If everything seems under control, you're not going fast enough.Mario Andrettiracing legend* 1940

Placing a new offering on the market first is often the only way to generate margin. Before competition picks up.

44

In today’s digital economy, new offerings are made possible or strongly supported through software.

55

DevOps is about getting new code to the market as fast as possible.

66

It is not a technology, it is a cultural mindshift, bringing Dev, QA and Ops very closely together.

77

However, certain technologies and practices can be used to accelerate this process.

One of the most influental contributions to the SW-defined economy was published by Netscape-Founder Marc Andreesen four years ago, in August 2011

In it, he demonstrated the growing influence and value of SW-based companies in the global economy: Amazon, Netflix, Spotify, Skype, Google, LinkedIn

And he probably was right: Judging by the usage of social media services alone, we are looking at• 1.9 B users today• 2.1 B in 2016• 2.5 B in 2018

2.5 B are a third of the Earth’s population

New and existing companies choose software to disrupt the traditional way of doing business

• Either by enhancing the possibilities of traditional offerings

• Or by entirely substituting them

Uber.com combines two features of the new, SW-enabled economy:

• It is easy to do business with – trough easy-to-use software

• Its services are provided by a crowd of individual contributors

This is where DevOps kicks in.

DevOps is not a technology.

DevOps is a cultural and operational model that fosters collaboration to enable high-performance IT to achieve business goals.

2121

DevOps is not a technology.

It’s the principles of agile development applied to the entire IT lifecycle.http://www.agilealliance.org/the-alliance/the-agile-manifesto/

And smart technology can help DevOps.

2222

So are we to become anarchists?

http://www.agilealliance.org/the-alliance/the-agile-manifesto/

2323

And blow up all the structures we have become fond of?

Such as ITIL, (IT Infrastructure Library), the gold standard to organize IT operations in Enterprise environments?

2424

Well,kind of.

2525

DevOps constitutes a mindshift in understanding how Dev and Ops collaborate.

Keep the concept, drop the practice.if you separate out the

logical model of ITIL from the physical “best” practices (...) beneath it, ITIL is a valuable resource

DevOps is not about application performance.

DevOps is not about application performance.

DevOps is about bringing SW-based services to the market fast and in a good quality.

Developers know, what Operations need.

They should use Puppet to do configuration management and automate their Datacenter.

We’ll write our deployment scripts in Ruby so Operations can read what we are doing.

Operations know, what Developers need.

They want push button environments.

We need a system to replace all systems.
