Deployment Frequency: The Key to High-Performing DevOps
To measure DevOps success, Deployment Frequency is a critical yardstick. It is one of the four DORA (DevOps Research and Assessment) Metrics that measure software delivery performance. The more frequently an organization can successfully deploy code to production, the more agile and responsive it can be to changing market demands, customer needs, and security challenges.
The Change Failure Rate Playbook
In the world of DevOps, metrics are signposts that guide engineering teams toward better practices and improved software delivery. One of the critical metrics defined by the DevOps Research and Assessment (DORA) group is the Change Failure Rate (CFR). This metric measures the percentage of deployments that result in a failure in production, providing a clear indicator of the stability and reliability of software releases.
Understanding Mean Time to Recovery
When thinking about software reliability, the intuitive approach might be to aim for "zero failures." While this sounds good on paper, it often leads to paralysis by analysis. Instead of striving for an unrealistic ideal of no failures, focus on how quickly and effectively you can recover when things go wrong. This is where mean time to recovery (MTTR) shines as a practical and motivating metric.
From Commit to Production: How to Speed Up Lead Time for Changes
If you've ever fixed a bug or built a new feature, only to watch your code sit in limbo for days or even weeks before reaching users, you’ve experienced a slow Lead Time for Changes firsthand. So let’s understand what LTC is, why it matters, and how you can improve it using DevOps techniques.
How Do You Measure DevOps?
DevOps is a way of working together to make building and running software easier and faster. The best way to measure how well you are doing DevOps is a set of measures called DORA metrics. They show where your team is working well, and areas to improve your DevOps practices.
