Agile software development has broken some of the silos between requirements analysis, testing and development. Deployment, operations and maintenance are other activities that have suffered a similar separation from the rest of the software development process. The DevOps movement aims to eliminate these silos and encourage collaboration between development and operations.
DevOps is a concept that has been around for a decade. It's one of those things everyone talks about, but not everyone understands or implements correctly. We may hear how it is intrinsically related to agile software development; we are told that it will drastically improve a company's ability to launch software quickly and efficiently. We know by its name that it implies some kind of integration between development and operations, and a little research shows that it is a culture instead of a tool or methodology.
So, why, in the information age, are DevOps often implemented incorrectly? Why are its fundamental principles often misunderstood? When analyzing, what is the DevOps culture and how should it be?
Faster implementations and feedback loops get to the heart of what developers want the code comes from their laptops into the hands of users much faster and continuous delivery allows iterations and rapid improvements. The best place to start is to track the improvements in the change wait time during the first pilots:
Ops benefits when developers work closely with them. It may be useful to start by agreeing on a common tool chain and having the two groups work together to adopt the same tools used in development to integrate, test and deploy the infrastructure code. This allows developers to participate more actively in implementations and troubleshooting, further eliminating old barriers while improving speed and reliability. Tracking several metrics that concern Ops will highlight earnings for the entire team, including Dev and QA:
1. Integrate the teams creating a collaborative environment and establishing common objectives.
2. Continuously develop agile employees who gain experience.
3. Promote shared learning through transparency.
4. Develop team players who think beyond their own area of expertise.
5. Empower multi-skilled workers who understand the functions of others and share responsibility.
