you can’t improve. A successful Devops implementation will measure everything it can as often as it can… performance metrics, process metrics, and even people metrics.
• Sharing - Sharing is the loopback in the CAMS cycle. Creating a culture where people share ideas and problems is critical. Jody Mulkey, the CIO at Shopzilla, told me that they get in the war room the developers and operations teams describe the problem as the enemy, not each other. Another interesting motivation in the Devops movement is the way sharing Devops success stories helps others. First, it attracts talent, and second, there is a belief that by exposing ideas you can create a great open feedback that in the end helps them improve.
