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

Analyst & Customer

Design

Architect

Development

Developer

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

Release

IT Operations

More business and user

involvement during

design and build!

Sprint Backlog

Product Backlog

Potentially Shippable

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!

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.)
