Right on the heels of the Manifesto for Agile Software Development, a new movement with the moniker DevOps has further advanced software delivery. Although the Agile software development movement brought iterative and incremental concepts to our industry, in many organizations its reach was relegated to only the application development teams. In many cases, this moved the bottlenecks in organizations from application development to release management, IT operations and business program and portfolio management decision making. This local optimization leads to real world application of Agile software development being perceived as unsuccessful and increased probability of being thrown away for the comfort in the illusions of control of plan-driven approaches. The promise of DevOps is to further improve our ability to make holistic optimizations from business to software delivery to operations and ultimately increase feedback into our business decision making processes. This promise involves the application of The Three Ways as described by Gene Kim: Flow, Feedback and Continuous Experimentation and Learning. Even for those that were able to take advantage of Agile software development we can not sit on our laurels. We must embrace continuous improvement in order to fend off the effects of “Software is Eating the World” as Marc Andreessen pronounced. DevOps provides a view on the culture, practices, tools and processes for how valuable software is delivered, operated and evolved to enable competitive advantage.

EMPIRICAL PROCESS CONTROL
INSPECTION
ADAPTATION
VISIBILITY
Any aspects of the process that affect the
outcome must be visible and known to everybody
involved in the project process.
Various aspects of the process be inspected
frequently enough so that unacceptable
variances in the process can be detected
Adjust the process if one or more aspects of the
process are in an unacceptable range

MODELING, AND CONTROL

EXTREME PROGRAMMING

12. Agile, Innovation & Beyond!
Yes, and there are still plenty of problems to solve…
Why are we running
2 week iterations if
we want to deploy
daily?
We still have to wait
for Operations to
provision and deploy
software and it takes
longer than we’d
like.
We don’t own or
update the
infrastructure that our
apps run on so we
can’t guarantee that
we can recreate the
environment.
Those “agile” teams
keep launching new
app versions and
don’t understand
what a risk that is to
our infrastructure.
Release processes
are still mostly
manual and it is
common to have
errors after
deployment to
production.

CASE STUDY: WEB PROPERTY
• 180+ person “Web 2.0” product organization
• Existing Waterfall SDLC focused on 6 month release cycles
• Delivery taking longer than 6 months in most cases
• Quality issues increasing in production
• Goal: Be more responsive to users & competitive threats
• Transitioned delivery in 3 months to incorporate release management and QA
into Feature Teams
• After 4 months able to release into production every week
• Used Continuous Delivery pipeline to validate product changes daily

DEVOPS CULTURE
http://martinfowler.com/bliki/DevOpsCulture.html
Article by Rouan Wilsenach @rouanw
• Increased collaboration across broader
organizational roles
• Goes beyond requirements analysis,
testing & development
• DevOps adds release engineering,
production monitoring & configuration
management (at least) in a shared
responsibility team
• Self-organizing teams: autonomous,
cross-functional & self-transcendent

18. Agile, Innovation & Beyond!
• 700+ person organization
• Millions of line of code + hundreds of unique apps & services
• Continuous Integration server involved thousands of jobs & 1M+ builds
per year
• 9-18 month overlapping release cycles
• Found opportunity to not branch in SCM for each overlapping release
• After 2 year transition to Continuous Delivery pipelines and deployment
automation, Ads Platform can released to 20+ data centers globally
every day
• After 4 years, all teams across entire company can release to production
with no human intervention for 100% of deployments

8 Principles of Software Delivery
• Create a repeatable, reliable process for releasing software
• Automate (almost) everything
• Keep everything in version control
• If it hurts, do it more frequently, and bring the pain forward
• Build quality in
• Done means released
• Everybody is responsible for the delivery process
• Continuous improvement

An approach to safely deploy new versions
of software to production and testing its
behavior before committing to full rollout.
• Deploy updated version “Canary”
• Divert some traffic towards “Canary”
either direct or replicated
• Replace previous version with “Canary”
if behaving as expected

FEATURE TOGGLES
• Problem: Need to deploy with some
features that are not sufficient or
validated with customers
• Introduce feature behind toggle:
– ON: Show to authorized users
– OFF: Don’t show to users
