What	is	DevOps?
„It	works	on	my	workstation!“	
(Developer)
„The	server	is	ok.	It’s	the	code!“	
(System	Administrator)
Problem	on	Production!
„DevOps	only	involves	
developers	and	system	
administrators!?“
„DevOps	is	a	role!?“
„DevOps	is	a	team!?“
„DevOps	is	a	set	of	tools!?“
„DevOps	is	a	hype!?“

real business value. High-performing IT organizations have a strong and positive
impact on the overall performance of the organizations they serve. This year’s
report also tells us:
• High-performing IT organizations deploy 30x more frequently with 200x shorter
lead times; they have 60x fewer failures and recover 168x faster.
• Lean management and continuous delivery practices create the conditions for
delivering value faster, sustainably.
• High performance is achievable whether your apps are greenfield,
brownfield or legacy.
• IT managers play a critical role in any DevOps transformation.
• Diversity matters.
• Deployment pain can tell you a lot about your IT performance.
• Burnout can be prevented, and DevOps can help.
1. Executive Summary
The fourth annual State of DevOps Survey confirms that IT performance provides
real business value. High-performing IT organizations have a strong and positive
impact on the overall performance of the organizations they serve. This year’s
report also tells us:
• High-performing IT organizations deploy 30x more frequently with 200x shorter
lead times; they have 60x fewer failures and recover 168x faster.
• Lean management and continuous delivery practices create the conditions for
delivering value faster, sustainably.
• High performance is achievable whether your apps are greenfield,
brownfield or legacy.
• IT managers play a critical role in any DevOps transformation.
• Diversity matters.
• Deployment pain can tell you a lot about your IT performance.
• Burnout can be prevented, and DevOps can help.

„There	is	a	clear	and	accepted	
definition	of	DevOps!?“
„DevOps	is	a	culture,	movement	or	practice	that	
emphasizes	the	collaboration	and	communication	of	
both	software	developers	and	other	information-
technology	(IT)	professionals	while	automating	the	
process	of	software	delivery	and	infrastructure	changes.	
It	aims	at	establishing	a	culture	and	environment	where	
building,	testing,	and	releasing	software,	can	happen	
rapidly,	frequently,	and	more	reliably.“
https://en.wikipedia.org/wiki/DevOps
Requirements

Verification
Maintenance
What	about	now?
Manifesto	for	Agile	Software	Development	
Individuals	and	interactions	over	processes	and	tools

Working	software	over	comprehensive	documentation

Customer	collaboration	over	contract	negotiation

Responding	to	change	over	following	a	plan	
That	is,	while	there	is	value	in	the	items	on

the	right,	we	value	the	items	on	the	left	more.
