Why is DevOps all the rage? In this presentation I argued that operations is under a great deal of pressure from changing infrastructure and business climates. Operations is going to need to change, and the core changes it needs to make are in line with the foundations of DevOps. This presentation has a number of "image" slides. If you want to hear the words that go with thing, watch the replay of the presentation. Available here: http://www.urbancode.com/html/resources/webinars/The_DevOps_Imperative.html

Infrastructure
Larger Scale, Greater Complexity and Clouds
Gartner survey found most viewed their environments as “very complex” (50%), or
“out of control” (17%)

Agile: Parallel

Business:

Alternative:

mandatory” - Deming

I could do this all day
 Need: Automated Deployments:
- Shorter Test Cycles + More Dev Change
- Larger scale + Shorter Outage Windows
- More Releases + Can’t Add Staff
 Need: Automated Configuration Application
- Larger Scale + More Moving Parts + More Change
 Need: Better Dev / Ops Collaboration
- More new apps + Less Time to Plan
- Performance Critical + Perf Tests Stink
 Need: Awesome redundancy / failover
- More critical apps + More internal / external risk

That’s DevOps
“We embrace faster change and
manage risk by building a
collaborative culture and automating
like crazy.”

Velocity: not just speed

Feedback is key
• Deliver Quickly
• Test Often
• Monitor Production

Beware, Conway’s Law

Four strategies for facing Conway’s Law
1. Hire engineers that have skills in development, test
and system administration

Practices: What to Google after this event
 Devs wear pagers
 Test environments on
demand
 Version control of
environment definitions
 Zero downtime
deployments
 Automated database
deployments
 Release manifests &
snapshots
 Developers attend release
post-mortems
 Ops included in product
planning.
 Routine failover testing
 Production immune system
 Canary deployments

27. UrbanCode, an IBM Company. Proprietary and Confidential ©2013
The industry is already moving this way
 Infrastructure support teams have been doing this
for years
 Gartner survey*: “…even though the concept itself is
still somewhat ambiguous, a significant number of
organizations (47%) are in some phase of
experimenting with DevOps.”

Key Points
 Ops will change
- Apps critical + complex infrastructure + agile/lean
 DevOps
- Embraces change and manages risk
- By collaborating and automating
