WHAT IS DEVOPS?


AN IDEA OR COLLABORATIVE CULTURE/PHILOSOPHY BETWEEN

TECHNICAL TEAMS


UNIFIED PROCESSES AND TOOLS FOR FASTER END-TO-END DELIVERY

OF QUALITY SOFTWARE


NOT A JOB DESCRIPTION!


SO WHY SHOULD YOU CARE?


YOU CAN'T WAIT 6 MONTHS FOR A FEATURE UPGRADE/BUG FIX/ETC


SOLVE CONFIGURATION DRIFT ISSUES QUICKLY


KNOW EXACTLY WHAT'S WRONG, WHERE AND WHY


http://46zwyrvli634e39iq2l9mv8g.wpengine.netdna-cdn.com/wp-content/uploads/2013/06/DevOps-infinity-loop2.png


LAST BUT NOT LEAST, IMPROVE TEAM COMMUNICATION


SO WHAT'S THE RESULT OF DEVOPS?


IT'S REALLY BIG ACTUALLY...


DEVOPS PRACTICES AND IT PERFORMANCE IMPACT

ORGANIZATIONAL PERFORMANCE

http://www.slideshare.net/realgenekim/2014-state-of-devops-findings-velocity-conference


LET'S START WITH

INFRASTRUCTURE AS CODE


WHAT DO WE DEFINE AS INFRASTRUCTURE?





• Deploy, monitor and connect together all the pieces needed to run services for the organization

• Processes and tools for faster end-to-end delivery of quality services

• Automation comes built-in

WHY DEFINE INFRASTRUCTURE AS CODE?


• Desired state specified in text files

• Autonomic (self-corrects to desired state)

• State should be known through monitoring

• Remove snowflake servers

HOW DO WE DO THIS?


• Easy to read and edit

• Shareable

• Can use standard version control like Git or SVN

• Becomes executable documentation

WHY STORE THEM IN TEXT FILES?


node 'www2' {

class { 'apache': } # use apache module

apache::vhost { 'awesomewebsite.com': # define vhost

port => '80',

docroot => '/var/www/html'

}

}

SIMPLE EXAMPLE


user { root:

ensure => present,

password => '$ecretP@ssw0rd',

}

CHANGE ROOT PASSWORD


MANUALLY CONFIGURED ENVIRONMENTS ARE LIKE A HOUSE

OF CARDS IN A CHINA SHOP

- NEAL FORD


• Deploying, provisioning and scaling automatically is virtually impossible if every server is unique

• Adds friction between the requestor and the deployer

• Mistakes happen

• We're all human

SNOWFLAKE SERVERS


WHAT CAN HAPPEN IF YOU DON'T TREAT

INFRASTRUCTURE AS CODE?


UP TO 60% OF FAILURES ARE CAUSED BY HUMAN ERROR, NOT

HARDWARE FAILURE


EXAMPLE - KNIGHT CAPITAL GROUP

https://infocus.emc.com/wp-content/uploads/2012/08/KCG.jpg


• Manual deployment of new trading software

• 7 of 8 servers correctly updated

• Old function still alive on the 8th server led to…

KNIGHT CAPITAL GROUP - WHAT HAPPENED?


$440 MILLION LOSSIN 45 MINUTES


SO


TREAT YOUR INFRASTRUCTURE AS CODE


• Self documenting infrastructure

• You now have source code for how anything in your datacenter is setup

• Executable documentation

RECAP OF THE BENEFITS


ALRIGHT


THEN WHAT?


HOW ABOUTAUTOMATING SOME MORE?


• Jenkins CI

• Travis CI

• Codeship

• CloudFoundry

• OpenShift

DEPLOYMENT AUTOMATION


• Docker

• Framework for application container management

• HUGE community

CONTAINERS


• Splunk

• Loggly

• LogInsight

• ELK Stack– ElasticSearch– LogStash– Kibana

LOG MANAGEMENT


• vCenter Operations

• New Relic

• AppDynamics

• DataDog

PERFORMANCE MANAGEMENT


• Nagios

• Sensu

• VictorOps

• PagerDuty

MONITORING


• Slack

• HipChat

• Trello

• Asana

COMMUNICATION


• Github

• Quip

COLLABORATION


• And by smartly we mean cooperatively between Devs and Ops

• Will help operators understand what's running and happening in the infrastructure

• Will give developers insight into the underlying infrastructure and the way it behaves under load

USE THESE TOOLS SMARTLY


• Start talking about it

• Choose low-hanging fruit

• Learn, make wrong decisions, learn again

• Involve the broader team– Give books, presentations, blog posts etc.

SO HOW DO WE GET STARTED?
