DEVOPS VS. TRADITIONAL IT OPSSTATS, NUMBERS AND CONCLUSIONS
BY ZEROTURNAROUND
Oliver White (@theotown)Head of RebelLabs, ZeroTurnaround
A 5-MIN IGNITE TALK ABOUT HOW DEVOPS BEATS TRADITIONAL IT OPS, EVERY TIME.
Traditionally siloed team structures don't scale
Oppositng philosophies (Dev <3 change, Ops <3 stability)
Continuously evolving technologies & needs require more flexibility
Reminder: why we want DevOps
How do DevOps teams spend their time each week, compared to Traditional IT Ops teams?

DevOps vs. Traditional IT Ops: Overall work week
DevOps vs. Traditional IT Ops: Infrastructure improvements
What they're doing: testing processes and recovery plans and making sure these things work
DEVOPS SPENDS 33% MORE TIME IMPROVING INFRASTRUCTURE AGAINST FAILURES

INFRASTRUCTUREIMPROVEMENTS
(TEST PROCESSES AND RECOVERY PLANS)
DevOps vs. Traditional IT Ops: Handling Support
What they're doing: Handling support cases for operations infrastructure - i.e. when things go wrong
TRADITIONAL IT OPS REQUIRE NEARLY 60% MORE TIME PER WEEK TO HANDLE SPPORT CASES.

SUPPORT(HANDLING SUPPORT FOR OPS
INFRASTRUCTURE)
What they're doing: dropping everything to recover from failures or fix something urgently
DEVOPS SPENDS ABOUT 21% LESS TIME PUTTING OUT FIRES ON A WEEKLY BASIS.
DevOps wins!
21% less time putting out fires 37% less time handling support cases
With that extra time, DevOps spends 33% more time improving infrastructure, and they even spend 15% more time on self-improvement (education, training).
What about failures and recoveries?
Average team has 2 app failures per month
Recovery time is >30min for over 50% of all respondents.

HOW LONG DO RECOVERIES TAKE?
DevOps vs. Traditional IT Ops: Firefighting
71% of DevOps teams can recover
from failures in < 60min
40% of traditional IT Ops teams need >1 hr to recover
DevOps vs. Traditional IT Ops: Firefighting
Traditional IT Ops teams are almost 2x more likely to require 60+ minutes to recover
Recoveries in <30 minutes are 33% more likely for DevOps teams than traditional IT Ops
But what about releasing software?
Surely DevOps can't be THAT much better?
Wrong.
Ok ok, so DevOps recover faster...
Boom!
DevOps teams need less than HALF THE TIME to release an application version (36.6 min vs. 85.1 min).

Most app failures still occur due to software quality or lack of automation Most teams have <10% of their infrastructure configured with code (i.e. using Puppet, Chef)
Most teams have <10% of their smoke tests automated
Most teams don't test their recovery processes.
DevOps clearly wins, but still isn't perfect (hey!)
