USE MODERN ARCHITECTURES AND TECHNOLOGIES
MONOLITHS CAN BE HARD ▸ All functionality is in one process ▸ Scale by replicating the monolith on multiple servers @kmugrage https://www.thoughtworks.com/insights/blog/microservices-nutshell
DEVELOP SMALLER PIECES MICROSERVICE ARCHITECTURE ▸ Each element of functionality is in a separate service ▸ Scale by distributing these services across servers, replicating as needed @kmugrage https://www.thoughtworks.com/insights/blog/microservices-nutshell

CONTINUOUS DELIVERY IS THE ABILITY TO GET CHANGES OF ALL TYPES—INCLUDING NEW FEATURES, CONFIGURATION CHANGES, BUG FIXES AND EXPERIMENTS—INTO PRODUCTION, OR INTO THE HANDS OF USERS, SAFELY AND QUICKLY IN A SUSTAINABLE WAY. Jez Humble @kmugrage https://continuousdelivery.com/
MORE HOMEWORK @kmugrage
CONTINUOUS DELIVERY IS WHAT YOU “DO” AS PART OF A DEVOPS CULTURE Me @kmugrage
A PREREQUISITE TO CD CONTINUOUS INTEGRATION
CI THEATRE The ThoughtWorks tech radar recently recommended putting a hold on the tech team anti-pattern, CI Theatre. CI Theatre describes the illusion of practicing continuous integration (CI) while not really practicing it. @kmugrage https://www.gocd.org/2017/05/16/its-not-CI-its-CI-theatre/
CI THEATRE In another ThoughtWorks study only 10% of participants acknowledged that having a CI server was not the same as practicing CI. @kmugrage https://www.gocd.org/2017/05/16/its-not-CI-its-CI-theatre/
ARE YOU PRACTICING CI? @kmugrage
CONTINUOUS DELIVERY PIPELINE @kmugrage
CONTINUOUS DELIVERY IS NOT JUST CONTINUOUS INTEGRATION WITH A PLUGIN AND A COUPLE EXTRA STEPS Me @kmugrage
CONTINUOUS DELIVERY VS CONTINUOUS DEPLOYMENT @kmugrage http://gofor.cd/cd_vs_cd
OUR TEAMS Product Team @kmugrage Security Team Compliance Team
OUR CONTINUOUS DELIVERY PIPELINE UNIT TESTS @kmugrage FUNCTIONAL TESTS DEPLOY STAGING DEPLOY PRODUCTION
EXAMPLES OF THINGS WHICH ARE BAD ▸ Deploying insecure software ▸ Deploying non-performant software ▸ Deploying non-complying software ▸ Deploying ineffective software @kmugrage https://www.gocd.org
THE PURPOSE OF A CONTINUOUS DELIVERY PIPELINE IS TO KILL A RELEASE CANDIDATE Me, and a lot of other people @kmugrage
OUR CONTINUOUS DELIVERY PIPELINE UNIT TESTS FUNCTIONAL TESTS DEPLOY STAGING SECURITY TESTS (OWASP, OTHERS) COMPLIANCE TESTS (SERVERSPEC, INSPEC) @kmugrage DEPLOY PRODUCTION
SORRY, THERE’S NO SILVER BULLET BUT THESE ARE SOLVED PROBLEMS AND THERE IS A LOT OF HELP
