getting faster How we got from a release every six
month TO daily releases Continuos Lifecycle 11.11.2013
AndrÉ von deetzen @vdandre Oliver Wehrens @owehrens
Migration what’s next Status Agenda one stack Lessons learned
Status How we started
150 DEV / QA / OPS
> 100 SOURCE REPOSITORIES
1 RELEASE EVERY SIX MONTH
1 TEAM TO RELEASE & DELIVER
1 DEPLOYMENT IN PRODUCTION
Technology stack PHP JAVA RUBY LINUX puppet tomcat C++ C
SQL perl python jboss httpd
development & production different installer other os bare metal vs
virtualisation different puppet versions other ways of monitoring
Wait whaT? How did we GET here? Features, Features, Features
faster, faster, faster (not really) solved the scaling problem upfront
Transition What did we do?
Time to market Analysis 6 Months 2 Weeks daily
Squeeze The existing
Automate as much as we can
From 6 to 3 Months
scrum no more waterfall
From 3 to 1 Month
optimize agile + automation
From 1 Month to 2 weeks
Still a monolith
Still nightly deployments
New Functionality?
We can do better!
One Stack (with variations)
new platform simplify unify loosely coupled daytime deployment disaster recovery
!
Three areas to change
Architecture (many) small services stateless independently deployable stable interfaces
Deployment MAKE RPM NOT WAR PUPPET with HIERA automatic vm
setup
Workflow staging build chain empower teaMs infrastructure
create virtual machine install yum, rpm, centos reboot smoketest lifecycle
configure puppet operate €€€
technology stack JVM Tomcat Centos 6 YUM & RPM Puppet
3 REST
deployment pipeline development release candidate certified release reference production
started with one new service and one team
Approach became very popular
existing services ? anti corruption Layer refactoring rewrite (better not
do it)
> 200 Deployments STAGED TO PRE-PRODUCTION ON OUR BEST DAY
IN 2013
2014 What’s next?
Automate all the things! Puppet for network components Automate firewalls
Increase visibility Infrastructure self service evaluate container based approach instead of VMs
lessons learned
Same environment & Tools Everywhere is essential
don’t get too fast, we could not deploy every delivery
had not enough Capacity for VMs in Development
Rewrite = Long time no roi
Spreading Knowledge can’t be fast enough
need to recreate any Machine automatically
Questions ? And yes, we’re hiring too! come talk to
us.
Thanks for your attention!
