• Sharing
Monday, June 13, 2011
Devops Problems
• Bottlenecks
• Wait Time
• No Measurement
Monday, June 13, 2011
Devops Anti-Patterns
• Long Release Cycles
• Handoffs Between Ops, Dev,Dba, Test,etc..
• Works in Stage but not in production.
• Preparing environments for release takes a long time.
• Config files are updated manual.
• Different systems OS, Middleware, App versions.
• Can’t tell what systems are running what versions.
• Manual Documentation
Monday, June 13, 2011
More Anti-Patterns
• Silod Teams
• Fractional Systems
• Dependency Hell
• Scheduled Builds
• Manual Database Builds
• Large Test Datasets
• Manual Tests
• Manual Documentation
• Manual Deployments
• Throttled Deployments
• Manual Rollbacks
• Don’t Version Everything
• Code Freezes
• Golden Images
• Mixed Automation
• No Deprovisioning Process

Devops Enemies
• Misalignment of Incentives
• Latent Demand
• Non Functional Requirements
• Siloization
Monday, June 13, 2011
Misalignment of Incentives
• Senior management driven by total revenue
• Sales is driven by compensation
• Development is driven by delivery
• Quality Assurance is driven by defects
• Operations is driven by uptime
Monday, June 13, 2011
Latent Demand
Situation where demand cannot be met: a business environment in which demand for a particular product cannot be met by existing suppliers or is temporarily suppressed
Monday, June 13, 2011
Devops InducedDemand
• What if IT could create an environment where consumers of IT were informed and felt empowered?
• What if IT gave them the freedom to get things done?
• What if freedom and a getting-things-done attitude became habit forming?
Monday, June 13, 2011
Non Functional Requirements
• Security
• Backups
• Availability and Performance
• Upgrades
• Configuration Management
• Monitoring and Logging
• Disaster Recovery
Monday, June 13, 2011
Siloization
• Security
• Development
• Operations
• Testing
• Quality Assurance
Monday, June 13, 2011
Siloization
• Departments are like tribes
• Explicit rules of the tribe
• Implicit rules of the tribe
• Sociability
• Solidarity
Monday, June 13, 2011
Devops Memes

• Infrastructure as Code
• Done means Deployed
• SDLC as Infrastructure
