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.

DEPENDENCIES


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
