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

But is it a perfect storm?

Ex: Agile + Business Pressures
Agile: Parallel Development
Business: Short cycle
times
Demand: New Test
Env. in Minutes

Plus an increasingly viable alternative
Demand: New Test
Env. In Minutes
Alternative:Cloud PaaS
Deliver or..

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

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

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

There’s nothing keeping you from asking, “How do I make your life easier?”

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

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.”
