DevOps: We Can Do Better

 Fixing yet another ‘organizational silo’ problem, this time
between pre-production and go/post-production teams
 Widely acknowledged as a process and ownership problem.

Continuous Integration is the Starting Point

 Continuous integration is in poor shape at many organizations.

 Common issues include:
 Splintered version control systems including old ones like PVCS, CVS, etc.;
failure to consolidate to newer choices: git, svn, etc.

 Splintered build systems even on same platform (Ant, Maven, etc)

 Running continuous build system – but allowing broken builds to exist

 FIX CONTINUOUS INTEGRATION BEFORE MOVING ON

Continuous Testing is a Must!

 Continuous Testing is in AWFUL shape at most companies!

 Create and run basic automated tests with builds:
 Unit tests (Junit, Nunit, etc.)
 Integration tests (SoapUI, etc.)
 Resilience tests (Chaos Monkey, etc.)
 Load / Performance tests
 Vulnerability tests
 UI tests (Selenium, etc.)

 It’s a shame we call it “DevOps”, it should be “DevTestOps”!

Continuous Delivery for the Right Reasons

 Many are rushing to achieve continuous delivery but not for the
right reasons.

 98% automated deployment - - but can’t get the last bit.
 Frequent deployments but not infrequent customer releases.
 When deployments fail, still doing roll-back, not roll-forward.
 Achieved frequent releases but due to the number of failed
releases have reduced the % of availability.

 Not looking at root causes of failures stagnates the automated
delivery success rates.

April 8, 2013

Integrate the DevOps Tool Chain

 Dis-integrated tools in the delivery process reduce the ability to
automate deployments (fast, cheap, accurate)

 Integrate the DevOps tool chain:
 Start with continuous build (version control, build, continuous build, units)
 Quality tests show in dashboard and affect QA maintenance backlog
 Use proper repositories (Nexus, etc.), configuration management
(Puppet, Chef, etc.)
 Integrate with virtual & cloud environments where appropriate
 Use DevOps workflow automation (RunDeck) across the process

 Keeping the tool chain integrated is as important as the first-
time integration.

Architected for Operations

 Many applications aren’t architected to be easy to operate; this
is a HUGE problem.

 Architected for Operations attributes include:
 Ability to easily scale in or out without code changes (config/registry only)
 Ability to easily version or patch the system without taking it offline
 Ability to partially fail; e.g., keep taking inbound messages and queue them
 Ability to easily migrate the system (not hardcoded to infra layer)

 Operability of a system must be a primary concern in the non-
functional requirements

April 8, 2013

Instrumented for Operations

 Solution Architects incorrectly assume that operations will
instrument their system once they ‘throw it over the wall’.

 Instrumented for Operations activities include:
 System requirements mandate that warnings, errors, exceptions are logged
with unique identifiers; leverage unified logging where appropriate
 Complex multi-tiered, multi-component systems require additional
visibility of flow between systems (e.g., SQL calls, JSON messages, etc.)
 Clear direction given on infrastructure and application monitoring
 Instrumentation is used and tested in pre-production environments

 Proper instrumentation is maintains developers, testers and
operators sanity. It’s more than a nicety.

April 8, 2013

Open Source Dominates the Tooling

 Companies that are showing success in DevOps are utilizing
significant amounts of open source tooling.

 Less expensive, open source tooling is winning over commercial:
 Junit, Selenium, SoapUI, etc. are ubiquitous in .com and enterprise
 Ant, Maven, Jenkins, Nexus, etc are ubiquitous in .com and enterprise
 Puppet and Chef have moved beyond early adopters and are now being
used by the ‘early majority’.

 Open source solutions are being updated at a more rapid rate
than their commercial cousins. The wisdom of the crowds is
driving innovation.

April 8, 2013

DevOps on Cloud

 Infrastructure as a Service is the preferred environment for
many companies.

 Users of IaaS almost ALWAYS embrace DevOps principles &
technologies:
 AWS is promoting CloudFormation and OpsWorks
 Cloud solutions like ServiceMesh Agility offer DevOps accelerators
 Puppet & Chef have strong support for OpenStack, vCloud, etc.

 The rapid provisioning of IaaS makes it a natural fit for
deploying across dev, test, stage, prod and DR environments.

April 8, 2013

Renewed Focus on Metrics, SLA’s and Incentives

 MTTR, RTO and other operational metrics remain important but
are not enough.

 New Metrics and SLA’s include:
 Release rate, Quality of Release, Cost of Release
 System availability (as affected by patches, changes, etc.)
 Patch rate, In-Compliance %
 DR fire-drill success rate

 Progressive organizations have monetary incentives aligned
with metrics/SLA’s; plus or minus 15% of annual salary.
