Tools

● Chef/Puppet● Jenkins● Travis-CI●

The problem with tools..

● Don't imply that you have skill● Doesn't solve the problems DevOps addresses● Far too often see as a substitute● Lots of people trying to sell you tools● Tools are still indispensable

Teams

● No such thing as a DevOps Team● You can't silo your 'DevOps' efforts●

DevOps isn't...

● A Job Title● A tool● Something you can get from a vendor● A team● Easy

So what is DevOps?● Adopt the new philosophy. We are in a new economic age. Western management must awaken to the

challenge, must learn their responsibilities, and take on leadership for change.● Cease dependence on inspection to achieve quality. Eliminate the need for massive inspection by

building quality into the product in the fi rst place.● Improve constantly and forever the system of production and service, to improve quality and productivity,

and thus constantly decrease costs.● Institute training on the job.● Institute leadership The aim of supervision should be to help people and machines and gadgets do a

better job. ● Drive out fear, so that everyone may work effectively for the company. ● Break down barriers between departments. People in research, design, sales, and production must work

as a team, in order to foresee problems of production and usage that may be encountered with the product or service.

● Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the work force..

● Eliminate management by objective. Eliminate management by numbers and numerical goals. Instead substitute with leadership.

● Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility of supervisors must be changed from sheer numbers to quality.

● Remove barriers that rob people in management and in engineering of their right to pride of workmanship. This means, inter alia, abolishment of the annual or merit rating and of management by objectives

● Institute a vigorous program of education and self-improvement.● Put everybody in the company to work to accomplish the transformation. The transformation is

everybody's job.

The Goal

We aren't special

● We've had a tendency to think of ourselves as special and unique because of technology

● The reality is that because we've designated ourselves as special we've failed to take advantage of what others have learned before us.

The future....if we adapt..

Easier Definition

● Culture● Automation● Measurement● Sharing

Primarily – it's cultural

● Automation, Measurement, and Sharing don't matter if you don't get culture right.

● First focus is pulling down the walls between developers and operations. They can't continue to be silos.

DevOps cultural battle is not won overnight

● Continuous, small, improvements. (Kaizen)● Forklift changes are often disruptive.
