Dave Sayers
Applying DevOps principles in established corporate organisations
“There is a difference in DevOps approaches between organisation
where IT is not a core competency – and those where it is”
Agenda
• Why?• Characteristics of traditional and
modern firms• Foundations of DevOps approaching in
the enterprise• Importance of configuration
management• Brief look forward
Why?
• Fast flow of planned change• Efficiency• Repeatability• Audit• Compliance• Security, etc.
Management approach
Heterogeneous Dev and Ops teams
Low frequency of releases
Established Organisations
• Heterogeneous Environments• Focus on integration• Top down approach• Low frequency of releases• Manual processes• Heterogeneous Dev and Ops
teams• “Buy not build”
Characteristics of Modern firms
• Smaller number of decoupled products• More homogeneous dev and ops teams• Built with automation in mind• High deploy rates• Built on modern / opensource
technology

Model Driven Deployments
• To ensure consistency – always deploy the same thing!• Data driven
• Templates created that define infrastructure or application configuration
• Contain the complete configuration for a target technology
• Deltas become part of the template – so configuration changes are not made in isolation
