Reminder: What is DevOps?

The typical waterfall Project
Problem with typical waterfall project:
 Long QA feedback loop
 Lack of collaboration
 Inability to change direction
Requirements

Integration + QA
Tester
Release
IT Operations
Months ! Requirements have
changed !
You can’t just ask customers what
they want and then try to give that to
them. By the time you get it built,
they’ll want something new.
Steve Jobs

The Agile Project Solution
Problem with typical Agile project: the last mile
 Manual deployments, operations unexpected delay
 Insufficient configuration management
 Infrequent, manual, error prone deployments
Integration + QA
Tester

IT Operations
More business and user
involvement during
design and build!

What is a DevOps Pipeline?
Define Implement Build Integrate Validate Release Deploy Operate
Pipeline / Business Value Stream
Speed
Continuous Delivery
Continuous Integration
Agile
Continuous Deployment
The processes and activities we do to deliver value (software)
i.e. get required features into users hands

Example Pipeline for Application Features / Stories
Define
•User Story
•Acceptance Criteria
•Schedule
•Etc.
Implement
•Code
•Unit Test
•Check-in
•Update Work Items
Build
•Compile
•Static Analysis
•Automated Unit Test
•Package
Integrate
•Provision, Deploy, Configure
•Restore / Gen Test Data
•Launch Automated Tests
•De-provision
Validate
•Restore / Migrate / Upgrade Data
•Activate Supervision (B & IT)
•Performance, Load, Stability Tests
•Security & Supervision Tests
•De-provision
Release
•Signoffs
•Help desk updates
•Network / Security CRs
Deploy
•Backup / Migrate Data
•Activate Supervision & Operations
•Health, Security, Manual Tests
•Staging Switch / Redirect
•Health & KPI monitoring
Operate
•Alert / Issue Handling
•Capacity Mgt / Provisioning
•Testing in Production
•Value Metrics, A/B Testing,
Feature flag activation
•Reporting
Capable of pulling features
through the system, in
release batches or
individually.

Pipeline considerations
 Pipeline can be very different depending on many factors
 Technologies chosen, target platform, toolsets available
 Your organizational structure, processes and culture
• Manual procedures and approvals might still be needed.
 The architecture chosen and how components are decoupled
• Microservices, classic 3-tier, containers, PaaS, resources…
 Your own need for speed
 There is no generic pipeline. It is not just a question of tool choices.
 Design your pipeline as a value stream and apply Lean principles to
optimize it. Do not just deploy tools or automate blindly!
 Remember that Dev & Ops should be collaborating during complete
lifecycle!
 Demo

Advanced DevOps Pipeline Features
The pipeline should ideally enable the application to do things like…
 Split user traffic between multiple concurrent versions
 Test new features and ideas
 Measure increase/decrease statistics
 Leverage results to enhance application user
experience
 Control features with Feature Flags
 Deploy multiple revisions of the same code
 Slowly send traffic to new version
 Monitor new version for errors or issues
 Full cut over once new version has been fully
tested and assured
 Easy failback to later version
 Smaller code, faster to build & deploy
 Individually scalable components
 Independent and flexible development, testing,
deployment cycle among services
 Containerization making it easier to optimize
 Choose best technology stack per service
 Business monitoring
 Application, Service & Process monitoring
 VM & infrastructure monitoring
 Synthetic user experience monitoring
 A/B testing results (conversion inc./dec.)
