BLUE - GREEN DEPLOYMENT
HOW TO TEST LOCALLY?
Developer Operating Systems
None
Everything can be tested locally with vagrant (this means operating
system like in production, configuration management, deployment, building packages, needed network interfaces, ...) http://www.vagrantup.com
WHAT CHANGED IN OUR WORKFLOW?
TEAM IS RESPONSIBLE
EVERY COMMIT GOES TO PRODUCTION
DEPLOY ≠ FEATURE RELEASE
ROLL FORWARD
AUTOMATE ALL THE THINGS
IF IT HURTS DO IT MORE OFTEN (EXCEPT MEETINGS)
TEST SETUP
VISIBILITY
NEXT STEPS
DB DEPLOYMENT
COMPONENT PUPPET WITH HIERA
SAME KICKSTART IN DEV & PROD
FEEDBACK: LIVE DATA IN DEV WITH GRAPHITE
MEASURE, MEASURE, MEASURE
SELF HEALING
LESSONS LEARNED
#1 CLOSE TO PRODUCTION AS EARLY AS POSSIBLE
#2 EVERYTHING CAN BE AUTOMATED
#3 MANAGEMENT BUY IN
#4 SELF-SERVICE INFRASTRUCTURE FOR TEAMS
#5 RESISTANCE WILL RISE
#6 IT’S WORTH THE EFFORT
~ 30 MIN TO CR
#7 FEEDBACK IS NEVER FAST ENOUGH
