Conclusions

• We all want better designed, higher quality, resilient software, and we want it as frequently as possible
• DevOps is part of the process - the goal of DevOps is facilitating a continuous delivery process for your custom written software
• You get a platform either way, it’s just a matter of who has the responsibility to maintain the platform
• A cloud native platform automates as much as possible and enforces a process that removes variability leading to speed and resilience
• With Pivotal Cloud Foundry, “DevOps” occurs at the application layer (the most valuable layer), while platform operations (a very small team) keeps the platform up and running

Organizations are held back by an agility gapWhat is your IT organization's
role in business innovation?

Only 25% of respondents felt that their companies were innovating in agile ways.
Things are better, but not everyone has caught up

Technical Goals that lead to DevOps1. Delivering software that runs on the Internet (mobile, web,
etc.)2. The pipeline is the factory, from concept, to code, to
production3. Faster turns, while maintaining quality, uptime, performance
– Lean approach to entire process– Shorten time to customer value– Keep the site up, resilience vs. failure
Consequence: requires Development & Operations to combine
Sources: see The Practice of Cloud System Administration, chapter 8 for an in-depth definition and discussion. Also, see Damon Edward's 2012 piece "Use DevOps to Turn IT into a Strategic Weapon.” Also, The Phoenix Project for a story of DevOps in the style of The Goal.6
DevOps, the word defines itself

(1.)DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.
(2.)DevOps is also characterized by operations staff making use of many of the same techniques as developers for their systems work.
