“Regardless of industry your company is now a software company, and pretending that it’s not spells serious peril…That leads to an increasingly urgent and overarching mandate: Your company must, using software and technology, become as responsive and agile as your customers.”
David Kirkpatrick Now Every Company Is A Software Company

Resilience, security, scalability, deployability,
testability are fundamentally architectural
concerns

What we really need to do is be able to build, and operate systems that are resilient, secure, and capable of rapid
change at scale. Hence: DevOps
a cross-functional community of practice dedicated to the study of building, evolving and rapidly changing secure, resilient systems at scale - Jez
A cultural and professional movement, focused on how we build and operate high velocity organizations, born from the experiences of its practitioners. -Jacobs

Top predictors of IT Performance
peer-reviewed change approval process
version control everything
proactive monitoring
high trust organizational culture
win-win relationship between dev and ops

17
Highest Correlation with IT Performance
All application and infrastructure code and configurations are in a version control system
Effective logging and monitoring across all environments
Developers merge their code daily
Developers break features into to small, incremental changes

As leaders
• build cross-functional teams and a spirit of cooperation • share risk across all the silos • experiment in novel ways to find solutions • use failures as an opportunity to learn not place blame
19
so in summary
• every company is a software company • it is difficult to predict the impact of features and changes • so we need the ability to rapidly test and alter course based on feedback • which requires software defined infrastructure • and close partnership between development and operations
