Kris Buytaert discusses the Devops movement and how bringing developers and operations teams together earlier improves systems. He advocates for automation throughout the development and deployment process, from version control and testing to configuration management, monitoring, and upgrades. Adopting a Devops culture and practices like continuous integration, delivery, and deployment can help teams deploy better systems faster at lower risk.

Kris Buytaert ● I used to be a Dev, Then Became an Op ● Senior Linux and Open Source Consultant @inuits.be ● „Infrastructure Architect“ ● Building Clouds since before the Cloud ● Surviving the 10th floor test ● Co-Author of some books ● Guest Editor at some sites...
Alternative Titles ● Tales from Grumpy old Sysadmin ● Why your startup needs an automated infrastructure ● Devops, Devops, Devops th ● Surviving the 10 floor test ● Agile Administration
The community of developers whose work you see on the Web, who probably don’t know what ADO or UML or JPA even stand for, deploy better systems at less cost in less time at lower risk than we see in the Enterprise. This is true even when you factor in the greater flexibility and velocity of startups. Tim Bray , on his blog January 2010
The Old Days ● “Put this Code Live, here's a tarball” NOW! ● What dependencies ? ● No machines available ? ● What database ? ● Security ? ● High Availability ? ● Scalability ? ● My computer can't install this ?
Devs vs Ops
10 days into operation ● What High Load ? What Memory usage ? ● Are these Logs ? Or this is actualy customer data ? ● How many users are there , should they launch 100 queries each ?? Oh we're having 10K users ● Why is debugging enabled ? ● Who the fsck wrote this crap ?
11 days into operations
We can solve this ! ● Some people think the Ops work starts on deployment • Ops = both system, app as platform ! ● It starts much earlier ● Get Devs and Ops to talk asap
What's wrong with this ?
Talk about Non functional Reqs NOW! ● Security ● Backups ● High Availability ● Upgradability ● Configuration Mgmt ● Monitoring
During Development ● Version Control ● Automated Build ● Integrated Bugtracking ● Continous integration ● Integrated testing ● Automated deployment on test platforms

The full monty ● Behaviour and functional testing to test upgrades and new developments ● Automated Testing based on Continuous Integration ● Automated Test Deployments ● Automated Production Deployments ● Controlled Continuous Deployment
Going Live
Deploying ● Automated Deployments ● If my computer can't install it , the installer is borken ● Reproducable ● Think: • Kickstart, FAI, Preseeding, SystemImager Suite
An “ecosystem” that supports continuous delivery, from infrastructure, data and configuration management to business. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers, and operations, delivery teams can get changes released in a matter of hours — sometimes even minutes–no matter what the size of a project or the complexity of its code base. Continuous Delivery , Jez Humble
Configuration Mgmt ● Configure 1000 nodes, ● Modify 2000 files, ● Together ● Think : • Cfengine,Puppet, Chef ● Put configs under version control
Deployment isn't the End ● The job isn't done yet ● Monitoring ● Upgrading
High Availabilty
Scalability
Monitor
Surviving the test ! ● After 5+ years of preaching I`m not alone anymore ● Devops, a new Movement ! ● Join the movement ! • Devopsdays.org • Agile System Adminstration GoogleGroups
Devops a definition ● There is no definition ● It certainly isn't a role ● No strict rules ● No strict tools ● It's not even new ● If you aren't doing it already ... .. failure is upon you ... .... however ...
CAMS ● Culture ● Automation ● Measurement ● Sharing
