DevOps for Digital Leaders DevOps Metrics With any IT-driven methodology or program, measuring the effectiveness in a business context is critical. But since DevOps isn’t a formal framework, organizations have little guidance in determining what metrics should be used. This can be problematic and lead to a number of suboptimal practices: • Efficiency status-quo—The IT team falls back to metrics traditionally used to demonstrate technical proficiency in meeting stability and resilience goals. Although these are not necessarily wrong, DevOps metrics should also demonstrate how new processes and automated technologies are impacting the business—for example by speeding time-to-market and reducing lead times.
Programmable Infrastructure —Also known as Infrastructureas-code, this allows teams to write code to manage configurations and automate infrastructure provisioning. Rather than using manual methods or scripting to build development ready infrastructure, teams can write code in languages with which they are familiar, together with familiar practices such as version control and automated testing to reduce errors. Unlike scripting, which is primarily used to automate static steps, programmable infrastructure with its descriptive languages allows developers to code processes that are far more versatile and adaptive.
As in traditional manufacturing, there are many waste indicators in IT’s own software factory. In development, partially completed work can become obsolete before it finds its way into production and should be exposed to ensure it doesn’t degrade or corrupt the code base. In operations, excess on-premise server infrastructure acquired as a fail-safe to address unanticipated performance problems could be avoided by establishing monitoring in pre-production. 39 40 Chapter 3 | DevOps Foundations ■ Note Costs can accumulate substantially when agile teams acquire specialist tools.
