Continuous Delivery and DevOps in IT
• Continuous Delivery is s-s-s-Scary!
Because change is scary
Because the unknown is scary

Continuous Delivery and DevOps in IT
• Continuous Delivery is s-s-s-Scary!
Because change is scary
Because the unknown is scary
• If it’s painful, do it more often!
• Develop IT capabilities like software
Decompose the problem space
• Treat infrastructure as code
Automate almost everything
• Remember Conway’s Law
Architectures reflect organizational
structure.

DEFECTS
Challenges for a Large Enterprise
• Cultural Change
Employ an educational campaign
Inspire by example
Remove the training wheels
(Don’t be afraid to fail & fail early)
• Technology Transformation
The problem of choice – simplify it
Fighting the decisions of the past
Not a silver bullet
• Position Yourself for Success
Continuous delivery is a journey
Leverage your strengths & acknowledge your
weaknesses
Be pragmatic - SMART.

Achieving Mindshare
• Think pervasively
Management and individual contributors
• Eye on the prize
Beware of scope creep
Demonstrate benefit
• Socialize
Success and failure.

Dealing With Legacy
• IT assets are not a fine wine
• Mind your technical debt
• Agility means rework more often,
but less rework overall
• Get vendors on board
• Get customers on board
• Last resort: Isolate and confine the
problem areas.

Being Pragmatic
• Take one step at a time
• Your adoption strategy should exercise the same
principles you intend to embrace
• Test the waters
• Develop your own blueprint (or use others’)
• Get your bearing using a maturity matrix…

Meshing Operations and Continuous Delivery
• Build cross-functional teams
And sidestep Conway’s Law
• Artifacts become the handoff
Create a pipeline of work
Employ build promotion
• Goal: Every build is deployable
No last-minute tweaks before release
• Deploying COTS? No problem!
Skip code compilation
Include everything else.

Considerations for Successful CD Adoption
• Organizational Structure
Cross-functional teams improve communication
• Software Architecture
Dependency Injection
Microservices
Feature toggles
• Infrastructure Capabilities
Virtualization, SDN, Cloud
• Development Platforms
Pick tools for productivity, not just coolness
• Gamification to increase productivity
Work environment fun = good
Work itself fun = better
• COTS Applications
CD is not just for software development.
