DevOps: Extending Agile to Increase Synergy Between Development and Operations

Published: 25 August 2011

ID: G00214696

Analyst(s): Sean Kenefick

Summary

Enterprise IT groups have started migrating to agile methodologies and are seeing good results. By performing requirements creation, development, and testing in parallel, development teams focus completely on business value. But agile only addresses half the problem that many groups face: Because agile leaves out operational staff, developers lose a crucial mechanism for feedback. Sean Kenefick shows how DevOps applies inherited agile principles of discipline, collaboration, and early feedback to tasks such as deployment, environment configuration, monitoring, and maintenance.
