DevOps
DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through development and into production support. It aims to deliver software incrementally from the start of a project through continuous delivery in short two week cycles called iterations. Adopting DevOps, even for large mainframe shops, can lead to significant gains like reducing critical defects by 80% and improving maintenance efficiency by 20% in just 18 months. DevOps establishes a continuous feedback loop that speeds up development and deployment while maintaining quality, moving away from traditional waterfall methodologies.

Agileis a time boxed, iterative approach to software delivery that builds software incrementally from the start of the project, instead of trying to deliver it all at once near the end What is DevOps?

- 10. 8/18/2017 10 IBM DevOps forthe Mainframe DevOps is not just for distributed platforms. IBM has a DevOps strategy for large enterprises (usually mainframe shops) too. Nationwide, a longtime mainframe shop, is an early adopter of DevOps and already is reporting significant gains: reduction in critical software defects by 80% and a 20% efficiency gain in its maintenance and support operations in just 18 months. DevOps, an agile methodology, establishes a continuous feedback loop between software development and deployment/operations that speeds development and deployment while ensuring quality. This is a far cry from the waterfall development methodologies of the mainframe past.
