DevOps

9. 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

10. 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, on-premise cloud requires extreme scale out.

Ausgangssituation und Ziele
DB Systel GmbH | 2D/d | Dr. Martin Strunk | Programm ShapeIT | 06.02.20182
§ Durch Neuausrichtung der Softwareentwicklung soll ein Potential von ca. 45 Mio. € pro Jahr realisiert
werden (Konzernbeschluss DB Enterprise Cloud)
§ DevOps ermöglicht durch Automatisierung eine erheblich verbesserte Time-to-Market und wird
zunehmend zum Marktstandard
§ Im Vorprojekt Softwareentwicklung goes Cloud wurden die möglichen Zielszenarien erarbeitet und
verprobt und ein Zielbild für die zukünftige Produktion festgelegt
§ Unsere Vision: „You build it, you run it! Um unsere Time to Market radikal zu verkürzen, arbeiten wir in
stehenden, cross-funktionalen Teams, die Services gemeinschaftlich als Team in eigener Verantwortung
entwickeln und betreiben.“
§ Ziele:
§ Maximal 1 Stunde zwischen Idee und Livegang eines neuen Services
§ Jede neue Anwendung kann mindestens 2 Deployments pro Tag liefern
§ Implementierung des DevOps Produktionsmodells durch Bereitstellung und Betrieb der
notwendigen Werkeuge, Schaffung der erforderlichen organisatorischen Rahmenbedingungen
und Förderung des damit verbundenen kulturellen Wandels
§ Nachweis der Nutzen-Potentiale, die mit der verbesserten Time-to-Market gehoben werden.

30. How to start?
30
• Set a goal, e.g. „2 deployments per day“
• Identify impediments
• Replace impediments through automation
• 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 pipeline
