How?
DevOps
DB Systel | Schlomo Schapiro & Hendrik Pahl | @schlomoschapiro & @hendrik_pahl | 16.10.20187

DevOps is
… if every person uses the same tool for the same job
… codified knowledge - everybody contributes his part to common automation
… if all people have the same privileges in their tooling
… if human error is equally possible for Dev and Ops
… replacing people interfaces by automated decisions and processes
... a result

How?
Cloud Platforms
In your Data Center:
• do you have an API for every function?
• can you provide „just enough“ resources
and scale up/down without delays?
• can you scale costs by usage and
achieve full cost transparency?
Good cloud platforms can be built on-premise, require extreme scale out.

How to start?
• Set a goal, e.g. „2 deployments per day“
• Identify impediments
• Replace impediments through automation
• Believe that you can do it, let failure make
you stronger
• Repeat until done
• Build tools that are useful products:
• Continuous Delivery as a Service
• Cloud Platform as a Service
• Proxy, DNS ... as a Service
• Company concerns (security, governance,
compliance) must be part of the continuous
delivery pipeline24
