Industry Transformations• Software industry changing – more service oriented

• Applications• Platforms• Infrastructure

• Greater Adoptions of Lean and Agile• Technology changes

• Growth of the cloud DevOps is not just for the cloud industry

Lean Thinking• Holistic (or “wholistic”)• Adherence to quality• Rapid feedback loops• Empowered and learning organization• Exploit variance• Eliminate waste• Make decisions as late as possible• Deliver value quickly and frequently

Agile – Development delivers faster

Sprint

Daily Scrum

Product Backlog

New Functionality

• Product development - development and test joined• Business joined in as well.

Did anyone tell Ops?

Operations: • Stability trumps change

Silos

DEV OPS

Different Managers

Different Business Units

Different Companies

Why Does it Matter?

CODE HAND-OFF

• Developers with no incentive to make site easier to support operationally

• Operations who inhibit development of new functionality to keep stability

• Resist deploying new versions/create roadblocks for implementation to reduce risk.

• Product Stability and New Feature Delivery Suffer

Different vision, different mission – Tear down that wall!

Business needs• More frequent product deployment

• Operations needs to get on the agile train• Faster everything

• Product Deployments• Testing• Development • Feedback loops

• What about stability? What about operations time? • Enter DevOps

What is DevOps• Dev + Ops

• The union of functionality and operability• The overall application of the lean mindset across product

development and operations teams• Developers to incorporate

Operations functionality into the product Operations mindset to their work Perform ops work to some degree

• Operations To be involved early and through the development life cycle Treat operations as a product

– Infrastructure as code– Support continuous processes

• Breaking down one more silo• extending lean further across the value stream

DevOps is also…• Commonly used term to describe

• The transformed operations teams• The community of these like-minded individuals

Dev and Ops need to • Automate everything they can

• Deployment infrastructure• Product deployments• Testing• Integration • Development services• Development

• Risk mitigation• Test every change immediately • Process and react to feedback quickly

Transformation• Leadership well versed in lean

• Development strategy to support continuous integration• Deployment strategy to support lean deployment

Small queues Minimum wait time Technical excellence Rapid feedback Understand and exploit variance

Deployment is Core• Deployment is no longer a contextual exercise• Product vision needs to embody deployment concepts:

• Lead time - time from concept to value delivery• Speed of deployment• Reduce cost/time to deliver• Reduce time/cost to test• Increase test coverage• Increase technology/environment utilization• Minimize deployment related downtime• Minimize deployment time issues (weekend long deployment marathons)• Minimize roll-backs of deployed Apps, Platforms, Infrstructure• Increase the ability to reproduce and fix defects• Minimize ‘mean-time-to-resolution’ (MTTR) of production issues• Reduce defect cycle time• Reduce challenges related to Dev and Ops collaboration

Product Management / Product Owners

• Roadmap for development and deployment• Architectural vision needs to support modularity for

• Build time• Deployment time• Run time

• Product Owners • Support both functionality and operability • POs for Dev and Ops work together• Understand that “non-functional” requests are as important as

new features• Support overall corporate strategy and metrics

Release Planning and Execution• Release Planning

• Include DevOps vision• Agile practices for Dev and Ops

• Scrum and/or Kanban• XP practices

• Team structures• Imbed Ops personnel in the Dev Scrum Teams

• Source code management• Branch as late as possible• Keep to one stream

• Source Build and Continuous Integration

Technical Stuff• Source code management

• Branch as late as possible• Keep to one stream

• Source Build and Continuous Integration• Automated Testing



• Continuous Delivery• Infrastructure as code• Results based deployment decisions and time based

deployment decisions• Automated, on-demand deployment• Roll back, hot swap systems• Monitoring systems• Deployment documentation



• Source Build • Automated, on-demand build• Accessible build• Build infrastructure as code

• Automated Testing• Test harness as code• Automated, on-demand testing• Collective ownership
