Most conversations about CI/CD reliability start in the wrong place. Teams debug flaky pipelines, investigate intermittent failures, tune alerting thresholds and optimize build times. All of that work is legitimate. However, the decisions that most directly determine whether a CI/CD pipeline is reliable or not were made months or years earlier, during tool selection. By the time teams are debugging pipeline reliability, they are usually dealing with the downstream consequences of upstream decisions that seemed reasonable at the time. The software development tools a team chooses shape their CI/CD pipeline in ways that are not always visible during evaluation. Understanding those connections is the most practical starting point for teams that want reliable pipelines rather than better pipeline firefighting. The Integration Surface Problem Every tool in a software development stack creates an integration surface. Integration surface is the set of connections a tool has with oth...
Today, most DevOps teams do not think too much about their approach to risk. Usually, the typical attitude focuses on what to add to reduce risk further. In other words, “Can we add more tests? Can we deploy more carefully?” More tests, more processes and less risk are all obviously good things. Or are they? […]
