No IT Left Behind - Connecting the Software-Defined Data Center to Multi-Modal IT
Download as PPTX, PDF1 like436 views
This document discusses moving from a traditional IT model to a multi-modal model that incorporates elements of DevOps. It outlines the stages of progress made, including building infrastructure, realizing more was needed, and adopting a multi-modal approach. The approach uses tools like Ansible, Docker, and collaboration methods like JIRA and HipChat. After 9 months of applying this approach, backlogs were cleared, changes became scripted and containerized, and containers as a service were achieved. Lessons included establishing early metrics, embracing change and failure, and that technology enables but is not a solution on its own.

- 4. Focused on Developing Solutions for the DoD, DHS and other Federal Agencies • Wide Range of Compliance Challenges SETTINGTHE STAGE 4
- 5. Diverse Staff • 300+ Software Engineers • 150+ Field Personnel • 100+ Active Projects at any time SETTINGTHE STAGE 5
- 6. 150+ Corporate Systems • 3rd Party and Homegrown! SETTINGTHE STAGE 6

- 20. • Responsiveness and reliability are the same thing! MULTI-MODALOPTION Treat All Systems as Agile 20
- 21. • Each piece of the enterprise is at a different place on the continuum and will move forward at a different speed (crawl/walk/run) • Dynamic on-premise environment that supports flexible, timely and relevant capabilities while adhering to a wide range of compliance challenges MULTI-MODALOPTION DevOps approach spanning the entire enterprise 21
